Continuity mistake: When Eduardo finds the letter on the mantlepiece about them apparently stealing the idea for Facebook and asks Mark if they did or not, he places a bottle on the mantlepiece just before he finds the letter. This bottle rotates slightly between shots without him touching it after placing it down. (00:49:15)THGhost
Factual error: When Mark types email addresses in to tell people about facemash, he writes to several people @harvard.edu. At the time the movie takes place, undergraduate email addresses were all of the form email@example.com. Furthermore, the network brought down by facemash would have been referred to as the FAS network. (FAS stands for Faculty of Arts and Sciences; the eponymous network covered all buildings within the College and Graduate School of Arts and Sciences.).
Tyler Winklevoss: I'm six-five,220 pounds, and there are two of me.
Cameron Winklevoss: What, do you wanna hire an IP lawyer and sue him?
Divya Narendra: No, I wanna hire the Sopranos to beat the shit out of him with a hammer!
Question: When Eduardo discovers the dilution of his percentage, he asks Mark if he did it because of the "article about the chicken", which accused Eduardo of forced animal cannibalism. Sean Parker hears this and says, "What's he talking about?" and then says "Seriously, what's the chicken?" Is this implying he was the one who gave the chicken story to Mark's lawyer so he could use it in the previous scene where he mentions it?
