I'm going with what's been reported to be Fincher's favorite piece of dialogue: Gretchen: 18,000 dollars? Eduardo Saverin: Yes. Gretchen: In addition to the $1,000 you'd already put up? Eduardo Saverin: Yes. Gretchen: A total of $19,000 now? Eduardo Saverin: Yes. Mark Zuckerberg: Hang on. [Mark sarcastically adds up the 2 amounts on his notepad] Mark Zuckerberg: I'm just checking your math on that. Yes, I got the same thing.

There are SO many memorable lines in this script. The one Vic noted is Z perhaps at his snarkiest-in-brief. But I'm going to go in another direction and post this as my favorite exchange, not Zuckerberg, not Eduardo, not Sean Parker, but the twins: Cameron Winklevoss: What, do you want to hire an IP lawyer and sue him? Divya Narendra: No, I want to hire the Sopranos to beat the shit out of him with a hammer! Tyler Winklevoss: We don't even have to do that. Cameron Winklevoss: That's right. Tyler Winklevoss: We can do that ourselves. I'm 6'5", 220, and there's two of me. "I'm 6'5", 220, and there's two of me". That is pure awesomeness! Made all the more so because these two guys are self-serious to the max, making this line completely unexpected.

I absolutely dig that line. It's my single favorite line in the whole thing.

I'm definitely with Vic and Scott on their picks, but I also love the dialogue in the opening scene between Mark & Erica. Rooney Mara and Jesse Eisenberg really brought that to life. Specifically, when she tells him she's going to leave: Erica Albright: I'm going back to my dorm. Mark Zuckerberg: Wait, wait! Is this real? Erica Albright: Yes! Mark Zuckerberg: Okay, then wait. I apologize, okay? Erica Albright: I have to go study. Mark Zuckerberg: Erica... Erica Albright: [Harsh and angry] Yes? Mark Zuckerberg: I'm sorry, I mean it. Erica Albright: I appreciate that, but I have to go study. Mark Zuckerberg: Come on, you don't have to study, you don't have to study, let's just talk. Erica Albright: I can't. Mark Zuckerberg: Why? Erica Albright: Because it is exhausting! Dating you is like dating a StairMaster! Mark Zuckerberg: All I meant is that you're not likely to... currently. I wasn't making a comment on your appearance, I was saying that you go to BU. I was stating a fact, that's all. And if it seemed rude, than of course I apologize. Erica Albright: I have to go study. Mark Zuckerberg: You don't have to study. Erica Albright: [Exasperated and angry] Why do you keep saying I don't have to study? Mark Zuckerberg: Because you go to BU! Erica Albright: [Erica stares at him, furious] Mark Zuckerberg: Do you want to get some food? Oh, and the deposition scene between the Winklevoss' attorney and Mark: Gage: Mr. Zuckerberg, do I have your full attention? Mark Zuckerberg: [stares out the window] No. Gage: Do you think I deserve it? Mark Zuckerberg: [looks at Gage] What? Gage: Do you think I deserve your full attention? Mark Zuckerberg: I had to swear an oath before we began this deposition, and I don't want to perjure myself, so I have a legal obligation to say no. Gage: Okay - no. You don't think I deserve your attention. Mark Zuckerberg: I think if your clients want to sit on my shoulders and call themselves tall, they have the right to give it a try - but there's no requirement that I enjoy sitting here listening to people lie. You have part of my attention - you have the minimum amount. The rest of my attention is back at the offices of Facebook, where my colleagues and I are doing things that no one in this room, including and especially your clients, are intellectually or creatively capable of doing. [pauses] Mark Zuckerberg: Did I adequately answer your condescending question? I was enthralled by that scene when I first saw the movie. It was one of the most memorable for me for sure. The way Mark's character just cut the Winklevii, et al. down to size as though the idea of being sued for hundreds of millions of dollars was as much of a nuisance similar to the feeling you have when a pebble gets stuck in your shoe. I just loved it.
