Dementia 13, released on November 18, 1966, is a film directed renowned director Francis Ford Coppola, of The Godfather films, and produced by horror veteran Roger Corman. The movie, made on a low budget, was Coppola's first major mainstream project and starred B movie actor William Campbell and Luana Anders and Patrick Magee.

Dementia 13, set in a castle in Ireland, tells the story of the Haloran family. Lady Haloran, whose daughter Kathleen died in a drowning accident seven years ago, makes regular visits to her grave as part of a tradition. In her will, she has stated that everything must go to charity in Kathleen's honor, to the resentment of her son John and his wife Louise. If John dies, he receives no money. Unfortunately, he dies of a heart attack while he and Louise are out boating. Louise, unwilling to lose the inheritance, hides the body and visits her mother-in-law. Once she gets to the castle, things take a turn for the scarier when a mysterious axe murderer shows up.
