If Tony Jaa does films in the U.S..
Id prefer he stay in Thailand and do things his own way. But if he went to the U.S Id like to see him work with the RIGHT people not a bunch of executives who dont understand him or the history/philosphy etc of martial arts.
A few ideas :
The RZA directing and doing the score
Jackie Earle Haley : knows Karate and would be a good villian (maybe a sex trafficker of Thai women). His moves in Watchmen were impressive. hes 5ft5 to Jaas 5ft6 so they would be evnly matched
Jackie Chan directing : unlikely though. hes a good director but these days only seems to be chasing the money not the art with junk like the Kung-fu kid
your ideas?
