Homicidal

Homicidal represents producer/director William Castle's slant on Hitchcock's Psycho. The film concerns a young woman named Miriam Webster (Patricia Breslin) who seemingly has everything a girl could want - including a successful flower shop business, and a handsome beau, Karl (Glenn Corbett), who works as a pharmacist. Events take a turn for the worse, however, when Miriam's half-brother, Warren, returns from Europe - with a rather unpleasant friend in-tow: a blonde named Emily (Jean Arless). Emily promptly sets about destroying Miriam's life: the newcomer attempts to wheedle Karl away from Miriam, then rips the flower shop to pieces, then ultimately reveals a little taste for knife-wielding that directly threatens Miriam's safety. Like The Tingler and other Castle outings, this one originally featured a gimmick, preserved in the video release: a "fright-break" just prior to the climax, which allowed terrified audience members approximately 45 seconds to get out of their seats and leave the theater - to avoid the prospect of being "frightened to death."
