Why would he leave the program he worked so diligently on to start a new one and make more movies? Isn't it possible he would have continued to refine JKD and do his movies?
I doubt Bruce Lee would be as legendary if he didn't die so young. He'd probably be about as high profile as Chuck Norris. Probably have created a slightly different political landscape within JKD.
I gotta agree, much of his fame is based on his dieing young. Just like James Dean, Jimi Hendrix, and on and on. He would be one of our top American marital artists alongside Chuck Norris, Bill Wallace, and those guys. JKD would have progressed, they would have added a ground component, maybe based on judo due to his friendship with Gene Lebelle.
