In a scene from the movie Manhattan Murder Mystery, Woody Allen and Diane Keaton are at a hockey game in Madison Square Garden. She is ob- viously not enjoying herself, but he tells her: “Remember our deal. You stay here with me for the entire hockey game, and next week I will come to the opera with you and stay until the end.” Later, we see them com- ing out of the Met into the deserted Lincoln Center Plaza while inside the music is still playing. Keaton is visibly upset: “What about our deal? I stayed to the end of the hockey game, and so you were supposed to stay till the end of the opera.” Allen answers: “You know I can’t listen to too much Wagner. At the end of the first act, I already felt the urge to invade Poland.” Comment on the strategic choices made here by using your knowledge of the theory of strategic moves and credibility.
