Hallucinations of a Deranged Mind (1978)

This movie is basically a vehicle for recycling footage from the eccentric pantheon of Brazil's premier horror filmmaker Jose Mojica Marins, whose own persona often melds with that of his popular alter-ego "Coffin Joe". Clips are culled from the trademark surreal nightmare sequences favored by Marins in such films as Esta Noite Encarnarei No Teu Cadaver (Tonight I'll Be Incarnated in Your Corpse), Ritual dos Sadicos (Ritual of the Maniacs) and Exorcismo Negro (Black Exorcism). These grotesque, hallucinatory set pieces are depicted as the nightmares plaguing psychologist Dr. Hamilton, who is haunted by the character of Coffin Joe. In an effort to stop the dreams, Hamilton seeks the aid of Joe's creator (Marins, as himself), who tries to convince him that Joe is not an actual demon but a flamboyant character he intends to lampoon in his latest film.
