In the course of these 2 movies it seems like jaa has really risen to the ranks of other martial arts superstars like jackie & jet li, but I think his cheoreography really has alot of subtle homages to them as well as people like Bruce Lee. I think another interesting thing about jaas cheoreography is that he can actually perform alot of the fights from ong bak as live performances, sometimes you have to wonder if they are actually hitting eachother.
