The first Undisputed, from 2002, was a solid (if unexceptional) prison brawl movie that found home video success thanks to the combined star power of Wesley Snipes and Ving Rhames following a poor theatrical run. Yet even without Snipes, Rhames, or director Walter Hill, Undisputed II: Last Man Standing improved on the first film in almost every way, delivering bone-crunching action scenes, a more tangible dramatic arc, and a pair of leads in Michael Jai White and Scott Adkins whose chemistry in and out of the ring will keep you glued to the screen.
