Chamber of Horrors (Blu-ray)

This dull HOUSE OF WAX variant involves a claw-handed escaped maniac (Patrick O'Neal), who rampages through late 19th-century Baltimore on a mission of vengeance. Hot on his trail are the proprietors of a "House of Horrors" wax museum and their Mexican dwarf sidekick Tun-Tun. Initially conceived as a TV movie, this tepid horror-thriller was instead spiced up with additional gore and violence for theatrical release. Apparently this was still not enough, as the producers then decided to add a few William Castle-type gimmicks -- the "Fear Flasher" and "Horror Horn" -- to prepare audiences for upcoming bouts of onscreen bloodletting. Unfortunately, no such device was employed to warn viewers of imminent boredom.
