a cyclic redundancy check ( crc ) is an error-detecting code commonly used in digital networks and storage devices to detect accidental changes to raw data .

blocks of data entering these systems get a short check value attached , based on the remainder of a polynomial division of their contents .

on retrieval , the calculation is repeated and , in the event the check values do not match , corrective action can be taken against data corruption .

crcs can be used for error correction , see bitfilters .

crcs are so called because the check ( data verification ) value is a redundancy ( it expands the message without adding information ) and the algorithm is based on cyclic codes .

crcs are popular because they are simple to implement in binary hardware , easy to analyze mathematically , and particularly good at detecting common errors caused by noise in transmission channels .

because the check value has a fixed length , the function that generates it is occasionally used as a hash function .

the crc was invented by w. wesley peterson in 1961 ; the 32-bit crc function of ethernet and many other standards is the work of several researchers and was published in 1975 .

3 . cyclic redundancy codes  the cyclic redundancy check , or crc , is a technique for detecting errors in digital data , but not for making corrections when errors are detected .  it is used primarily in data transmission . in the crc method , a certain number of check bits , often called a checksum , are appended to the message being transmitted .  the receiver can determine whether or not the check bits agree with the data , to ascertain with a certain degree of probability whether or not an error occurred in transmission . if an error occurred , the receiver sends a “negative acknowledgement” ( nak ) back to the sender , requesting that the message be retransmitted .  the technique is also sometimes applied to data storage devices , such as a disk drive .

cyclic redundancy checking is a method of checking for errors in data that has been transmitted on a communications link . a sending device applies a 16 - or 32 - bit polynomial to a block of data that is to be transmitted and appends the resulting cyclic redundancy code ( crc ) to the block . the receiving end applies the same polynomial to the data and compares its result with the result appended by the sender . if they agree , the data has been received successfully . if not , the sender can be notified to resend the block of data .

4 . data storing  data are stored in bytes , which consist of 8 bits each . thus any set of data can be considered as sequence of bytes or bits . in computer communication usually the bits are considered to be independent and a bit sequence is limited by the size of data blocks ( or frames , packets , datagrams etc . ) . thus we consider the problem to check whether a finite sequence of bits is changed unintentionally , e . g . by transmission errors or faulty memories .  cyclic redundancy check performs a special operation that can be interpreted as polynomial division . the residual of this division is used as redundancy information and we will explore in this paper which types of errors can be detected by this method .

the cyclic redundancy check ( crc ) error is generic in nature and can be caused by numerous factors . typically this means that a tape read / write error has occurred . this is usually caused by dirty read / write heads in the tape drive . clean the tape drive and try the job again . if the problem persists , consider trying a different tape . finally , the problem could be with cabling , termination or other hardware issue .
the mathematics behind crcs initially appears daunting , but it doesn’t have to be . the idea is given a block of n bits , let’s compute a checksum of a sort to see if the n bits were damaged in some way , for instance by transit over a network . the extra data we transmit with this checksum is the “redundancy” part of crc , and the second c just means this is a “check” to see if the data are corrupted ( as opposed to an ecc code , which both detects and corrects errors ) . the cyclic part means it uses cyclic codes , which is where people tend to get lost in the math . if you look at the wikipedia page for cyclic codes , it starts by discussing galois field arithmetic and goes uphill from there .
. . . to be specific , pdcch carries the resource scheduling information to decode the data channel ( e . g . , resource assignment , modulation order , code rate ) . on top of these , cyclic redundancy check ( crc ) is added to test the decoding error [ 12 ] . since the crc bit stream is scrambled with a user index ( called radio network temporary identifier ) , only scheduled user can pass the crc test . . . .

