Jacob Pitts (Across the Universe) and Liza Lapira (Domino) have been added to the cast of Columbia's 21, according to Variety.

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.

Robert Luketic directs, with Kevin Spacey, Laurence Fishburne and Masi Oka starring.

Pitts recently completed Quid Pro Quo. Lapira's credits include Huff and Grey's Anatomy.
