took him 4 years to master muay boran for ong bak then started learning muay korat(i think? muay thai style of bone breaking) for the protector. the dude is mainly a stuntman and fucken good at it too pulling all that shit without wires.
That would actually be pretty cool, but i think Jackie isnt as physically able now (age) and has to use wires in all his movies, those two guys in their primes with no wires would have been a hell of a movie.
I remember reading somewhere that he learned his style just for his first movie. And it was supposed to be some ancient deadly style that gave birth to Muay Thai, but I don't really remember it all. I don't remember reading about him competing.