cyclic redundancy codes ( crcs ) provide a first line of defense against data corruption in many networks . unfortunately , many commonly used crc polynomials provide significantly less error detection capability than they might . an exhaustive exploration reveals that most previously published crc polynomials are either inferior to alternatives or are only good choices for particular message lengths .
the itu - ts ( ccitt ) has a standard for a 16 - bit polynomial to be used to obtain the cyclic redundancy code ( crc ) that is appended . ibm ' s synchronous data link control and other protocols use crc - 16 , another 16 - bit polynomial . a 16 - bit cyclic redundancy code detects all single and double - bit errors and ensures detection of 99 . 998 % of all possible errors . this level of detection assurance is considered sufficient for data transmission blocks of 4 kilobytes or less . for larger transmissions , a 32 - bit crc is used . the ethernet and token ring local area network protocols both used a 32 - bit crc .
cyclic redundancy checks fall into the same category as parity bits , check digits , and checksums : their use is to detect transmission errors . depending on the error model assumed ( i . e . , what types of transmission errors are to be expected , which typically depends on the transmission media ) , different forms of checking are appropriate . before starting to look at crcs per se , we thus look at the other mechanisms first , which also help introducing a few concepts with illustrative examples .
cyclic redundancy check ( crc ) is a widely used technique for detecting errors in digital data , and is suitably used in data transmission , data storage and algorithms for the selection of processing cores in multi - core processor devices , for example . a crc code typically is computed through binary polynomial division using a computational device that performs a calculation on a first part of the message and then provides the result from the initial calculation as feedback to itself for a subsequent calculation on a second part of the message .

if you are familiar with the parity bit sometimes used in uart communication , you know something about error detection . but the parity bit is a rather pathetic error - detection mechanism ; actually , as far as i can tell , most of the error - detection methods are more or less pathetic compared to the cyclic redundancy check ( crc ) , which has clearly emerged as the dominant approach—some big names in digital communication ( including can , usb , and ethernet ) use a crc as part of their data - transfer protocol .

. . . if all of the detected errors can be corrected by retransmission , even with a high 10 −8 raw physical channel ber , better than 10 −25 residual ber can be achieved when it is used for error detection only . cyclic redundancy check ( crc ) codes , on the other hand , can create larger hamming distances 21 2223 , and therefore are more powerful in error detection . the undetected error probabilities at various packet sizes and crc code sizes are shown in figs . 5 , 6 , and 7 . . . .

the cyclic redundancy check is a way to detecting small changes in blocks of data . error detection is especially important when computer programs are transmitted or stored , because an error of even one bit ( perhaps out of hundreds of thousands ) is often sufficient to make a program faulty . although a few errors in a text file might be acceptable ( since the text can be reedited when received or recovered ) , an error - free file is preferable . an error - correcting protocol triggered by crc error - detection can provide this accuracy at low cost .

as another example , a method is provided for calculating a cyclic redundancy check ( crc ) code for a message in a data stream . a message including a first data block and a second data block is received . the first data block of the message is received at a first crc calculator . a first crc value is calculated based at least in part on the first data block , and provided to a second crc calculator for calculating a second crc value based on the second data block of the message and the first crc value , the second crc calculator being different from the first crc calculator .

the bit operations change slightly : moving the input byte into the msb of crc requires now a shift by 24 . also the check for the most significant bit uses a different mask of 0x8000000 instead of 0x8000 .
high - speed digital data can be transmitted on voice telephone systems such as autovon . autovon will pass digital data at 4800 b / s and 9600 b / s using the state - of - the - art codex modem at bit error rates of the order of 0 . 0001 to 0 . 00001 . errors on the autovon channel can be modeled by markov chains , and these models can be used for the design of cyclic redundancy check ( crc ) polynomial codes . the performance of three crc codes is calculated , and , within the limits of the data sample size , their performance is demonstrated to be consistent with results obtained from the raw - error - pattern data by simulation .
when you select this check box , the block flips the input data on a bytewise basis prior to entering the data into the shift register . for this application , the input frame length ( and any current input frame length for variable - size signals ) divided by the value for the checksums per frame parameter must be a multiple of eight . when you clear this check box , the block does not flip the input data .
a crc error indicates that some data in your zip file ( . zip or . zipx ) is damaged . crc stands for cyclic redundancy check . it is a calculation made from all the data in a file to insure accuracy . when you add a file to a zip file , winzip calculates a crc value for the file and saves the value in the zip file . when you later extract the file from the zip file , winzip calculates the crc of the extracted file and compares it to the value stored when the file was zipped . if these two crc values do not match , the file that was extracted does not match the original file , and winzip will display a crc error message .
can data frames and remote frames contain a safeguard based on a crc polynomial : the transmitter calculates a check sum from the transmitted bits and provides the result within the frame in the crc field . the receivers use the same polynomial to calculate the check sum from the bits as seen on the bus - lines . the self - calculated check sum is compared with the received on . if it matches , the frame is regarded as correctly received and the receiving node transmits a dominant state in the ack slot bit , overwriting the recessive state of the transmitter . in case of a mismatch , the receiving node sends an error frame after the ack delimiter .

