The Devil Inside TV and Film

Louis Cyphre, "Angel Heart"

Bad boy, bad boy, whatcha gonna do?: Hire a New York P.I. to find a singer named Johnny Favorite, who is really the very same P.I. who tried to escape having to give up his soul. And proceed to make that P.I. kill people, including his daughter/lover, as he searches for something he can't find. Twisted, right?
