Bullet Train is an American action comedy that pits various killers against each other while riding a bullet train. In this scene, Lemon has tracked down two people (Prince and Kimura) and needs information. Instead of torturing the two of them, he opts instead to place them in a classic prisoner’s dilemma. He hopes that the two will be self-interested and reveal the outcome he desires.
Prince and Kimura are asked to close their eyes and either confess or rat the other person out. Lemon reminds them that cooperation (both raising hands or both pointing at each other) is likely a lie and he will kill them both. It’s a slight twist on the traditional prisoner’s dilemma played in classrooms, but it’s nice to see an application of interdependence and game theory in movies.