crc ( cyclic redundancy check ) is a checksum algorithm to detect inconsistency of data , e . g . bit errors during data transmission . a checksum , calculated by crc , is attached to the data to help the receiver to detect such errors . refer also to [ 1 ] for a short or to [ 4 ] for a very detailed crc introduction . crc is based on division . the actual input data is interpreted as one long binary bit stream ( divident ) which is divided by another fixed binary number ( divisor ) . the remainder of this division is the checksum value . however , reality is a bit more complicated . the binary numbers ( divident and divisor ) are not treated as normal integer values , but as binary polyonimals where the actual bits are used as coefficients .
so an extra 4 bytes from somewhere were being included in the crc . to check this , i added another 4 zero bytes to the end of my difference file and ran pycrc over it . this time , i got the correct checksum .
the cksum program processes a representation of the input stream length following the input . it returns 930766865 ( 0x377a6011 ) on the check string , processed internally as 31 32 33 34 35 36 37 38 39 09 . see the definition for details .
it isn’t perfect—it only detects certain errors that it was designed to check . ( specifically , the parity bit successfully detects all one - bit errors in each 7 - bit block of data , but potentially can fail if worse data corruption occurs . )

there are two most common error detection techniques one is parity check and the other is cyclic redundancy check or crc . by this method we can identify that the received packet is correctly received without any error or received incorrectly with error . suppose we need to transmit k bytes , in this case , few of the bytes are appended to k bytes which say make up n bytes , these n bytes are transmitted instead of k bytes and at the receiver crc is calculated and compared with the transmitted crc and hence error detection decision is made at the receiver . there are many ways one can implement this , such as modulo 2 arithmetic operations , polynomial method and digital logic method . in modulo 2 method , modulo 2 sum of k bytes is calculated and appended at last as checksum and at the receiver the same last byte is compared with calculated checksum of received bytes . the most popular crc method used in today ' s wireless technologies are based on polynomial method . there are various crc polynomials as mentioned below such as crc32 , crc16 . they are used in wireless communication systems such as mobile wimax ( ofdma ) and fixed wimax ( ofdm ) implementations and in networking protocol implementations .

