"He could control other people's minds; see what happens when a beautiful girl enters his life."
Phony spiritualists were given a good going-over in the early talkie melodrama Darkened Rooms. Evelyn Brent stars as Ellen, a fraudulent medium working in cahoots with genuine clairvoyant Emory Jago (Neil Hamilton). The plotline is secondary; the film's main purpose was to emulate the methods of such professional "de-bunkers" as Mrs. Harry Houdini by exposing the various tricks of the spiritualist's trade.
