About the article "Inside Llewyn Davis", section "Production".

Candidate passages:
The pay-cable rights to the new CBS Films' library are held by CBS's premium cable networks Showtime and The Movie Channel.
Sony Pictures also has foreign theatrical and home entertainment distribution rights for all CBS Films products. 
CBS Television Distribution (CTD) is an American television distribution company, formed from the merger of CBS Corporation's two domestic television distribution arms CBS Paramount Domestic Television and King World Productions, including its home entertainment arm CBS Home Entertainment.
The division, the main distribution arm of CBS Paramount Network Television (now CBS Television Studios) and of the CBS television network, was formed on September 26, 2006 by CBS Corporation and was headed by Roger King, the CEO of King World until his death in 2007.
The company handles distribution rights to acquired series, mini-series, and made-for-TV films from the Paramount Television libraries (such as those of Desilu Productions, Paramount Television, Viacom Productions and Enterprises, Republic Pictures Television, Big Ticket Entertainment, Spelling Television, and Worldvision Enterprises), and series, mini-series, and made-for-TV films from the CBS television libraries (such as those by CBS Productions, King World Productions, the majority of those by Group W Productions, and its own first-run broadcast syndication and off-network television series).
CBS also handles the TV rights to much of its own theatrical films.
The company formerly distributed the film libraries from Paramount Pictures and Republic Pictures, among others.
The company is also responsible for international television distribution rights to series by Rysher Entertainment including certain HBO series through its CBS Studios International division.
This would mark the sixth distribution name for CBS as CBS Television Film Sales was the first (1952–1958), CBS Films, Inc. was the second (1958–1967), CBS Enterprises was the third (1968–1971), Eyemark Entertainment was the fourth (1995–2000), and CBS Paramount Domestic Television was the fifth (2006–2007).
From 2006-2008, CTD distributed the DreamWorks Television and DreamWorks Pictures libraries in conjunction with Tribune Entertainment, after Viacom's acquisition of DreamWorks in February 2006, but before the studio was spun off.
These distribution rights are now held by Disney-ABC Domestic Television (for live-action TV series and post-9/2005 live-action films) and Trifecta Entertainment & Media (for earlier live-action films and all animated productions).
Until May 2009, CTD distributed the Paramount Pictures library on television.
By then, CBS also dropped the name "Paramount" from television for good, renaming CBS Paramount Television to CBS Television Studios.
Paramount has also joined up with Trifecta.
However, CTD continues to distribute films currently copyrighted by CBS (or a subdivision thereof), including those films from Cinema Center Films and CBS Theatrical Films, along with a few select entries to which CBS bought ancillary rights in later years, such as "My Fair Lady".
The current moniker for CTD's overseas distribution arm is CBS Studios International (since 2009).
Its predecessors were CBS Broadcast International and CBS Paramount International Television.
In 2012, CBS Television Distribution ceased to be a corporate entity, becoming a division of CBS Studios, Inc. 
Set in 1961, "Inside Llewyn Davis" was inspired by the cultural disconnection within a New York–based music scene where the songs seemed to come from all parts of the United States except New York, but whose performers included Brooklyn-born Dave Van Ronk and Ramblin' Jack Elliott.
Well before writing the script, the Coens began with a single premise: suppose Van Ronk got beat up outside of Gerde's Folk City in the Village.
The filmmakers employed that idea in the opening scenes, then periodically returned to the project over the next couple of years to expand the story around a fictional character.
One source for the film was Van Ronk's posthumously published (2005) memoir, "The Mayor of MacDougal Street."
According to the book's co-author, Elijah Wald, the Coens mined the work "for local color and a few scenes."
The character is a composite of Van Ronk, Elliot, and other performers from the New York boroughs who performed in the Village at that time.
Joel Coen remarked that "the film doesn't really have a plot.
That concerned us at one point; that's why we threw the cat in.
"Shooting was complicated by an early New York spring, which interfered with the bleak winter atmosphere that prevails throughout the film, and by the difficulty of filming several cats, who, unlike dogs, ignore the desires of filmmakers.