check value [ optional ] : this value is not required but often specified to help to validate the implementation . this is the crc value of input string
123456789
or as byte array : [ 0x31 , 0x32 , 0x33 , 0x34 , 0x35 , 0x36 , 0x37 , 0x38 , 0x39 ] .
verdict : to check files in a zip archive against files on box using the crc in zip , we ' ll need to use a utility that can calculate the
crc32b ” variant for a file ( php ' s hash _ file ( ) would work , but it will load the whole file into memory ) .
advanced design techniques ensure reliable operation under extreme conditions while stripping away complexity and advancing ease - of - use , the gigepack provides three key elements : certified products , free drivers and copy - ready evaluation boards , and microchip’s free lancheck ® design check service . together , they ensure interoperability , rapid development and robust board design .
in some protocols the packet header changes frequently . if the crc includes the changing part , the crc will have to be recomputed . this raises two issues : - the complete computation is expensive - the packet is not protected against unwanted changes between the last check and the recomputation fortunately , changes in the header do not imply a need for completed crc computation . the reason is the linearity of the crc function . namely , with i1 and i2 denoting two equal - length blocks of information bits , crc ( i ) denoting the crc check bits calculated for i , and + denoting bitwise modulo - 2 addition , we have crc ( i1 + i2 ) = crc ( i1 ) + crc ( i2 ) .
you do not need to download or install anything because the check disk utility is included in windows computer . this utility exists for scanning and repairing any errors affecting the drive . there is an alternative for mac computers , known as the disk utility but this error is a lot less common on mac computers , so we are just going to focus on windows machines .
a binary $ ( n , k ) $ cyclic code has $ 2 ^ k $ codewords , they correspond to a binary polynomial $ c ( x ) $ of degree less than $ n $ . a particular code is specified by a generator polynomial $ g ( x ) $ , which must be of degree $ n - k $ and must be a factor of $ x ^ n + 1 $ .
error correction goes way back in computing . one of the first things i ran into while understanding the ascii character set was parity . the seven - bit ascii character set in some computers used the 8th bit as a check bit to see if the character had been transmitted correctly . if the character had an odd number of ones in the lower 7 bits , the 8th bit was set to a 1 , otherwise 0 .
crcs are essentially systematic cyclic codes , in which the parity length $ n - k $ is relatively small ( typically 16 or 32 ) and $ n $ is large ( say $ n = 2 ^ { 15 } - 1 = 32767 $ ) ; however , one does not usually code the full length block , but a smaller message of arbitrary length , to which the computed parity bits will be appended . as explained here , this is mathematically equivalent to assuming that the unused bits of the total block are zero .
if you decide to go ahead with the scan and repair you may find out that it does not work . if this is the case , you should try to access the check disk utility by looking for it under your programs and clicking on it ; or access it via the command prompt . in order to do this , you will need to find the command prompt program , usually under accessories . for this to work , however , you will need to have administrator privileges .
because the left side is a multiple of $ g ( x ) $ , that must be one of the codewords of our cyclic code ( equivalent to the previous one ; but , mind you , it ' s not the same : it has the same codewords , but mapped to different input messsages ) . this code has the nice property of being the concatenation of the original raw message $ m ( x ) $ shifted $ n - k $ positions , and the
parity polynomial
$ p ( x ) $ ( degree less than $ n - k $ ) .
] , which seems pretty good . but for a single additional byte , the crc technique is about 460 times less likely to let an error pass undetected . in practice , the difference is much greater because the crc will detect all cases of just a few errors , and these cases are most common . the cost is a 2 - byte crc value in every block . for example , the xmodem protocol sends data in 128 - byte blocks ; these blocks can be crc error - checked with an additional two bytes - - an error - check overhead of about 1 . 5 percent [
if the problem is caused by an optical disk , such as a dvd or a cd , you should remove the disk and check it for scratches . if the disk does not seem to be scratched , then it is probably dirty , in which case you will need to dust it off . if you have never done this , grab a soft cloth and clean the disk gently but thoroughly ( make sure that the cloth is dry ) . if the disk is scratched , however , it is probably beyond repair , in which case you could just try buying a new one and disposing of the damaged one .
. . . thereby , the hamming - code implementation can correct multi - bit errors , in particular , all burst errors up to the length of a machine word ( 32 bit in our case ) . besides burst errors , the crc variants ( seetable 2 ) cover all possible 2 - bit and 3 - bit errors in objects smaller than 256 mib by the crc - 32 / 4 code [ 29 ] . all implementations use the wait - free synchronization algorithm from section 4 . additionally , we integrated a check of virtual - function table pointers into the gop , similar to [ 30 ] . . . .
] extended fujiwara ' s technique for efficiently calculating the minimum distance through the weight distribution of the dual code and explored a large number of crc codes with 24 and 32 redundancy bit . they explored several codes built as a multiplication of several lower degree irreducible polynomials . in the popular class of ( x + 1 ) * deg31 - irreducible - polynomial they explored 47000 polynomials ( not all the possible ones ) . the best they found has d = 6 up to block lengths of 5275 and d = 4 up to 2 ^ 31 - 1 ( bits ) . the investigation was done in 1993 with a special purpose processor . by comparison , the ieee - 802 code has d = 4 up to at least 64 , 000 bits ( fujikura stopped looking at 12 , 144 ) and d = 3 up to 2 ^ 32 - 1 bits .
we thought that we might be able to take advantage of these two pre - computed checksums , since we would be able to quickly tell if a file uploaded via zip - uploading was likely identical to an existing file in the same location ( note : it’s not a good idea to rely on crc checks entirely , due to the possibility of collisions ) . we were going to check the crcs of files in the target location against crcs stored in the zip header as the files were extracted . we expected that unix cksum would generate the same kind of crc32 that zip does . however , this was not true - cksum says it generates crcs the way ethernet does in its man page , which is different than zip . the crazy part of this puzzle is that cksum actually generates crc32 checksums that match no crc specification at all , including ethernet’s .
] measured the weights of all words of all shortened versions of the ieee 802 . 3 code of 32 check bits . this code is generated by a primitive polynomial of degree 32 : g ( x ) = x ^ 32 + x ^ 26 + x ^ 23 + x ^ 22 + x ^ 16 + x ^ 12 + x ^ 11 + x ^ 10 + x ^ 8 + x ^ 7 + x ^ 5 + x ^ 4 + x ^ 2 + x + 1 and hence the designed distance of it is only 3 . this distance holds for codes as long as 2 ^ 32 - 1 . however , the frame format of the mac ( media access control ) of the data link layer in ieee 802 . 3 , as well as that of the data link layer for the ethernet ( 1980 ) forbid lengths exceeding 12 , 144 bits . thus , only such bounded lengths are investigated in [
that the sequence of powers of alpha , the root of p ( x ) , which are roots of g ( x ) , includes three consecutive powers - - alpha ^ 0 , alpha ^ 1 , alpha ^ 2 ) . hence , every 3 single bit errors are detectable . wolf found that different shortened versions of a given code , of the same codeword length , perform the same ( independent of which specific indexes are omitted from the original code ) . he also found that for the unshortened codes , all primitive polynomials yield codes of the same performance . but for the shortened versions , the choice of the primitive polynomial does make a difference . wolf [ wolf94j ] found a primitive polynomial which ( when multiplied by x + 1 ) yields a generating polynomial that outperforms the ccitt one by an order of magnitude . for 32 - bit redundancy bits , he found an example of two polynomials that differ in their probability of undetected burst of length 33 by 4 orders of magnitude . it so happens , that for some shortened codes , the minimum distance , or the distribution of the weights , is better than for others derived from different unshortened codes . baicheva , et . al .

