Source Code hits theaters this Friday, April 1st and you can check out our spoiler-free interviews with the cast by clicking here. There’s one special cameo, though, that ComingSoon.net had the chance to chat with director Duncan Jones about and we wanted to keep his comments separate for those that don’t want the surprise ruined.
The below video does not spoil any plot details (and the cameo can be missed even if you’ve seen the film), but does reveal a loving homage from Jones to another work of science fiction. If you’d like to find out what it is, watch the video in the player below!
