Source Code is Duncan Jones’ follow up film to Moon. This time Jones is exploring that well worn SF trope: time travel. Jake Gyllenhaal’s character, Colter Stevens, is repeatedly sent back in time to try and stop a terrorist bombing of a passenger train. Echoes of Groundhog Dog here but I’m sure Jones will do something different with it. Not Primer different though, this one looks to have more action, though that could be an effect of the trailer.
