An urban legend has it that Leigh's screams in the famous Psycho shower scene were prompted by Hitchcock shocking her with cold shower water. Leigh denied this in her memoir, insisting that Hitchcock kept the water warm and comfortable, as the sequence took a whole week to shoot. Hitchcock used Playboy model Marti Renfro as a nude body double for Leigh in some shots. Leigh was never nude as some believe. To create the sound effect of the knife stabbing flesh, Hitchcock experimented on watermelons, casabas, cantaloupes and honeydews. Hitch settled on the Casaba.
We now know that Hitch never watched any of his films as they were "too scary". Here are some other pieces of trivia about the Master of Suspense. He had a lifelong fear of the police stemming back to an incident in his childhood when his strict father punished him by sending him to the local police station near his east London home. He rarely ate breakfast and never anything containing eggs as he calls them "fritening and revolting". He is far from self tutored.. leaning much of his craft from German expressionist filmmaker F.W. Murnau, who created the chilling Dracula adaptation Nosferatu. “From Murnau,” Hitchcock later said, “I learned how to tell a story without words.”

Alfred Hitchcock Explains the Plot Device He Called the ‘MacGuffin’ "Perhaps the most important thing to remember about the MacGuffin is that it contains the word "guff," which means a load of nonsense. There's a lot to look for in Hitchcock's films, but watch out for the MacGuffin. It will lead you nowhere."
