Horsehead was in the first one. Because the movie director denyed Don's request of getting his godson or something (The name slips me) to star in the movie.
Also, I've seen Jaws, it just never made that great an impact on me. I mean, it's good but I live in an area where the only sharks are the kind you can keep in a small fishtank.
Nosferatu is hilarious. I think it's the eyebrows, or the way he walks. It's a bit creepy though after reading Dracula by Bram Stoker, but not that much. The scene where he's going up the steps and you can see his long "talons" freaks me out.
