Jesse Eisenberg is an Oscar-nominated American actor most famous for inventing Facebook (citation needed) and being mistaken for Michael Cera.
Starting with Roger Dodger, Jesse appears to have made a career from playing nerdy, girlfriend-challenged types. He tries to play off a Roger Waters song as his own in The Squid and the Whale (getting slightly typecast in the plagiarism stakes...?!), survives Kristen Stewart's lip-chewing - I mean - scenery chewing acting in Adventureland, hunts Twinkies with Woody Harrelson in Zombieland, and finally invents a way to aid procrastinators/stalkers everywhere in The Social Network. Has about five films coming up in the next couple of years, and hopefully none of these will feature him in flip-flops and shorts while it's snowing out (I blame you, Zuckerberg). More soundtracks from Trent Reznor would be most welcome though.
