Duncan Jones follows up his indie success Moon with another clever, tightly contained sci-fi story, although this one's got a lot more action.

Jake Gyllenhaal has just eight minutes to stop a train being destroyed by a terrorist bomb – but if he fails, he can go back in time and relive those eight minutes again and again. You won't give this film eight minutes' thought afterwards, but it's a blast while you're watching it.
