Undisputed 2: Last Man Standing is a strange sequel, but the oddness seems completely unintentional. The fight scenes are definitely illicit, though they take place inside a proper boxing ring—a contrast to the “Cage of Death” featured in the first film. George Chambers finds himself back in prison, this time convicted of a crime he claims he didn't commit (unlike the rape accusation from the original movie). After intervening on behalf of his cellmate, Chambers states that "I don't like to see people being bullied," and while he adds a caveat about not liking it when *he’s* doing the bullying, it represents a significant shift in personality. People can certainly change, but it’s unusual to see someone transform from Ving Rhames into Michael Jai White. Chambers is sent to Russia to film a vodka commercial—it's disappointing this Isaac Florentine-directed movie wasn't about a struggling boxer like Apollo Creed. There, he’s arrested for cocaine possession (the drugs were apparently planted in his hotel room) and quickly sentenced to Chornya Cholmi maximum security prison. Chornya Cholmi is translated as Black Hills, although the hills themselves would probably be white with snow; it seems like just a name, similar to “Monster Island” (which is really a peninsula). Like the prison depicted in Black Widow, this Russian facility has everyone—wardens, guards, and prisoners—speaking fluent English (continuing the unintentional irony; Chambers is one of the few characters who speaks any Russian during his commercial shoot). This includes Yuri Boyka (Scott Adkins), the undisputed prison champion. Far removed from the boxing in Undisputed, the focus here is on mixed martial arts that’s choreographed like a wrestling match (complete with referee bumps, which seems to be the only reason these secret, anything-goes fights would have an official). In this regard, Adkins's incredible moves are the highlight of the movie, even if they don’t quite fit the situation—a darker Fight Club style might have been more appropriate. Chambers begins as a boxer, so his initial fight with Boyka is restricted to punches only. The film accurately portrays how Chambers easily dominates Boyka in this scenario; however, both White and Adkins are skilled martial artists, making their first encounter rather lackluster—until Boyka stops holding back and starts using kicks and knees against Chambers, who has also been drugged by his trainer. Overall, casting White feels like a mistake. Rhames couldn’t perform half the moves White can, but he didn't need to; his version of Chambers was both an unstoppable force and an unyielding obstacle. White, through no fault of his own, is forced to portray someone who knows nothing about martial arts and then pretend that Chambers quickly masters everything White knows about MMA.
