The fun begins when Lucky (Wesley Snipes) is released from prison and tries to lead a respectable life despite his troubled past. Lucky frequently reflects on the wisdom of his grandfather who always told him "sometimes without bad luck, it would seem you don't have any luck at all." This theme is manifested throughout the film. Shortly after his release from prison, Lucky tries to get back on his feet but ends up a victim of Hurricane Katrina's wrath, and loses his newly found life. After moving back to New York, Lucky is dealt another blow when the government withdraws funds for his samba dance classes which he uses to try to keep kids off of the streets. This unfortunate event leads to Lucky enduring the bad influences of two old friends from his past life as a criminal, who lure Lucky to a strip club under the false pretense of one his friend's birthday. When a drug [gun?] deal with some dangerous mobsters goes bad, Lucky is now on the run with a feisty Cuban stripper from the strip club, Angie (Jackie Quinones), and over $500,000 in American currency, which is wired with marking dye.Throughout the film, there are cuts of an unconventional and troubled couple, known to the police as the sawtooth serial killers. James Hiroyuki Liao plays Chang, an egotistical and maniacal accomplice to Cass, played by Cybill Shepherd, a mother of a mentally challenged boy. Motivated by Cass' son's unpleasant experiences with society's rejection of mentally challenged individuals, the couple brutally kidnaps, tortures, and presumably kills their abductees, recording their exploits on video, possibly for future viewing.These two stories merge at the end as Angie and Lucky find themselves caught up in the path of violence, and Lucky ends up an unlikely hero by saving the life of a would-be victim of the sawtooth killers. Lucky, choosing to have a positive outlook on the events by using perspective gained from his grandfather, characterizes the events by describing them as being "the luckiest day in an unlucky man's life." Lucky and Angie go on to receive a $200,000 reward which had been offered by the police for information leading the capture, arrest, and/or prosecution of the sawtooth killers., Question: Who are the sawtooth serial killers?
Answer: Cass and Chang

A group of children are playing an elimination game in the courtyard of an apartment building in Berlin[5] using a chant about a murderer of children. A woman sets the table for dinner, waiting for her daughter to come home from school. A wanted poster warns of a serial killer preying on children, as anxious parents wait outside a school.Little Elsie Beckmann leaves school, bouncing a ball on her way home. She is approached by Hans Beckert, who is whistling "In the Hall of the Mountain King" by Edvard Grieg. He offers to buy her a balloon from a blind street-vendor and walks and talks with her. Elsie's place at the dinner table remains empty, her ball is shown rolling away across a patch of grass and her balloon is lost in the telephone lines overhead.In the wake of Elsie's death, Beckert sends an angry letter about his crimes to the newspapers, from which the police extract clues using the new techniques of fingerprinting and handwriting analysis. Under mounting pressure from city leaders, the police work around the clock. Inspector Karl Lohmann instructs his men to intensify their search and to check the records of recently released psychiatric patients, to look for those with a history of violence against children. They stage frequent raids to question known criminals, disrupting underworld business so badly that Der Schranker (The Safecracker) calls a meeting of the city's crime lords. They decide to organize their own manhunt, using beggars to watch the children.The police discover two clues corresponding to the killer's letter in Beckert's rented rooms. They wait there to arrest him.Beckert sees a young girl in the reflection of a shop window. Following her, he is thwarted when the girl meets her mother. When he encounters another young girl, he succeeds in befriending her but the blind beggar recognizes his whistling. The blind man tells one of his friends, who tails the killer with assistance from other beggars he alerts along the way. Afraid of losing him, one young man chalks a large M (for Morder, murderer in German) on his hand, pretends to trip and bumps into Beckert, marking the back of his clothing.The beggars close in. When Beckert realizes he is being followed, he hides inside a large office building just before the workers leave for the evening. The beggars call Der Schranker and a team of criminals arrives. They tie up and torture a guard for information and after capturing the remaining watchmen, they search the building from coal cellar to attic, finally catching Beckert. When a watchman manages to trip the silent alarm, the crooks narrowly escape with their prisoner before the police arrive. One man is captured and tricked into revealing the purpose of the break-in (nothing was stolen) and where Beckert would be taken.The criminals drag Beckert to an abandoned distillery to face a kangaroo court. He finds a large, silent crowd awaiting him. Beckert is given a "lawyer", who gamely argues in his defense but fails to win any sympathy from the "jury". Beckert delivers an impassioned monologue, saying that his urges compel him to commit murders that he later regrets, while the other criminals present break the law by choice. His "lawyer" points out that the presiding "judge" is wanted on three counts of totschlag (a form of homicide in German law). Beckert pleads to be handed over to the police, asking, "Who knows what it's like to be me?" Just as the enraged mob is about to kill him, the police arrive to arrest both Beckert and the criminals.As the real trial passes, five judges prepare to pass judgement on Beckert. Before the sentence is announced, the shot cuts to three of the victims' mothers crying. Elsie's mother says no sentence would bring back the dead children and "One has to keep closer watch over the children"; the screen goes black as she adds, "All of you".[6], Question: Who sends an angry letter to the newspapers?
