In an interview with Roger Ebert and in the book Alfred Hitchcock and the Making of Psycho, Leigh stated she was in the scene the entire time and Hitchcock used a stand-in only for the sequence in which Norman wraps Marion's body in a shower curtain and places it in the trunk of her car.
Međutim u intervjuu s Rogerom Ebertom kao i u knjizi Alfred Hitchcock and the Making of Psycho Leigh je naglasila da se upravo ona nalazi u sceni cijelo vrijeme; Hitchcock je koristio drugu glumicu samo za scene u kojima Norman omotava Marionino tijelo sa zavjesom tuša i stavlja ga u gepek automobila.
