Chamber of Horrors

Chamber of Horrors (1966)

A madman forces a priest to complete a wedding ceremony with a corpse, then goes into hiding at a brothel where he orders women to lie very still - more explicit  shades of necrophilia here than the hints in the Poe based film this draws from.

To escape police custody, the madman chops his hand off with a hatchet.  Underwater.  He then seeks revenge, using different deadly accessories on his stump.  Amateur detectives associated with a wax museum investigate.

Originally a pilot film for TV series, it was padded out to be released theatrically.  It has William Castle style gimmicks, such as the Fear Flasher and Horror Horn to warn of impending implied off-screen violence.
