21 directed by Robert Luketic (starring Jim Sturgess, Kevin Spacey, Laurence Fishburne, Kate Bosworth)

21 (2008). Screenplay by Peter Steinfeld and Allan Loeb from the book Bringing Down the House by Ben Mezrich.

Ben Campbell (Jim Sturgess) is a brilliant MIT student on his way to Harvard Medical School. He's already been accepted, but the money is an issue. Ben is up for a full scholarship, but so are 76 other people, and he has spent so much time studying, he's had little opportunity for the "life experience" the scholarship board seeks from that one "dazzling" candidate that deserves the $300,000 free ride.

So, when his Nonlinear Equations professor, Mickey Rosa (Kevin Spacey), recruits him to his team of other brilliant students to count cards in Las Vegas casinos, he reluctantly accepts — on the condition that once he's earned the three-hundred grand, he's out.

Spacey is electric as Professor Rosa, but it's Sturgess's work as Ben Campbell that grounds this flight of fancy in reality. He is instantly likable, and his troubles are relatable, even though few people have actually experienced them. Laurence Fishburne also has a nice turn as ultra-intimidating security man Cole Williams, a man who does whatever it takes to keep his job in an increasingly computer-controlled arena.

Though it's supposedly based on a true story, 21 is pure Hollywood all the way. From its underprivileged hero given the opportunity of a lifetime, to its instant inclusion of the hero's dream love interest (here Kate Bosworth), to how Ben drops his geek friends once he gets the chance to hang out with cooler people, to how the student surpasses the teacher.

The first portion of the movie is so predictable, in fact — and so spelled-out for the general audience — that it's a struggle just to get through to the interesting portion: the actual Vegas scenes. As a whole, however, 21 is a lot of fun, and I was surprised at how much I thought about it after it was over, especially that insipid but catchy phrase, "Winner, winner, chicken dinner."
