After the success of "Ong-Bak", Mum was able to write, direct and star in his own film, "The Bodyguard", a wire fu action comedy in which he portrays a bodyguard who is fired after the billionaire he is protecting is killed. Martial-arts action was choreographed by Panna Ritikrai, and "Ong-Bak's" Tony Jaa has a small part as a fighter in a supermarket. One of the most famous scenes is when Mum's character runs naked across Bangkok's crowded Victory Monument public square, a major junction for public transportation. In the "making of" documentary on the film's DVD, Mum said the scene was one of the most embarrassing things he has ever done.
