Descargar Anguish (1987)

This gruesome horror film is about a mother-fixated ophthalmologist's assistant with an unhealthy interest in eyeballs and goes on a killing spree to collect human eyeballs for his mother's collection. But this is all just a horror movie viewed by a small crowd where a very real killer in the audience begins killing the patrons one by one paralleling the action in the other movie.—Nick Wilson
