I can just remember It´s an asian action movie.

A guy is sleeping outside a fighting school in a tent and the master of the school tests the guys fighting ability. The "guy" using nunchakus(spelling?).
The master dies later on by "the main bad guy" inside the school.
I think it is a scene where the "guy" is fighting on a baseball field. And some scenes where he is in high grass.

It isn't much help, but it's all I got.

I watched this movie but I can't remember the name. I remember the last scene where that guy and one his friend fights the bad guy at some big plase. Like a big temple with lots of stone bricks. And they are using like karate but with spells too. Like when he spins nunchakus he makes a ball of water around him and like that. Maybe can someone remember name from this scene. Hope it helps :)
