Fernando Mendez started his career as a feature film director in 1940, Arch. He directed many films, including LADRON DE CADAVERES (BODY SNATCHERS), the first wrestling monster movie I'm aware of. The still from LADRON of the drooling gorilla man was often shown in FAMOUS MONSTERS back in the day. Mendez also directed EL VAMPIRO (THE VAMPIRE), EL ATAUD DEL VAMPIRO (THE VAMPIRE'S COFFIN), and EL GRITO DE LA MUERTO (THE LIVING COFFIN), as well as MISTERIOS DE ULTRATUMBA (BLACK PIT OF DR. M), and films in other genres. He died in 1966 at the age of 57 or 58.
