Tony Jaa's 'Ong Bak 2' just released on DVD in the UK after a run at the cinema last year. It was reasonably well recieved, but now the 'wow' factor about his choreography and contact level has diminished, people are looking for him to step up and make a good film, as opposed to a load of nonsense that links some good action scenes.
Apparently, Ong Bak 2 saw him go overbudget, over schedule, and have a nervous breakdown from the pressure of directing and starring in it.
Ong Bak 3 may, or may not, be a continuation of the prequel, but is due to start filming shortly.
On the original subject, I have no idea why they would call this 'the karate kid', and wish they had updated 'The last Dragon' instead, which was always the better movie.
