 The scene at the beginning with Captain Willard alone in his hotel  room was completely unscripted. It was the last scene to be shot,  and Martin Sheen (qv) told the shooting crew to just let the  cameras roll. The crew was so disturbed by his actions, such as  punching the mirror, then rubbing the fresh blood on his face that  they wanted to stop shooting, but director  Francis Ford Coppola (qv) wanted to keep the cameras going.
