This one is way, way up there on the silly meter--and it has the distinction of being the second film directed by Oliver Stone. This bizarre and unintentionally funny horror film deals with a cartoonist (Michael Caine) who has drinking and marital problems; both are exacerbated when he loses his hand in a car crash. But that seems like child's play compared to his real troubles: the severed hand, which was never recovered, takes on a life of its own and starts killing everyone who makes Caine angry. The hand lacks the dexterity of the Addams family's Thing but, otherwise, it's just as funny.
