The co-creator and showrunner on NBC’s new high-concept drama has left the show. Sources tell Deadline that Mark Friedman (The Forgotten, Home Of The Brave) made the decision to exit Believe, from Warner Bros Television and Bad Robot Productions, on his own accord and that the parting was agreeable. Believe’s other co-creator Alfonso Cuaron (Gravity, Children Of Men), who directed and co-wrote the pilot, will remain as executive producer alongside J.J. Abrams. The Friedman move recalls a similar situation 18 months ago in which the co-creator/executive producer/showrunner of another Bad Robot midseason drama, Alcatraz, exited ahead of that series’ launch. Elizabeth Sarnoff, who had quietly been elevated to EP two months earlier, left that Fox drama — citing the usual “creative differences”. Abrams later said of Sarnoff, “She didn’t feel like she was the right person to run the show.”
