Dementia 13 (1963)
Directed by Francis Ford Coppola and produced by Roger Corman, Dementia 13 is the story of a greedy young woman who marries into money, but stands to loose it all when her husband dies. Not wanting to miss out, she covers up his death and sets about trying to soft-soap her mother-in-law into writing a new will. You can find out more about Dementia 13 at A Passion For Horror.
