21 centers on "Six MIT students, in a blackjack team, [who] train to become experts in card counting and subsequently take Vegas casinos for millions in winnings. However, casino workers become suspicious and attempt to take down the team, using any means necessary." Sturgess plays Ben Campell, a numbers genius who is struggling to pay his bills. He is recruited into a team of card counters by his professor (as played by Spacey) and as to be expected, the good times don't last long. Ben starts to lose control and his mentor and friends turn on him just as the casinos are starting to catch on to the scam.
To be honest, as much as I enjoyed the book, I don't think I will be first in line for this one. Part of what made the book so interesting to me was that these were just regular people who became 'criminals'. The film seems to want to take a more Ocean's 11 approach right down to the music in the trailer, and, frankly, it's been done before. 21 hits theaters on March 28th.
