How did you feel when approached to do a movie about Facebook? Did you all cringe and think of other geek related movies and how they usually bombed?

Andew Garfield: I think I had the reaction that most people have, which is that a movie about Facebook sounds really boring, and then immediately after that, my lack of imagination was made very clear to me when I saw the script that Aaron Sorkin had written.

I had no idea that there was such turmoil and turbulence and excitement - just an interesting situation surrounding the inception of the website. So, of course, after having read the first 10 pages or so of the script, I was just like, 'This is a work of real, amazing art.’

I was incredibly excited to be a part of it, and from that point on I had no doubt that it was going to be a film that was going to be really fun to do.

Justin Timberlake: I think our introduction to the film was the fact that we were going to be reading an Aaron Sorkin screenplay, so the answer's 'no'. I think if I'm maybe 5% more adept to what Facebook is now; I was completely ignorant before. I got sent the screenplay and said 'Yeah' to the script Aaron Sorkin wrote, I believe they said was about Facebook, but I didn't hear that part weirdly enough.

But I think they said Fincher's going to be directing it, and so I just... immediately going into it, you knew that whatever it's going to be, it's going to have a high level of integrity and intelligence and class.

And so, what I found was not a story about Facebook at all, but a more  story about youth and friendship and betrayal the way that Aaron writes is much like a playwright; very Greek in its structure. Hard to read though, because I don't know Greek.

Jesse Eisenberg: I heard they were making a movie about Facebook, and thought that was a strange idea for a movie, you know, how interesting could that possibly be?

Then, like Justin, I heard that Aaron Sorkin was going to be writing it, and thought this must very special, and that David Fincher was going to direct it, so I thought there must be something else. So it's not only a very special story, but something that could be the backdrop for a very interesting aesthetic, like David Fincher likes to bring to all his movies.

And when I read the script, I thought: 'This is perfectly Aaron Sorkin.' It perfectly reflected everything I loved about Aaron Sorkin - the clever dialogue, very interesting characters, raises kind of, contemporary issues, and there basically no easy answers.

I wondered how David Fincher's could bring his kind of visual style to the movie and didn't know what that would be until I saw it last week, and he created a very unsettling tone to the whole thing.

When the characters are creating Facebook, and it's this very kind of exciting feeling, and it feels young and fresh and new and inspired and then when justin comes in, Justin brings that real kind of danger to it, the dark side of early success.
