Heroes star Masi Oka will star in the casino thriller, 21 for Columbia Pictures and Kevin Spacey's Trigger Street Productions.
The Hollywood Reporter says the film is inspired by the true story of a group of men who learned the art of card counting and won millions of dollars gambling; it's based on Ben Mezrich's best-seller Bringing Down the House: The Inside Story of Six M.I.T. Students Who Took Vegas for Millions. Oka will join Jim Sturgess in a supporting role.
21 is set to begin shooting next month in Boston and Las Vegas; Robert Luketic is directing.
