Teenage Monster (1957)

Synopsis
A meteor crashes somewhere in the West, killing a miner named Cannon (Jim McCullough). The miner's son Charles (Stephen Parker) survives the ordeal, but grows into a hairy, bestial moron, given to killing sheep, cattle and stray humans. Charles is protected by his long-suffering mother Ruth (Anne Gwynne), who does her best to clean up her son's messes. When mercenary waitress Kathy (Gloria Castillo) learns of Charles' existence, she blackmails Ruth to secure her silence. Kathy also goads Charles into killing a few of her own enemies, leading him on by pretending to be in love with him (a BIG mistake!) Originally (and subsequently) titled Meteor Monster, this tacky little sci-fier was originally released on a double bill with The Brain From Planet Arous. ~ Hal Erickson, All Movie Guide
