Source Code was written by Ben Ripley (Species III!), with a once-over by Billy Ray -- a master of the thoughtful genre film. In it, a character is forced relive a train bombing from the point of view of a stranger until he can figure out who's responsible. Jake Gyllenhaal is in negotiations to play the soldier protagonist, or perhaps the third party he inhabits. It's not clear if this is a "conventional" time-travel story or something more akin to Groundhog Day.
Jones is also attached to another sci-fi project called Mute, which he is writing and which he discusses briefly here. Source Code is supposed to start filming early next year, which will probably put the other film (not to mention Escape from the Deep) on the back burner. Meanwhile, awards speculation is starting to simmer around Moon, and especially the richly deserving Sam Rockwell. I'll believe that when I see it -- but Jones' debut showed such remarkable promise that I'm awaiting his next film with bated breath.
