Ali Larter ("Heroes") co-stars as Martin's fellow operative Crystal Quest, while Rob Mayes ("John Dies at the End"), Tina Majorino ("Napoleon Dynamite"), Steve Harris ("Awake"), Amber Valletta ("Revenge") and Lux Haney Jardine ("Abraham Lincon: Vampire Hunter") make up the rest of the cast.
The series is based on the 2005 novel of the same name by Robert Littell, with "Sleeper Cell" creators Ethan Reiff and Cyrus Voris set to serve as showrunners and EPs. David Semel ("Person of Interest") directed the pilot, which was written by Jeffrey Nachmanoff ("Traitor"). "Live Free or Die Hard" writer Mark Bomback developed the story with Gordon and Nachmanoff.
Bean played a major (but, well, not ongoing) role in "Game of Thrones," and more recently played a CIA agent alongside Ashley Judd in "Missing." Check out a trailer for "Legends" below:
