Jack Frost is an American horror comedy film written and directed by Michael Cooney and released in 1997. The movie takes place in the fictional town of Snowmonton, where (on the week before Christmas) a truck carrying serial killer Jack Frost (Scott MacDonald) to his execution crashes into a genetics truck. The genetic material causes Jack's body to mutate and fuse together with the snow on the ground. Jack is presumed dead and his body melts away. However, he comes back as a killer snowman and takes revenge on the man who finally caught him, Sheriff Sam Tiler (Christopher Allport). The film has since become a cult classic.
