Doctor Blood’s Coffin is a 1961 British horror film produced by George Fowler, and directed by Sidney J. Furie. It stars Kieron Moore, Hazel Court and Ian Hunter. People are mysteriously disappearing near a remote Cornish village, where a scientist is experimenting with reviving the dead.
A merchant marine seaman is found murdered and suspicion falls upon the operator of a dime-a-dance honky tonk joint. A federal undercover agent is planted in the place to gather evidence, and he soon learns that the dive is only a cover-up for diamond-smuggling activities, and that one of the operation’s henchmen, who is handy with a switch-blade knife, is the killer. Before they can be arrested, the henchman kills his boss and is shot while trying to escape.
