Todorov's Theory in Due Date

http://www.youtube.com/watch?v=gf2AfVESbx0

Todorov's theory was that at the beginning of a narrative something would happen to disrupt the state of equilibrium of the main character. The story would then show the struggle of the main character to get back to normal. This is true in the case of Due Date because the main character, Peter, is about to return home where his wife is about to have their child which would normally be simple. However, he meets Ethan who gets him kicked off the plane and they ultimately have to journey together to get to LA which Ethan doesn't make easy for Peter. In the end they reach LA in time for Peter to be there for the delivery of his child, Peter and Ethan become friends and in the last scene Ethan is shown having achieved his dream of becoming an actor and Peter is with his family.
