BLACK PIT OF DR. M (1959) - Used DVD

Like new! Never played, just no shrink wrap. This could also be titled: All Heck Breaks Loose at the Asylum. There's weird experiments with life and death (moonlighting by the hospital doctors). A ghost-zombie of a dead--subject. An inmate splashes acid on a hospital employee's face and he become hideously scarred (and homicidal). It sounds like a crazy mix (and it is), but it's filmed with much shadow, darkness and atmosphere. Very, very creepy. A south-of-the-border spook show. One of the very best horror films from Mexico in the 1950s-1960s. IN SPANISH, with optional English subtitles.
