Did you happen to notice this amazing shot in Alfred Hitchcock's Psycho? As the private detective so called Arbogast tries to worm out information from him, Norman Bates starts to chew his peanuts quicker while looking at the motel registration book. And Hitchcock's camera slowly slides along his throat and just clings to his Adam's apple. As an angry dog. Then a black form suddenly starts to shake its wings as one of these stuffed birds hung on the walls. Hitchcock couldn't have forgotten about those anamorphoses you find at the bottom of some crazy paintings, hidden like obscene secrets from quick innocent glances. Indeed, to such a sexual perv as Hitch, what could be more obscene that Anthony Perkins's Adam's apple?
