Foil was one of the many literary features I found in this film. Francis Ford Coppola portrays foil in the Godfather in one scene where the 3 brothers Tom Hagen, Micheal, and Santino are discussing about a plan. The plan was to figure out how to kill Sollozzo and the Police Chief in a spot where no one would find out. The room arrangement where everyone was sitting was in a way that shows how Micheal has a part of Tom and Santino inside of him. Francis expresses Tom's intelligent side inside Micheal because in the story when they were discussing about the plan Micheal was thinking about everything step by step. Micheal also thinks before he acts like Tom. For example how to get out without anyone knowing he killed them, what the locations should be and more. Micheal's aggressive and ruthless side comes from his other brother Santino. In the story Micheal shows that when they were talking about how to get rid of the problem and Micheal just suggests to kill both of them.
This image below shows the room arrangement in which the 3 brothers were in. As you can see Micheal is in between them.
