After exposure to radiation, a hard-drinking atomic research scientist (the film's writer, director, and lead actor Robert Clarke) finds himself changing into a murderous, hideous, lizard-like creature whenever he is exposed to the sun. This classic B movie from 1958 also stars Marilyn Monroe–lookalike Nan Peterson as a singer he meets when he fatefully wanders into a bar one night. Some have called his transformation a veiled metaphor for the ravages of alcoholism. The DVD includes personal recollections by Clarke.

"I must confess that I enjoy Demon. Its naivete is a more reliable pathway to wonder than the cynicism and condescension of contemporary fantasy films could ever be."—San Francisco Chronicle
