Variety reports that he will play Sean Parker, the founder of Napster.

Finally, the role of Eduardo Saverin, a cofounder of Facebook, has gone to Garfield. Hes previously appeared in two episodes of Doctor Who, and plays a part in The Imaginarium of Doctor Parnassus, as well.So it appears that Michael Cera and Shia LaBeouf, who were at times said to be the two actors most likely to play Mark Zuckerberg, either didnt want or didnt get the role. But if Facebook fans are worried about a lack of recognizable faces attached to this movie, it may comfort them to know that Aaron Sorkin, David Fincher, and Kevin Spacey are still onboard as writer, director, and executive producer, respectively.
