For his feature film debut, director Peter Maris took portions of an unfinished conspiracy thriller and added a new psycho-killer procedural to create DELIRIUM—one of the most unusual proto-slasher shockers of the 1970s. When a series of savage murders rocks St. Louis, the police investigation will lead to a deranged Vietnam vet, an underground organization of white-collar vigilantes, gratuitous nudity, and graphic violence. An absolute masterclass in low-budget regional filmmaking, DELIRIUM has been preserved from the only known 35mm print in existence.
