Greg Grunberg

Something many fans of Greg Grunberg may have noticed is that the actor has appeared in a noticeably large number of projects by producer J.J. Abrams. This is because Grunberg and Abrams, in fact, grew up together and remained friends. His first big break came when his friend set to work on a one-hour dramedy called Felicity. Grunberg was cast in the role of Sean Blumberg -- a role he would continue to play for all of the show's four-year run. His next notable part came when he assumed the recurring role of Agent EricWeiss on the spy show Alias. He then popped up in the Abrams pilot for the series Lost, as the pilot of the crashed airplane, before joining the cast of the wildly popular sci-fi series Heroes as police officer Matt Parkman, whose superhuman power is that he is able to hear other people's thoughts.
