Let’s remember that the well-known shot in Jaws (starting at 3:35) of Roy Scheider peeking out at the water over the shoulder of some guy he’s talking to is a steal from Alfred Hitchcock‘s I Confess. I’m speaking of a shot of Karl Malden peeking over the shoulder of a guy he’s conferring with in order to check out Montgomery Clift, who’s standing on a sidewalk a few yards away.
There’s nothing wrong with theft, mind. The greatest poets have done it, or so said T.S. Eliot.
