Parapsycho – Spectrum of Fear

Parapsycho – Spectrum of Fear is a 1975 Austrian horror film directed by Peter Patzak, starring Marisa Mell, Leon Askin and Debra Berger. Split into three episodes, it uses extrasensory perception, reincarnation and telepathy as its subject matter. Even in the school of New German Cinema, the film was ground-breaking for using footage of a real autopsy, beginning with the incision of the body from sternum to pubic bone, rather than recreating the scene using prosthetics or special effects.
