Luke Nutter's film studies presentation compares the narratives of Mr. Nobody and Source Code. Source Code follows a protagonist used in a military program to help solve a train bombing through simulations, while Mr. Nobody depicts the life of a man and the effects of his choices. Both films show characters overcoming problems, with lessons about not changing the past but learning from it, and how small decisions impact one's life. The audience is left questioning the nature of reality and existence from Mr. Nobody and the morality of manipulating the protagonist in Source Code.