“mildred pierce” is not about southern california during the depression . it’s about mildred pierce . why is it that so many viewers either want to focus on mildred’s role as a working woman / successful businesswoman and somewhat ignore her relationship with her elder daughter , veda ? is it because veda was never punished , as she was in the 1945 movie ? or is it because no one wants to acknowledge that mildred was complicit in the development of veda’s monstrous personality ?

adapted to film in 1945 , mildred pierce has long been one of my favorite old hollywood stories , so i was very excited to come across a vintage copy of the book at a used book shop . now i can say that i’ve read the book , seen the film several time , and watched the hbo miniseries… so , here are my thoughts on them all !
rob reiner ' s film rests on broad , sweeping proclamations about the importance of factual reporting .
fidelity may be a buttress of marriage , but it is sometimes a burden on film adaptations .
because of script problems some of the film was improvised by the actors together with michael curtiz .
michael curtiz and joan crawford would clash frequently over crawford ' s insistence that mildred pierce would always be dressed glamorously . curtiz felt this was inappropriate for a working mother while crawford said it was because mildred was proud and wanted to project an upwardly mobile appearance .

mildred pierce begins to shift between past and present when the protagonist discloses her back story to the police . this film technique brings to light mildred’s character development and eventually exposes her husband’s murderer . it also intrigues the viewer , leaving them constantly guessing who the killer is . for example , in the introduction , the viewer is lead to believe that mildred is the culprit and later that her ex - husband is guilty of the crime . as the movie progresses , the viewer is even tricked into suspecting wally killed mildred’s husband out of jealousy . this enhances the shock the audience feels when the film ultimately reveals that veda is the true murderer .

mildred pierce provides insight to the psychological desire to be needed that so many crave . so many aspects of the human psychological condition and experience can be seen in this classic film . the aspect of the deep desire to be needed is brilliantly delivered to the audience through a riveting and enticing storyline , presenting to the audience a tale of desire and passion and the constant battle of mildred pierce to live her life in the way that most fulfilled her . the director did a superb job in the film when it came to the film form . the film started off in present time and then moved to the past in a chronological order , occasionally returning to the present until the final scene which finished the film in the present . also , the narration of the film added a great effect to the movie as it was coming from the main character mrs . mildred pierce and then slowly vanished with the audience barely noticing it was missing . although through her journey mildred encountered many obstacles and tribulations , she continued to fight on for her daughter , consistently trying to buy herself a place into veda’s life . she fought until the end when even all she had done no longer counted , and she lost the person most important in her life , the one she craved to be needed by the most .

