Only because it's slim pickins' on the Hollywood newsfront today do we bring you this semi-precious gem of a casting update. Sam Rockwell, whose Choke was one of the few successful sales at Sundance Snoozefest 08, will star in Moon, a sci-fi flick about a guy stranded on the moon for three years. Though Rockwell only offered up deets on the film after repeated inquiries about his Hanksian beard, he did manage to let loose this promising detail. The director is one Duncan Jones, whose aliases include "former ad exec," "Zowie Bowie," and "David Bowie's son." Jones's first and last directorial effort? A 28-minute short movie called Whistle in 2002. Hope that grizzly bear look is worth it, Sam! [MTV Movies Blog]
