Prisoner in the Mirror

Lloyd Bochner stars as Professor Harry Langham, who is obsessed with learning more about a mysterious magician and rumored sorcerer Count Cagliostro, who lived in Paris, where Harry discovers a painted-over mirror that once belonged to the count, and was considered most important to him. Harry has it sent back to his home in America, where he scrapes the paint off it, and discovers that the count(played by Henry Daniell) inhabits it with a beautiful young woman named Yvette(played by Pat Michon) and intends on taking over his body so that he will live again, while Harry is trapped behind the mirror with Yvette... Eerie premise is well handled here, though low budget limits what can be done visually, leaving the mirror world a bit vague, but a fitting finale makes up for it(though leaves a pair of loose ends...)