On the advice of an animal trainer, the Coens put out a casting call for an orange tabby cat, which is sufficiently common that several cats would be available to play one part.
Individual cats were then selected for each scene based on what they were predisposed to do on their own.
Producer Scott Rudin, who worked with the Coens on "True Grit" and "No Country for Old Men", collaborated on the project.
StudioCanal helped finance it without an American distributor in place.
"After shooting in New York City and elsewhere last year...the brothers finished the movie at their own pace", wrote Michael Cieply in a January 2013 "The New York Times" interview with Joel Coen ahead of a private, pre-Grammys screening in Los Angeles.
"They could have rushed it into the Oscar season but didn’t."
On February 19, CBS Films announced it had picked up the U.S. domestic distribution rights for about $4 million.
StudioCanal has rights to international distribution and foreign sales.
In February 1961, Llewyn Davis (Oscar Isaac) is a struggling folk singer in New York City's Greenwich Village.
His musical partner, Mike Timlin, has committed suicide; his recent solo album "Inside Llewyn Davis" is not selling; he has no money and is sleeping on the couches of friends and acquaintances.
After performing in the Gaslight Cafe, Llewyn is beaten up by a shadowy suited man for heckling the previous night.
He sleeps at the apartment of his older friends, the Gorfeins.
When he leaves the next morning, the Gorfeins' ginger cat escapes.
Llewyn takes the cat to the apartment of his friends Jim (Justin Timberlake) and Jean (Carey Mulligan) Berkey.
Jean tells him she is pregnant, and fearing that Llewyn may be the father, asks him to pay for an abortion.
After he sleeps on their couch, the Gorfeins' cat escapes again.
On Jim's invitation, Llewyn, as part of the "John Glenn Singers", records a novelty song with Jim and Al Cody (Adam Driver).
Needing money immediately, Llewyn agrees to $200 with no royalties.
At the gynecologist's office, Llewyn sets up Jean's appointment and discovers that a previous girlfriend, whose abortion he also paid for, decided to keep the baby and move to Akron without telling him.
Llewyn and Jean argue about his lack of direction.
He spots what he believes to be the Gorfeins' cat and returns it that evening.
Asked to play after dinner, he reluctantly performs "Fare Thee Well", a song he had recorded with his deceased partner Mike.
When Mrs. Gorfein starts to sing Mike's harmony, Llewyn snaps.
Mrs. Gorfein leaves the table crying, then returns with the cat, having realized that it is not theirs.
Llewyn leaves with the cat.
Llewyn rides with two musicians driving to Chicago: the laconic beat poet Johnny Five (Garrett Hedlund) and the odious jazz musician Roland Turner (John Goodman).
At a roadside restaurant, Roland collapses from a heroin overdose.
The three stop on the side of the highway to rest.
When a police officer tells them to move on, Johnny resists and is arrested.
Without the keys, Llewyn abandons the car, leaving the cat and the unconscious Roland behind.
In Chicago, Llewyn auditions for Bud Grossman (F. Murray Abraham).
Grossman says Llewyn is not suited to be a solo performer but suggests he might incorporate him in a new trio he is forming.
Llewyn rejects the offer and hitchhikes back to New York.
Driving, he hits what he fears may be the same cat.
In New York, he pays $148 in back dues to rejoin the merchant marine union, and visits his ailing father.
Llewyn searches for his seaman's license so he can ship out with the merchant marines, but his sister has thrown it out.
At the Gaslight, Pappi claims he had sex with Jean.
Llewyn becomes upset (presumably at feeling he was swindled by Jean for abortion money) and heckles a woman as she performs.
He goes to the Gorfeins' apartment, where they graciously welcome him.
He is amazed to see that their actual cat, named Ulysses, has found his way home.
The scene from the beginning of the film then replays.
Llewyn performs at the Gaslight.
Pappi teases him about his heckling the previous evening and tells him that a friend is waiting outside.
As Llewyn leaves the building, a young and unknown Bob Dylan takes the stage and begins to sing.
Behind the Gaslight, Llewyn is beaten by the shadowy suited man for heckling the previous night's performer, his wife.
He watches as the man leaves in a taxi and quietly bids him "au revoir".
