Justin, was it harder or easier playing a real person in The Social Network or Alpha Dog?

JT: The application's kind of similar. I actually, in the process of making Alpha Dog, did meet the guy my character's based on to ask him questions and do a little bit of research. And in this instance, I ironically met Sean Parker, but before I was cast in the film.

But yeah, I think in both cases you feel a sensitivity to knowing that you're playing someone who sort of is still walking the Earth.

Where it differed in Alpha Dog was there was a pretty clear cut court case that led to someone's sentencing. So it's pretty clear what happened, which is a tragic story. And then in this, what became, I think, more intriguing to Aaron Sorkin as a screenwriter, is that when he researched the story, everyone had a different story, their own version of the story, and he felt it was his job to include the opposition in this movie.

I think that in dealing with the subject matter on this film, it's the same application, where you just feel sensitive to it, but like we've said in numerous interviews, Aaron researched this material with an overwhelming amount of specificity and accuracy and integrity.

One, because I think he felt morally obligated to, like Jesse said, it's not the easiest thing to have a movie about your life at 19 and for two years of time, be depicted into a feature film. And also he was legally obligated to not write anything that was defamatory, so obviously there's going to be opposing opinions on the ways some things happened. But I find that to be very human and life-like and I think it was very smart for Aaron to embrace that.