i find it interesting that you focused on the psychological features of this film because those were the aspects that stood out to me as well , as opposed to the murder story line . while this film certainly has some film noir characteristics , with the inclusion of the murder of monte , i was not riveted to the screen until the film started to delve into mildred’s past . her obsession with being needed was really the driving force for the entire film , and it could be argued that had it not been for her desire to be needed , the murder may not have occurred in the first place .

the film is less concerned with placing gauguin in his historical context than it is with his emotional tribulations .

a scheduling conflict means that the melodrama research group will meet in jarman 6 for the screening of mildred pierce at 4 . 30pm on tuesday the 20th of may – a little later than originally planned .
in an interview with david frost , joan crawford revealed that michael curtiz wanted barbara stanwyck to play mildred pierce , but joan won him over after a screen test with her co - star ann blyth .
the fact that you make mention of the flashback is a winner in my opinion . the flashback in this film showed the different side of mildred’s character and how she grew throughout the film . it also was a way for the plot to move from mildred’s story of why her ex husband could not have killed monte , and it turns the flashback into the actual murder mystery story .
the misleading narration of mildred pierce has its parallel in crime fiction , particularly the thrillers of the 1940s . see this entry on the site for more background . a ruth rendell novel , wolf to the slaughter ( 1967 ) , contains a boldly misleading opening that is somewhat similar to what happens in our film .

michael curtiz’ film was also discussed in relation to james m . cain’s novel . it was noted that curtiz’ film kept a flavour of cain’s punchy social commentary . we were a little surprised that under hollywood’s production code fairly obvious references to extra - marital sex and pregnancy were included . the film was still , as variety noted in its review , fairly cleaned up from the novel . while in cain’s novel veda became a successful opera singer – and therefore profited from her hideous behaviour – in curtiz’ film she ends up a low - rent cabaret act . a more significant difference is mildred’s response to finding her eldest daughter veda ( ann blyth ) and mildred’s second husband monte ( zachary scott ) in a compromising position . in cain’s novel mildred is so enraged she attempts to strangle her daughter . such an understandable response is not present in curtiz’ film , though . instead mildred’s suffering sacrifice is played to the hilt . mildred’s one refusal of veda’s demands occurs when veda has shot monte dead . mildred soon reconsiders , however , and is prepared to take responsibility for the crime herself .
i pity the screenwriter who had to adapt the novel , mildred pierce , from 289 pages down to an hour and 57 minute movie . the main character , mildred pierce , repeatedly steps out of the traditional role for women of that era , and challenges society’s norms about class . significant changes were made to the plot while converting it from book to movie . these changes add up to a significant difference in the meaning .

to audiences who’ve read or seen the film version of “mommie dearest” — the story of the very unhappy childhood reportedly inflicted by crawford on her own adopted daughter , christina — however , the film resonates in a way that it did not when first seen seven decades ago , as “mildred pierce” is the story of a mother so self - sacrificing and dedicated to her daughter that the girl grows up well groomed , well educated and completely ungrateful .
mildred pierce was also famously adapted in the much - loved 1945 film starring joan crawford – the actress won an oscar for her portrayal . “i deliberately didn’t see the film because i felt i might feel under terrible pressure , ” winslet says . “i mean , who wouldn’t , for god’s sake ? joan crawford won an academy award in that role and i just didn’t want to scare myself . acting is scary enough as it is . ”
james m . cain ' s novel mildred pierce : comparing the book and movie version mildred pierce is one of the greatest novels written by james m . cain . after the success of the novel , the hollywood film came out , produced by jerry wald . the novel and the movie are very different from each other . “james m . cain sent several letters of complaint to producer jerry wald , objecting to the changes wald wanted to make , especially the dramatic idea of making veda a washout musically and putting her in a tawdry nightclub” ( bennett notes ) . the three main differences in the film were , the murder of monte , veda not having a successful career , and the time period only covering 1941 to 1945 . the main difference between the film and the novel
, the film , is one of those that gets better with each viewing – with wonderful performances across the board , a gorgeous noir and story that render it unforgettable . it is certainly worthy of a post dedicated to its merits as a film alone . that one is to come – one of these days . i’ll give one view i have toward the film now – that is that although joan crawford won the best actress academy award for her depiction of the film’s title character , and a damn good acting performance it is , it’s ann blyth’s portrayal of veda that lingers . she’s magnificent in a despicable sort of way . actually , she may well be the most hateful character in all of film to me . here’s the film’s original trailer to whet your appetite if you’ve yet to see the film…
when mildred pierce ' s ( joan crawford ) wealthy husband leaves her for another woman , mildred decides to raise her two daughters on her own . despite mildred ' s financial successes in the restaurant business , her oldest daughter , veda ( ann blyth ) , resents her mother for degrading their social status . in the midst of a police investigation after the death of her second husband ( zachary scott ) , mildred must evaluate her own freedom and her complicated relationship with her daughter .
along these same lines , in cain’s novel mildred has a very healthy sexual appetite and enjoys physical relationships with both wally and monte . the film steers away from this characterization after that day at the beach because it is simply not acceptable . in the film the character of wally pursues her but never quite gets anywhere .