Answer: Beckert

The future United States is a dystopic irradiated wasteland known as the Cursed Earth. On the east coast lies Mega-City One, a violent metropolis with 800 million residents and 17,000 crimes reported daily. The only force for order are the Judges, who act as judge, jury and executioner. Judge Dredd is tasked by the Chief Judge with evaluating new recruit Cassandra Anderson, a powerful psychic who failed the aptitude tests to be a Judge.In Peach Trees, a 200-storey slum tower block, drug lord Madeline Madrigal, also known as "Ma-Ma", executes three rogue drug dealers by having them skinned alive, infused with Slo-Mo (an addictive new drug which reduces the user's perception of time to 1% of normal) and thrown down the atrium from the top floor. Dredd and Anderson are sent in to investigate and learn of a drug den, which they raid. They arrest a thug named Kay, whom Anderson's mind probe reveals to be the one who carried out the drug dealers' executions. Dredd decides to take him in for questioning. In response, Ma-Ma's forces seize the tower's security control room and seal the building, using its blast shields under the pretence of a security test, preventing the Judges from leaving or summoning help.Ma-Ma orders Dredd and Anderson killed, forcing the Judges to fight their way through dozens of armed thugs. Arriving at the 76th floor, the Judges are assaulted by Ma-Ma and her men with Vulcan cannons that rip through the walls, killing numerous residents. The Judges breach an outer wall and call for backup. Meanwhile, Ma-Ma sends her henchman Caleb to search for the Judges. When they meet, Dredd throws Caleb off the tower in full view of Ma-Ma.Dredd suspects Ma-Ma is desperate to keep Kay quiet and beats him for information. Anderson reads Kay's mind and learns that Peach Trees is the centre of Slo-Mo production and distribution. Anderson suggests they hide while awaiting assistance but Dredd insists they move up the tower and pursue Ma-Ma. Judges Volt and Guthrie respond to Dredd's call, but Ma-Ma's computer expert denies them entry by persuading them the security system is malfunctioning. A pair of armed teens confront Dredd and Anderson, allowing Kay to disarm and overpower Anderson. Kay then escapes with her as hostage, and takes her to Ma-Ma's base on the top floor.While Dredd works his way towards Ma-Ma, she calls in the corrupt Judges Lex, Kaplan, Chan and Alvarez. The four relieve Volt and Guthrie from duty and are allowed into the building. Dredd encounters Chan and is suspicious that he does not ask about Anderson's status. Seeing his cover blown, Chan attacks Dredd, but is killed. Meanwhile, Kay tries to execute Anderson with her own weapon, but the pistol's DNA scanner does not recognise him and explodes, taking his arm off. She escapes and later encounters Kaplan, whom she promptly kills after reading Kaplan's mind. Elsewhere, Dredd kills Alvarez but runs out of ammunition, and is shot by Lex in the abdomen. Lex moves in to execute Dredd, but Dredd stalls him long enough for Anderson to arrive and kill Lex.Anderson and Dredd obtain the code to Ma-Ma's apartment from her computer expert and confront her. Ma-Ma tells Dredd that, in the case of her death, a device on her wrist will detonate explosives on the top floors, destroying the building. Dredd reasons that the detonator's signal will not reach the explosives from the ground floor, so he forces Ma-Ma to inhale Slo-Mo and throws her down the atrium to her death.In the aftermath, Anderson accepts that she has failed her evaluation by getting disarmed, and leaves. The Chief Judge asks Dredd about Anderson's performance; he responds that she has passed., Question: What is Madeline Madrigal also known as?
Answer: Ma-Ma
