In most of Kubrick's movies, he includes a shot where an actor facing the camera has his head bent forward and he is looking at the camera out of the "tops" of his eyes. It usually looks pretty creepy. In the opening shot of "A Clockwork Orange" Malcom McDowell is doing this while the camera backs away from him during the opening narration. (He also does this later in the movie while reading a bible.) Jack Nicholson is actually frozen into this pose in the topiary maze at the end of "The Shining." The psycho boot camp Marine recruit does this in "Full Metal Jacket" just before he shoots the sadistic sargeant. I can't take credit for this-- Roger Ebert mentioned it at the end of a recent "At the Movies" episode solely dedicated to reviewing "Eyes Wide Shut." Tom Cruise does the same thing in THAT movie, by the way...
