Eegah

"Considered one of the worst films ever made, Eegah! is the story of a gigantic Neanderthal who has managed to survive into modern times living in California's Mojave desert, and who falls in love with and kidnaps the teenage girl who discovered him in a cave. A handsome young man (Arch Hall, Jr., the director's teenage son) proves to be her savior and while he and his rock & roll band play, the police shoot the caveman to bits."
