One shocking fact I learned today about the film: In the scene where DiCaprio saws open the skull of his old family servant (supposedly to show the genetic inferiority of the black man), I was left wondering why his left hand was bleeding all over the place. Turns out he actually DID accidentally cut his own hand open with the saw (it wasn't in the script), and he just went with it in a paroxysm of method acting that so impressed QT he used that take in the film (yes, Kerry Washington got an unexpected faceful of REAL Leo blood).
