But according to Narendra and the frères Winklevoss, Zuckerberg stole their ideas and code and later used them to build Facebook. The three ultimately slapped Zuckerberg and Facebook with a 2007 lawsuit. (The two parties' long-running, oft-renewed spat has since disappeared -- probably for good -- in a quiet settlement.)

Since the events depicted in Mezrich's book, the Winklevoss brothers went on to collect their share of the rumored $65 million settlement with Facebook (minus some nagging legal fees) and compete in the 2008 Beijing Olympics -- so they've got that going for them. Narendra, meanwhile, is staying busy.

Now, back to Sorkin's script. The scene in question takes place as Narendra, Winklevoss and Winklevoss and ask Harvard president Lawrence Summers to help them stop Zuckerberg and Facebook, claiming that he stole intellectual property that could be worth millions. Millions?

SUMMERS: You might be letting your imagination run away with you.

TYLER: With all due respect, I don't think you're in any position to make that call.

SUMMERS: I was U.S. Treasury Secretary, I'm in some position to make that call.

Snap! So, did it happen anything like that? Who knows. Should Summers have intervened? Is a Facebook valuation in the millions really so ridiculous now?

Expect these and other Big Questions to be answered -- no doubt through scene upon scene of arch, overly articulate hallway patter -- when The Social Network hits theaters sometime in 2011.
