question:
Mark Lewis meets Dora, a prostitute, covertly filming her with a camera hidden under his coat. Shown from the point of view of the camera viewfinder, tension builds as he follows the woman into her home, murders her and later watches the film in his den as the credits roll on the screen.
Lewis is a member of a film crew who aspires to become a filmmaker himself. He also works part-time photographing soft-porn pin-up pictures of women, sold under the counter. He is a shy, reclusive young man who hardly ever socialises outside of his workplace. He lives in the house of his late father, renting most of it via an agent, while posing as a tenant himself. Helen, a sweet-natured young woman who lives with her blind mother in the flat below his, befriends him out of curiosity after he has been discovered spying on her on her 21st birthday party.
Mark reveals to Helen through home movies taken by his father that, as a child, he was used as a guinea pig for his father's psychological experiments on fear and the nervous system. Mark's father would study his son's reaction to various stimuli, such as lizards he put on his bed and would film the boy in all sorts of situations, even going as far as recording his son's reactions as he sat with his mother on her deathbed. He kept his son under constant watch and even wired all the rooms so that he could spy on him. Mark's father's studies enhanced his reputation as a renowned psychologist.
Mark arranges with Vivian, a stand-in at the studio, to make a film after the set is closed; he then kills her and stuffs her into a prop trunk. The body is discovered later during shooting by a female cast member who has already antagonised the director by fainting for real at points which are not in the script. The police link the two murders and notice that each victim died with a look of utter terror on her face. They interview everyone on the set, including Mark, who always keeps his camera running, claiming that he is making a documentary.
Helen goes out to dinner with Mark, even persuading him to leave his camera behind for once. Her mother finds his behaviour peculiar, aware how often Mark looks through Helen's window. Mrs. Stephens is waiting inside Mark's flat after his evening out with her daughter. She senses how emotionally disturbed he is and threatens to move, but Mark reassures her that he will never photograph or film Helen.
A psychiatrist is called to the set to console the upset star of the movie. He chats with Mark and is familiar with Mark's father's work. The psychiatrist relates the details of the conversation to the police, noting that Mark has "his father's eyes." Mark is tailed by the police who follow him to the newsagents where he takes photographs of the pin-up model Milly (two versions of this scene were shot; the more risqu version is credited as being the first female nude scene in a major British feature, although even on the racier version, Milly only exposes one breast for a few seconds). Slightly later, it emerges that Mark must have killed Milly before returning home.
Helen, who is curious about Mark's films, finally runs one of them. She becomes visibly upset and then frightened when he catches her. Mark reveals that he makes the movies so that he can capture the fear of his victims. He has mounted a round mirror atop his camera, so that he can capture the reactions of his victims as they see their impending deaths. He points the tripod's knife towards Helen's throat, but refuses to kill her.
The police arrive and Mark realises he is cornered. As he had planned from the very beginning, he impales himself on the knife with the camera running, providing the finale for his documentary. The last shot shows Helen crying over Mark's dead body as the police enter the room.
answer:
Who says Mark has his father's eyes?

