Directed by Louis Letterier, a protégé of filmmaker Luc Besson (who co-wrote and produced this movie), Unleashed uses A-list star power and stylish cinematic technique to bring class to something that might easily have been a routine martial-arts action flick. Jet Li plays Danny, adopted in childhood and trained (via cruel Pavlovian methods) to be a remorseless killing machine by gangster Bob Hoskins, who sics the mature Danny on recalcitrant debtors. When by chance Danny escapes his captor, he is taken in by blind piano tuner Morgan Freeman and his adopted daughter, played by Kerry Condon. We see Danny gradually becoming humanized as his new friends shower him with care and affection, and while this sort of acting doesn’t come easily to Li, the veteran action star holds his own in his scenes with Freeman and Condon. Although Unleashed has more heart than previous Li outings, its highlights are still bone-crunching fight scenes, in this case choreographed by the legendary Yuen Wo Ping (whose other Hollywood successes include the Matrix movies). He’s shown working with Li and various stuntmen in “Serve No Master,” a ten-minute featurette that’s the best of this disc’s many extras.
