Movie plot title: Sling Blade Movie plot: Karl Childers (Billy Bob Thornton) is an intellectually disabled Arkansas man who has been in the custody of the state mental hospital since the age of 12 for having killed his mother and her lover. Although thoroughly institutionalized, Karl is deemed fit to be released into the outside world. Prior to his release, he is interviewed by a local college newspaper reporter, to whom he recounts committing the murders with a Kaiser blade, saying, "Some folks call it a sling blade. I call it a kaiser blade." Karl says he thought the man was raping his mother. When he discovered that his mother was a willing participant in the affair, he killed her also. Thanks to the doctor in charge of his institutionalization (James Hampton), Karl lands a job at a repair shop in the small town where he was born and raised. He befriends 12-year-old Frank Wheatley (Lucas Black) and shares some of the details of his past, including the killings. Frank reveals that his father was killed - hit by a train - leaving him and his mother on their own. He later admits that he lied, and that his father committed suicide. Frank introduces Karl to his mother, Linda (Natalie Canerday), as well as her gay friend, Vaughan Cunningham (John Ritter), the manager of the dollar store where she is employed. Despite Vaughan's concerns about Karl's history in the mental hospital, Linda allows him to move into her garage, which angers Linda's abusive alcoholic boyfriend, Doyle Hargraves (Dwight Yoakam). Karl bonds with Linda, who makes him biscuits to eat, and also with Vaughan, who tells Karl that a gay man and a mentally challenged man face similar obstacles of intolerance and ridicule in small-town America. Karl quickly becomes a father figure to Frank, who misses his father and despises Doyle. Karl is haunted by the task given to him by his parents when he was six or eight years old to dispose of his premature, unwanted, newborn brother. He visits his father (Robert Duvall), who has become a mentally unbalanced hermit living in the dilapidated home...

Question: What was Jake's role in the film Movie plot title: Body Double Movie plot: Jake Scully (Craig Wasson) is a struggling actor who has lost his role as a vampire in a low-budget horror movie after his claustrophobia thwarts shooting. After returning home to discover his girlfriend cheating on him, he is left without a place to stay. At a method acting class he meets Sam (Gregg Henry) who closely monitors Scully's revelation of his fears and the childhood cause of his claustrophobia. They go to a bar where Scully is offered a place to stay; Sam's friend has left town temporarily and needs a house-sitter for his ultra-modern home in the Hollywood Hills. During the tour of the house with Scully, Sam is especially ecstatic about one feature: a female neighbor, Gloria Revelle (Deborah Shelton), who erotically dances at a specific time each night. Sam has even set up a telescope which Scully cannot resist using voyeuristically to watch her. One night he sees Gloria being abused by a boyfriend. When she goes shopping the next day, Scully decides to follow her. Gloria makes calls to an unknown person promising to meet them. Scully also notices a disfigured "Indian," a man he had noticed watching Gloria a few days prior. Scully follows her to a seaside motel where apparently Gloria has been stood up by the person she was there to meet. On the beach the Indian suddenly snatches her purse. Scully tries to pursue him but in a nearby tunnel his claustrophobia restrains him and Gloria walks him out of it. They begin to impulsively and passionately kiss before she retreats. That night Scully is again watching through the telescope when the Indian returns. The man is seen breaking into Gloria's home. Scully races to save her but is attacked by Gloria's vicious dog.

Movie plot title: Cabin by the Lake Movie plot: The film opens with Stanley (Judd Nelson) on his boat in the middle of Summit Lake. After speaking with his agent, Regan (Susan Gibney) over the phone, Stanley accesses a hidden room in his house revealing a young woman who is chained to the floor by her ankle. He greets the woman and calls her Kimberly (Daniella Evangelista) as he places a plate of food in front of her. When he leaves the room, Kimberly walks over to the mirror and begins to cry, unaware that Stanley is studying her on the other side. Afterwards, Stanley brings her a fresh change of clothes and instructs her to dress, before gagging her with an orange and binding her hands behind her back. He forcibly escorts her onto his boat and drives out to the middle of Summit Lake, where he ties a cement block around her ankles. Curious about her predicament, he asks Kimberly how she feels, but the terrified woman does not respond. Stanley then pushes her into the lake, but promptly pulls her back up by the hair to study her expression before letting her sink to the bottom. Later, Stanley returns home to resume working on his script using the details he had gleaned from his latest victim. The next morning, he dives to the bottom of Summit Lake to tend his "garden", which consists of several women kidnapped and drowned in a similar fashion. Seeking yet another victim, Stanley discovers Mallory (Hedy Buress), a young woman working at a movie theater. Intrigued by her self-confessed fear of water, Stanley follows Mallory after she leaves work and swerves in front of her, slamming the brakes on his van and forcing their vehicles to collide. After checking on Mallory, Stanley turns his attention to his dogs, which are heard barking from the van. Mallory follows him, but before she can react, Stanley throws the back doors wide and pushes her into the van, which is completely empty save for the recording of barking dogs, and an ominous message spelled out in yellow tape that reads, "I'm the person your mother warned you about." Stanley locks his new victim...