question:
Fred Madison (Bill Pullman), a Los Angeles saxophonist, receives a message on the intercom of his house from an unknown man, who says: "Dick Laurent is dead". During a break at a show one night, Fred calls his home but Ren e (Patricia Arquette), his wife, does not answer any of the home's ringing telephones. Arriving home later, Fred finds her sleeping in their bed. The next morning, Ren e finds a VHS tape on their porch which contains a videotape of their house. After having sex one night, Fred sees Ren e's face as that of a pale old man, then tells Ren e of a dream he had about someone resembling her being attacked. As the days pass, more tapes arrive showing the interior of their house and even shots of the pair asleep in bed. Fred and Ren e call the police but the detectives they send over offer no assistance.
Fred and Ren e then attend a party being thrown by Andy (Michael Massee), Ren e's friend. At the party, the pale old man Fred dreamed about approaches Fred, claiming to have met him before. The man then says he is at Fred's house at that very moment and even somehow answers the house phone when Fred calls it. Fred asks Andy who the man is, and Andy replies: he is a friend of Dick Laurent's. Fred, terrified and confused, leaves the party and heads home with Ren e. The next morning, another tape arrives and Fred watches it alone. To his horror, it shows him hovering over Ren e's dismembered body. He is arrested for her murder, tried, found guilty and sentenced to death. Shortly after arriving at death row, Fred is plagued by frequent headaches and strange visions of the Mystery Man, a burning cabin in the desert and a strange man driving down a dark highway.
During a routine cell check, the prison guard is shocked to find that the man in Fred's cell is now Pete Dayton (Balthazar Getty), a young auto mechanic. Since Pete has committed no crime, he is released into the care of his parents, who take him home. Pete is then followed by two detectives who are trying to find out more about him. The next day, Pete returns to work at the garage where he is soon called on by gangster Mr. Eddy (Robert Loggia), to fix his car. Mr. Eddy takes Pete for a drive, on which Pete witnesses Mr. Eddy chase and beat down a tailgater. The next day, Mr. Eddy returns to the garage with his mistress, Alice Wakefield (also played by Arquette) and his Cadillac for Pete to repair. Later, Alice returns to the garage alone and invites Pete out for dinner. Soon, Pete and Alice begin a secret liaison, meeting each other at run-down motels every night. Alice soon begins to fear that Mr. Eddy is privy to their affair and concocts a scheme to rob her friend Andy and leave town. Alice then reveals to Pete that Mr. Eddy is actually an amateur porn producer named Dick Laurent.
At home, Pete gets a phone call from Mr. Eddy and the Mystery Man (which eerily mirrors Fred and the Mystery Man's earlier conversation), which distresses Pete so much that he decides to go along with Alice's plan to escape. Alice tells Pete what he must do to carry out her plan to rob Andy but Andy puts up unexpected resistance and ends up dead, accidentally impaling himself on the edge of his glass coffee table. Pete notices a photograph showing Alice and Ren e together, with Alice claiming that the blonde woman in the photo is her. Later, when police are at the house investigating Andy's death, the same photo shows only Ren e with Andy and Mr. Eddy; Alice is inexplicably missing from the shot.
Pete and Alice arrive at an empty cabin in the desert, the same one Fred had envisioned. The two start having sex but during the act Alice gets up, walks up the stairs to the cabin and disappears inside. Pete suddenly transforms back into Fred Madison. Upon searching the desert cabin, he meets the Mystery Man who begins filming and chasing Fred with a hand-held video camera, revealing himself to be the camerman from earlier. Fred escapes and drives to the Lost Highway Hotel, where he finds Mr. Eddy and Ren e having sex. After Ren e leaves, Fred kidnaps Mr. Eddy, beats him and slits his throat. The Mystery Man then shoots Mr. Eddy dead and whispers something to Fred. The Mystery Man disappears and Fred drives off in Mr. Eddy's car. Fred drives to his old house, buzzes the intercom and says: "Dick Laurent is dead". When the two detectives then drive up to the house, Fred runs back to his car and drives off with the detectives in pursuit. As it gets dark, Fred is shown speeding down the highway pursued by the police. Fred suddenly begins convulsing and screaming, before the familiar image of the highway at night is seen.

Who is Eddie's mistress?

question:
In this novel Burroughs focuses on a younger member of the family established by John Carter and Dejah Thoris, protagonists of the first three books in the series. The heroine this time is their daughter Tara, princess of Helium, whose hand is sought by the gallant Gahan, Jed (prince) of Gathol. Both Helium and Gathol are prominent Barsoomian city states.
Tara meets Prince Gahan of Gathol, and is initially unimpressed, viewing him as something of a popinjay. Later she takes her flier into a storm and loses control of the craft, and the storm carries her to an unfamiliar region of Barsoom. After landing and fleeing from a pack of ferocious Banths (Martian lions), she is captured by the horrific Kaldanes, who resemble large heads with small, crab-like legs. The Kaldanes have bred a symbiotic race of headless human-like creatures called Rykors, which they can attach themselves to and ride like a horse. The Kaldanes imprison Tara, intending to fatten her up, then eat her. While imprisoned, Tara manages to win over one of the Kaldanes, Ghek, with her lovely singing voice.
Gahan, who has fallen in love with Tara, sets out to find her, only to find himself caught up in the same storm, and he falls overboard while attempting to rescue one of his crew. He stumbles upon Bantoom, realm of the Kaldanes, and manages to rescue Tara, and together with Ghek they flee in Tara's crippled flier. Tara doesn't recognize Gahan as the prince she met earlier, as he is worn from his ordeals and no longer dressed in his fancy clothes. In light of her earlier reaction to him, Gahan decides to keep his identity secret, and identifies himself instead as a Panthan (warrior) called Turan.
The three of them manage to reach the isolated city of Manator. Gahan ventures into the city seeking food and water, but is tricked and taken prisoner by the inhabitants. Tara and Ghek are also captured. In Manator, captives are forced to a fight to the death in the arena, in a modified version of Jetan, a popular Barsoomian board game resembling Chess; the living version uses people as the game pieces on a life-sized board, with each taking of a piece being a duel to the death.
answer:
What are captives forced to do in Manator?
