I'm not sure if this has ever been mentioned, but I thought I'd throw it out there. I just bought Alred Hitchock's "Psycho" on dvd, and I was watching the documentary on the making of the movie that is part of the bonus features. Anyway, they are talking to janet Leigh, and she is talking about the filming of the shower scene. She is discussing the one shot where she is laying on the floor, perfectly still, and the camera has an extreme close-up of her eye, and it kind of rotates and pulls back. So she's talking about how difficult it was to stay still and not blink, and she says something along the lines of "The water was dripping down the side of my face, and it is hard to not blink, because it tickles. It's like an itch you can't scratch." Now, it isn't really the kind of tickling we love here on the TMF, but hey, it works for me!
