Basket Case is a 1982 American horror comedy film written and directed by Frank Henenlotter. It has two sequels, Basket Case1990 and Basket CaseThe Progeny 1991 by the same director. It is notable for its low budget, bizarre humor, and strong violence. The film gained an audience in the 1980s due to the advent of home video and has become a cult film. Kevin Van Hentenryck stars as a normallooking person who seeks vengeance for the unwanted surgery that separated him from his deformed Siamese twin brother.
Basket Case was shot on 16mm film. Director Henenlotter did not have control over the postproduction, and the result was dark, murky, and converted to a different aspect ratio. The film was shot in part on Manhattans 42nd Street. Henenlotter wrote the film as he walked around Times Square, which he called a seedy, wonderful atmosphere.The special effects for Belial consist largely of a puppet in some scenes and stop motion in others. When Belials hand is seen attacking his victims, it is really a glove worn by Henenlotter. The full size Belial puppet is also seen in the scenes where Belial is seen with an actor or where his eyes glow red. The Belial rampage sequence used stop motion animation. ........
