I think THE BLACK PIT OF DR. M/MISTERIOS DE ULTRATUMBA, is one of the best gothic horror films of the fifties and early sixties. It's got everything I want in a horror movie---supernatural goings on, madwoman splashing a guy in the face with acid, transmigration of the soul, disfigured corpse rising from the dead, ghosts. You name it, it's in there, skillfully directed and acted, and dripping with weird atmosphere.
