Actor Jesse Eisenberg and director David Fincher of 'The Social Network' created a movie about Facebook and its founder Mark Zuckerberg that lays out the controversial story behind its inception, and yet ... neither of them actually uses Facebook.

Eisenberg and Fincher sat down for a Q&A at the Apple retail store in the Soho neighborhood of Manhattan on Sept. 23 to answer questions about the movie, and Eisenberg talked about what it was like acting like a tough guy and why he didn't mind taking on such a controversial role.

Near the beginning of the discussion, Fincher asked the crowd how many people use Facebook and, not surprisingly, almost everyone raised their hands. Eisenberg, however, admitted he doesn't use it, and conceded that asking whether someone uses Facebook these days is like asking if they use the telephone.
