In the scene in which Bela Lugosi is hit by a car, you will note that he walks across the lawn out of sight, and then you hear the screeching sound of a wreck. Poor Bela...

Only one problem: you can see his shadow the entire time. He stopped walking as soon as he was out of the scene.

It is almost unfair to pick on a movie this flawed, but that was always one of my favorite screw-ups.
