MTV News chatted with the Source Code star about his fascination with the complicated plot of the film.

"First, I was just fascinated with the idea, the concept of what the Source Code was because it felt like the center of the movie is this computer program," Jake explained. "So I thought, 'Well, does this hold water?' And then I thought, 'It does because it's a computer program that allows somebody to go into the body of another person for the last eight minutes of their life.' Had it been a computer program that allows somebody to go into somebody else's body, just anybody's body, it wouldn't be interesting, but this plays on the usurping of the electromagnetic impulses in the brain right before somebody dies."

And he hopes that the audience walks away feeling the same way he did — ready to debate!

"It opened up a world of possibilities, philosophically, for me," he said. "And psychologically, what effect does this have on the human brain, the person experiencing it, but at the same time, what effect could it have on history and what could it be used for? It was just fascinating: There are a million ideas that come out of it."
