Try renting Shadow of the Vampire with John Malkovitch. It is all about the making of Nosferatu and explains some of the weird crap that went on while making it. The actor that played the vampire was a real nut. All of what the movie says IS NOT TRUE, but i know some of it was. It explains why the ending of it was so quick and bad. Again, not true, but made for a cool movie, especially since you just watched Nosferatu. Hope you like it.
