In the movie Trial by Jury, there is a scene on a street, where Joanne Whalley Kilmer is talking to William Hurt. There is a small number of people on this street walking pass them. As she is speaking there is a person who is behind her, he is walking towards them. He is wearing a sports coat with a black sweater under the coat. She then walks past William Hurt, turns back to respond to something he said. Now her back is in the opposite direction, and the same man is walking behind her with the same clothes. How in one second can he be walking towards them again, from the opposite direction. Obviously an extra was used, and they must have stopped filming, and now he's coming from another direction. On film it's only a matter of a second or two.
