Greg Grunberg

After four seasons as a regular on the sci-fi series Alias, Greg Grunberg returned to the primetime TV scene with his role as Matt Parkman on the NBC series Heroes in 2006.

He has also appeared on hit shows Felicity, NYPD Blue and Melrose Place. The actor has a long-standing working relationship with film/TV director J.J. Abrams and has collaborated with the director on many projects — most notably Mission: Impossible III.
