This film about a momma's boy psycho killer who collects his victims eyeballs turns out to be a movie-within-a-movie. A "real" killer is loose in the theater and preying upon those watching the film. An extremely imaginative horror film from Spain. Mom is played by Zelda Rubinstein, the annoying diminutive actress who portrayed the medium in Poltergeist. The soundtrack supposedly features subliminal effects.
