Teenage Monster is an independent science fiction, horror film, premiered December 25, 1957 and released by Marquette Productions Limited in 1958.
Directed by Jacques R. Marquette, the film starred Anne Gwynne and Stuart Wade. The film combined the elements of science fiction and westerns, both of which were popular in the late 1950s. It also continued to use the word "teenage" in the title, a trend that was common in motion picture titles, including I Was a Teenage Frankenstein, and I Was a Teenage Werewolf. The film's alternative titles were Meteor Monster and Monster on the Hill.
The story is set in a town in the American Southwest. Young Charles Cannon (Stephen Parker), after seeing a meteor crash in the desert heads out to investigate it. He becomes exposed to rays from the meteor and ages rapidly. He is now about ten years older, hairy, aggressive, and psychopathic. His mother hides him in the basement to protect him from the law.