although mildred ' s maternal sacrifice is portrayed as noble , some have claimed that the film is cautionary and anti - feminist , with mildred presented as a typical 1940 ' s post - war housewife whose ' american dream - fulfilling ' role - switching movement from suburban , middle - class home - maker to divorced , successful business entrepreneur ( restaurant - chain owner ) results in corruptive , destructive disaster ( both financial and personal ) . this was symbolized in the film in movements from bright , daytime s . california scenes to dark , criminal , nightmarish scenes . the film ' s taglines described mildred ' s character :

the film opens with a dramatic shooting rather than an argument between mildred and her husband , which was how the novel opened . the rest of the film’s story is told through the frame of a police interrogation , with mildred recounting her sordid tale through flashbacks . though it differs from the book , this structure is successfully used , bringing a great sense of tension and a noir - style edge to the story .

back in 1992 i wrote an essay about this technique . “cognition and comprehension : viewing and forgetting in mildred pierce ” focuses on the murder of monte beragon in the 1945 film . a revised version of the essay appears in poetics of cinema and is now available on this website . the piece tries to show that a cognitive approach to comprehension and recollection can explain how a film shapes viewers’ responses—in this case , creating mystery while making viewers forget certain things they’ve seen .

the replay explains why mildred contemplated drowning herself afterward : she was in despair at the couple’s treachery and the crime that veda committed . when suicide was blocked , mildred tried to frame wally for the murder in order to protect veda . and the replay suggests that it’s not mildred but veda who drives off from beach house , leaving mildred to drift down to the pier .
this film , a tremendous box - office hit and critical success , was an adaptation by ranald macdougall and catherine turney ( and william faulkner ) of james m . cain ' s 1941 ' hard - boiled ' novel of the same name . cain ' s original novel was a satire about bourgeois values , and a tale of poor parenthood . [ note : cain was responsible for two sources for film noir classics - his 1936 novella for double indemnity ( 1944 ) and his best - selling work for mildred pierce ( 1945 ) . ] atypical for film noirs , the main protagonist in the film is a female - but she is typically brought down by a femme fatale - her own daughter . the intriguing murder story is told with a flashback structure reminiscent of citizen kane ( 1941 ) . successful promotional copy for the film read :

mildred pierce won crawford the oscar she desperately coveted and still endures as her most popular picture . while the film launched her on a new phase as an icon of pulp torment , it is distinct from the rest because it is superbly nasty noir that plays havoc with the era ' s american ideals of women , home , mom and her apple pie .
and “mildred pierce , ” a beautifully made mini - series that begins sunday on hbo and stars kate winslet , proves the point . it’s a five - part drama that is loyally , unwaveringly true to james m . cain ’s 1941 novel and somehow not nearly as satisfying as the 1945 film noir that took shameless liberties with plot , characters and settings .
mildred pierce is the third joan crawford film i have been lucky enough to see in theaters this past year or so . the first one i saw was johnny guitar , and i really enjoyed it . the second was pretty recently , and it was flamingo road , and was so much better than i had expected . you can read that review here :
a last musing : might viewers exposed to publicity come into the film expecting mildred to be the culprit ? ( on mildred ‘s marketing , see mary beth haralovich , “selling mildred pierce : a case study in movie promotion , ” in thomas schatz , boom and bust : american cinema in the 1940s ( scribners , 1997 ) , 196 - 202 . ) the french poster below seems to put her in a doorway with a smoking gun . or is that veda in the doorway ? perhaps the uncertainty of the narration is prefigured by this advertisement .
