McKee uses the scene from Star Wars where Darth Vader tells his son Luke Skywalker for the first time that he is his Father ('You can't kill me (...) I am your Father') as an example of how this sudden rush of insight - not only for Luke but also for the audience - sends the spectator straight back to the start of two whole movies. One has to revise its view and perspective over everything one saw during two movies of Star Wars to comprehend and digest the story again. It all makes sense. Again. What other movies do you know with such powerful revelation that it causes such a sudden rush of insight?
