Martial arts legend Tony Jaa writes, directs, produces and stars in 'Ong Bak 3,' the third and final installment in one of the most beloved action series of all time. Picking up at the cliffhanger ending where 'Ong Bak 2' leaves off, Jaa ramps up the epic supernatural elements of the previous film, while still maintaining the trademark bone-crunching action that the series is known for. This time he must face his ultimate enemy: a fierce supernatural warrior named "Demon Crow," played by fellow martial arts sensation Dan Chupong ('Dynamite Warrior'). Eagerly anticipated by martial arts aficionados for some time, the matchup of Jaa and Chupong is explosive.
