Question: What is the problem with stage actress Elisabet Vogler? Title: Persona Movie plot: Persona begins with images of camera equipment and projectors lighting up and projecting dozens of brief cinematic glimpses, including a crucifixion, an erect penis, a tarantula spider, clips from a comedic silent-film reel first seen in Bergman's Prison (depicting a man trapped in a room, being chased by Death and Satan), and the slaughter of a lamb. The last, and longest, glimpse features a boy who wakes up in a hospital next to several corpses, reading Michail Lermontov's A Hero of Our Time ("Var Tids Hjalte" in the film), and caressing a blurry image of Elisabet and/or Alma's faces.A young nurse, Alma (portrayed by Bibi Andersson), is summoned by the head doctor and charged with the care of stage actress Elisabet Vogler (portrayed by Liv Ullmann), who has, despite the lack of any diagnosed impairment, become mute. The hospital administrator (portrayed by Margaretha Krook) offers her own seaside cottage as a place for Alma to nurse Elisabet back to health. Though Elisabet is nearly catatonic when the film begins, she does react with extreme panic upon seeing a Vietnamese Buddhist monk's self-immolation on television, and laughs mockingly at Alma's radio soap opera. As the two women leave the hospital together, Alma reads aloud a letter Elisabet's husband has sent her, which includes a photograph of her young son.Together in the administrator's cottage, Elisabet begins to relax, though she remains completely silent and non-responsive. Alma speaks constantly to break the silence, at first about books she is reading and trivial matters, then increasingly about her own anxieties and relationship with her fiance, Karl-Henrik, who scolds her for lacking ambition "though not with my career, I suppose in some greater way." Alma constantly compares herself to Elisabet and begins to grow attached to her. As the act closes, Alma confesses to cheating on her fiance in a menage a quatre with underage boys. She became pregnant, and had Karl-Henrik's friend abort the baby; "and that was that". She is not sure how to...

Question: Why did Oak hide Calvess'suicide?

Eighteen months later, the Detroit Police Department asks Tellis to investigate the murder of an undercover narcotics officer called Michael Calvess. Tellis is initially reluctant, as there is little else he can do for a living however, he reads the investigation files and agrees to take the case, on two conditions. The first: he will get a desk job if he secures a conviction. The second: he is partnered with detective Henry Oak (Ray Liotta), whom Tellis is aware of through reading the files on Calvess' death. Tellis' reason for wanting Oak is his opinion that the only useful evidence in the investigation came from him.

Title: 30 Days of Night Movie plot: Barrow, Alaska, is preparing for its annual "30 Days of Night", a period during the winter when there is a month-long polar night. As the town gets ready, a stranger (Ben Foster) rows ashore from a large ship and sabotages the town's communications and transport to the outside world. Barrow's sheriff, Eben Oleson (Josh Hartnett) investigates and also learns that his estranged wife, Stella (Melissa George), missed the last plane and must stay the 30 days. That night, a coven of feral vampires, led by Marlow (Danny Huston), attack and slaughter most of the townspeople, forcing Eben, Stella, Eben's younger brother Jake (Mark Rendall), and several other survivors to take shelter in a boarded-up house with a hidden attic. Marlow finds the stranger locked up in the station. The stranger believed Marlow was going to turn him into a vampire. Marlow thanks him for doing what he asked, and then snaps his neck. Marlow comments to his fellow vampires "What lies they will believe." Eighteen days later, when a blizzard hits, the group uses the whiteout to go to the general store for supplies, but are stranded after it ends. While the group heads for the station, Eben creates a diversion by having the vampires chase him to his grandmother's house, where he uses one of her ultraviolet lights to burn the face of Marlow's lover, Iris (Megan Franich), so badly that Marlow is forced to kill her.
