I, Monster (DVD)

In this adaptation of the 1886 story "Strange Case of Dr. Jekyll and Mr. Hyde," psychologist Charles Marlowe (Christopher Lee) invents a drug that helps release the inhibitions of his patients. But when he tests it on himself, the concoction reveals a different side of Marlowe - an evil side named Edward Blake who spirals into a life of crime and, eventually, murder. His friend Frederick Utterson (Peter Cushing) suspects when grisly killings take place.

Starring: Christopher Lee, Peter Cushing, Mike Raven, Richard Hurndall, George Merritt, Kenneth J. Warren, Susan Jameson, Marjie Lawrence, Aimée Delamain, Michael Des Barres
