Leit motif: This ‘reiteration of theme’ involves repeating a shot or sequence at key moments as a sort of code. Think how Spielberg uses a ‘point of view’ shot in Jaws showing the shark looking up at swimmers. The first time he does it creates a visual code for “the shark’s about to attack”. Every time we see that underwater POV we know an attack is imminent. He has allowed us to participate in the decoding.
