The Devil's Sleep is a 1949 exploitation film directed by W. Merle Connell and produced by George Weiss. Connell had previously directed a number of American burlesque films. The film looks at juvenile delinquency, phony women's health gyms, and the pushing of narcotics to teenagers. Using many of the same cast and crew as Test Tube Babies, the film is the first of Timothy Farrell's "Umberto Scalli" trilogy.
