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.

input: Please answer the following: Generate a question that has the following answer: A mysterious, masked man for the following movie plot: On the Berlin subway, university student Cheryl gets off at her stop in the deserted subway station and is pursued by a mysterious, masked man. Rather than attacking her, the man offers her tickets to a free screening at the Metropol, an isolated and recently renovated local cinema. Cheryl talks her friend Kathy into going with her and they skip class to go see the film. At the crowded theater, they meet two preppy college boys, George and Ken, who take an immediate liking to the girls and help them get a can of cola out of the vending machine. The four sit together in the theater. There are many people from all walks of life in the audience; a blind man and his guide daughter; an elderly married couple; a boyfriend and girlfriend; and a pimp named Tony along with his two prostitutes, who look at the theater's display props in the foyer. One of the prostitutes, Rosemary, scratches her face with a bizarre display mask before they go in to watch the film. The film is a violent, disturbing horror movie which features a look-alike of the mask from the lobby. It is about four teenagers who discover an old tomb and dig up the grave of a sixteenth-century fortune teller called Nostradamus. When the teenagers dig up Nostradamus's coffin they find no body, just an old book and a mask identical to the strange mask in the foyer. When one of the characters puts the mask on he's scratched by it just like Rosemary was by its doppelganger. A moment later, he turns evil and slaughters his friends with a knife. Rosemary feels ill and goes to the bathroom, where the scratch on her face bursts open, spewing out pus. She is soon transformed into a bloodthirsty, green-skinned, red-eyed, fanged demon like the one in the film. Rosemary attacks her friend, Carmen, who then rips through the screen and transforms into a demon in front of the rest of the cinema-goers. The group of uninfected people race to any exit they can find, only to find that they have all been bricked up making escape impossible. Although they attempt to...

In this post-nuclear society, Caesar tries to cultivate peace between the apes and the surviving humans. A gorilla general named Aldo (Claude Akins) however opposes this and plots Caesar's downfall. Caesar is married to Lisa (Natalie Trundy), the female ape of the previous film, and they have a son named Cornelius (Bobby Porter) in honor of Caesar's father.
