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 obviously 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 coming 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.
