Moon director Duncan Jones certainly had a bit more cash to pay for with his follow-up, Source Code, and now the first trailer for the movie has arrived. The neat sci-fi premise sees Jake Gyllenhaal waking up on train, not knowing how he got, and then a few minutes later getting blown up in a bombing. However he’s actually a soldier who’s part of a programme that can send people back into the last eight minutes of someone’s life, and so Jake is sent back again, trying to find out who’s responsible for the explosion, while also falling for a fellow passenger, played by Michelle Monahan, who causes him to want to change events, rather than simply investigate them. While it does look more than a little cool, you can already feel the endless time travel paradoxes creeping in around the edges, and it’ll be intriguing to discover how and if they manage to get round them. The film hits cinemas next spring, and should be well worth a look.
