Holy shit! Rent this movie. Tony Jaa can do things humans should not be allowed to do. Here's the story: Don, a Bangkok criminal, tries to buy an amulet off a villager. Villager refuses to sell, so Don steals the head of the village's Buddha in retaliation. Villager named Ting (Tony Jaa) volunteers to get it back. He goes to Bangkok, meets up with a criminally oriented cousin who doesn't want to help him. They eventually do work together to retrieve Ong-Bak (the head from the statue) from a big criminal gang that is into drugs as well as boxing and the betting thereon. There's a lot of fighting.
Story is dumb, but you expect that. The fight scenes, awesome. Think of Jean Claude van Damme only 5 times better. And without the fast camera switches. In fact, throughout the movie on cool shots, they replay the action from two or three different angles. I think just to show you they didn't gimmick it. And you get to see the piece again without hitting replay.
Now that Jackie Chan no longer does the cool stunts and has much lamer fight scenes, Tony Jaa will be the one I go to see.
