Trivia: Although released to theatres in 1966, this beautifully-shot film was actually the pilot for an unrealised television series entitled "House of Wax" (which was never picked up by the networks). Despite its title, "Chamber of Horrors" was not particularly scary, much less horrifying; in fact, it was more like a 19th Century crime-detective drama. After the TV pilot was rejected, Warner Brothers opted for a theatrical release, even though the film was shot in television screen format rather than wide screen format. Attempting to sensationalize "Chamber of Horrors" for the big screen, Warner Brothers added the preposterous "Fear Flasher and Horror Horn" gimmick to warn audiences of imminent violence and gore...except that there was no gore and practically no onscreen violence.
