The idea behind the forthcoming Jake Gyllenhaal undertaking Source Code sounds pretty ridiculous - the government has developed a way to insert the consciousness of one of their soldiers into another person, for the last 8 minutes of their life. If this were described to me with no other explanation, I'd say it would make for a fairly average, but likely forgettable, sci-fi movie. The trailer isn't half bad but still leaves a little to be desired. However, it is directed by Duncan Jones - who won me over 150% with Moon. So, I'm reserving judgment until I actually see the thing as I bet he handles it better than your average director.
