Phil is stabbed through the ear in a bathroom stall while trying to eavesdrop on strange whimpering noises. The killer, wearing a Ghostface costume, then returns to the screening and sits beside Maureen before mortally stabbing her. At first the audience believes she is part of the raucous acting out by audience members until she falls dead in front of the cinema screen. The following day, the news media including local journalist Debbie Salt, descend on Windsor College where Sidney Prescott, a theatre major, now studies alongside her best friend Hallie and her new boyfriend Derek, fellow Woodsboro survivor Randy, and Derek's best friend Mickey. Sidney receives prank calls but is oblivious to the recent killings until someone instructs her to watch the news. Two other Woodsboro survivors arrive at the campus: officer Dewey Riley to help Sidney, and reporter Gale Weathers to cover the case. Gale tries to stage a confrontation between Sidney and Cotton Weary, who is attempting to gain fame from his exoneration for the murder of Sidney's mother. After Gale forcibly brings Sidney to Cotton, Sidney angrily hits Gale. Later that evening, Sidney goes to a party with Hallie. At a sorority house, Ghostface kills fellow student Cici. After all the partygoers leave, the killer then crashes the party and attempts to murder Sidney, though Derek intervenes. The killer injures Derek but Dewey and the police arrive, causing the killer to flee. The next morning, Gale discusses the case with the police. Upon realizing that Cici's real name is Casey, she concludes that the killer is a copycat who targets students who share the same names as the Woodsboro murder victims.

input question: Generate a question that has the following answer: A flashback. for the following movie plot: In a brief scene in 1964, an aging, overweight Italian American, Jake LaMotta (Robert De Niro), practices a comedy routine. The rest of the film then occurs in flashback. In 1941, LaMotta is in a major boxing match against Jimmy Reeves, where he received his first loss. Jake's brother Joey LaMotta (Joe Pesci) discusses a potential shot for the middleweight title with one of his Mafia connections, Salvy Batts (Frank Vincent). Some time thereafter, Jake spots a 15-year-old girl named Vikki (Cathy Moriarty) at an open-air swimming pool in his Bronx neighborhood. He eventually pursues a relationship with her, even though he is already married. In 1943, Jake defeats Sugar Ray Robinson, and has a rematch three weeks later. Despite the fact that Jake dominates Robinson during the bout, the judges surprisingly rule in favor of Robinson and Joey feels Robinson won only because he was enlisting into the US Army the following week. By 1947, Jake marries Vikki. Jake constantly worries about Vikki having feelings for other men, particularly when she makes an off-hand comment about Tony Janiro, Jake's opponent in his next fight. His jealousy is evident when he brutally defeats Janiro in front of the local Mob boss, Tommy Como (Nicholas Colasanto), and Vikki. As Joey discusses the victory with journalists at the Copacabana, he is distracted by seeing Vikki approach a table with Salvy and his crew. Joey speaks with Vikki, who says she is giving up on his brother. Blaming Salvy, Joey viciously attacks him in a fight that spills outside of the club. Como later orders them to apologize, and has Joey tell Jake that if he wants a chance at the championship title, which Como controls, he will have to take a dive first. In a match against Billy Fox, after briefly pummeling his opponent, Jake does not even bother to put up a fight. He is suspended shortly thereafter from the board on suspicion of throwing the fight, though he realizes the error of his judgment when it is too late. He is eventually reinstated, and in 1949, wins the...???

Please answer this: Generate a question that has the following answer: Senator John Yerkes Iselin for the following movie plot: During the Korean War, the Soviets capture a U.S. platoon and take them to Manchuria in Communist China. Some days later, all but two of the soldiers return to the U.S. lines and Staff Sergeant Raymond Shaw (Laurence Harvey) is credited with saving their lives in combat by his fellow platoon members. Upon the recommendation of the platoon's commander, Captain Bennett Marco (Frank Sinatra), Raymond is awarded the Medal of Honor. When asked to describe him, Marco and the other soldiers automatically respond, "Raymond Shaw is the kindest, bravest, warmest, most wonderful human being I've ever known in my life." Deep down, however, they know that Shaw is a cold, sad, unsympathetic loner. Following his return to America, Marco, who has since been promoted to major, suffers from a recurring nightmare in which a hypnotized Shaw blithely and brutally murders the two missing soldiers before an assembly of military brass from the Communist nations, during a practical demonstration of a revolutionary brainwashing technique. Marco wants to investigate, but has no solid evidence to back his claims and thus receives no support from Army Intelligence. However, Marco learns that another soldier from the platoon, Allen Melvin (James Edwards), has had the same nightmare. When Melvin and Marco separately identify some of the men in the dream as leading figures in communist governments, Army Intelligence agrees to help Marco investigate. Sgt. Shaw (Harvey, left) meets Major Marco (Sinatra, right), after having jumped into a lake in Central Park, New York. Meanwhile, Shaw's mother, Mrs. Eleanor Iselin (Angela Lansbury), drives the political career of her husband and Shaw's stepfather, Senator John Yerkes Iselin (James Gregory), a McCarthy-like demagogue who is widely dismissed as a fool. Senator Iselin raises his political profile when he claims that varying numbers of communists work within the Department of Defense. However, unknown to Raymond, Mrs. Iselin herself is actually a Communist agent with a plan intended to secure...
