Hideous Sun Demon (1959)
Dr. Gilbert McKenna (Robert Clarke, 1920–2005) is an atomic scientist and an alcoholic. In his laboratory he accidentally exposes himself to a large dose of radiation. The effect of this exposure is catastrophic as he becomes the murderous and lizard-like “hideous sun demon” whenever exposed to light. The movie is a cult classic and marks the directorial debut of Robert Clarke, a popular star of many of the best science fiction films of the 1950s. Clarke wrote, directed, and produced the film.
