21 (Blu-ray)

im Sturgess (Across the Universe) plays brilliant, blue-collar scholar Ben Campbell, whose doubts that he'll win a scholarship to Harvard Medical School compel him to join a secret, M.I.T. gang of math whiz kids. Under the silky but chilling command of a math professor (Kevin Spacey), Jim and the others master card counting, i.e., the statistical analysis of cards dealt in blackjack games. The team lives a humdrum existence during the week, but on weekends in Sin City, the students are rolling in cash, going to exclusive clubs, and feeling on top of the world.
