Corpse Eaters (1974)

On Friday the 13th, two young couples go to a cemetery. When it starts to rain, the couples go into a open vault to stay dry. There, they play a game with a satanic ritual which awakens the dead — with disastrous results! Stars Michael Hopkins, Ed LeBreton and Terry London.

Corpse Eaters premiered at Lawrence Zazalenchuk's drive-in, theater, “The 69 Drive-In.” The film had a long run until a New York distributor purchased the film and later shelved it into obscurity as a tax write-off.
