Actor Jesse Eisenberg who will be playing Mark Zuckerberg in the upcoming film "The Social Network". Jesse has a striking resemblance to Mark and also has the nerdy look about him which Zuckerberg has. This was definitely an excellent casting choice.
You may recognize Eisenberg from previous films such as Zombieland, Cursed, and The Village. He has never had any major roles before, this will be his first leading role. I think this film will definitely put Eisenberg on the map in Hollywood. From the movie trailer it seems Jesse portrays Mark Zuckerberg very well.
