The Hitchcock classic, Psycho, is about a woman staying at a rural hotel being watched by the innkeeper. 

While in the infamous shower scene, the woman played by Janet Leigh is slashed to death. 

On set, one of her stand-ins was Myra Davis, a working actress. 

Years later, Myra Davis was raped and murdered by a handyman who also turned out to be a huge Hitchcock fan.
