No spoilers here but let me just say that the trailer doesn't give the film any curious benefits. Timberlake can act, that goes without saying now, but he is let down a little by the story. In a nutshell, there's no money in this futuristic world, there's time. There are also zones as named in the film that start from the ghettos to the ultra high class. Once someone is 25 they need to work to earn time to stay alive but the higher the zone the longer the life. J.T plays Will, who after an unfortunate family circumstance and a meeting of a stranger ends up with lot's of time. Moving up zones he meets a beautiful daughter (The china doll-like Amanda Seyfried) of a rich banker type with infinity time in his possession. The pair get together and go on the run in an inspired Robin Hood type escapade. Andrew Niccol also directed the superior 'Gattaca' and this does have a few unique ideas, just not enough explanations either. Cillian Murphy rocks though.
