Dude! Tony Jaa is so...epic! And in his movies: He doesn't use any wires,any stunt doubles,nothing like that! All the flips,running on people's shoulders (Yeah you heard me right) it's all done by him :) Funny thing too...I had a dream last night where I was in that chase scene and I wasn't even thinking about the movie,or watching it O.O Wierd how dreams work  huh?
