Unfortunately this review will be a bit incomplete as the version I saw didn't have subtitles and I don't speak Thai. That said, I have not seen the first movie, but when I heard Tony Jaa had a cameo I looked it up. The lead of the movie is played by Petchtai Wongkamlao who was George in Ong Bak. This is an action movie and there are fight scenes, but it's clear that Petchtai Wongkamlao's boxing ability is still in it's earlier stages. The plot as far as I can tell is about an agent trying to stop a threat to the nation, posing as a high profile singer in the mean time. The first action sequence is probably the best which is a nice gun battle in a gay club followed by some car action. The rest of the action scenes in the movie (with the exception of the one featuring Tony Jaa) seem to be more or less about introducing a skilled fighter and then killing him off in some silly way. Basically you never get to see any real martial arts displayed throughout. Tony Jaa's appearance seems to be about his character looking for an elephant figurine (an obvious reference to the Protector). The fight itself only lasts about a minute and takes place outside at a vendor stand, but it was still a treat to see Tony Jaa in action if just for a minute. The comedy seemed pretty good, a lot of it was visual with references to Ong Bak and probably other Thai movies as well. Hopefully someone will add a review who has seen the subtitled version, but I did want to give some heads up since there are no other reviews. Overall, probably not worth going out of your way to find, but if you come across it check it out.
