Bruce Lee was, far beywond his movies, an innovator, a pioneer and in many ways a visionary.
His "style" of Jeet kune do was the very first real style of MMA, though the practioners of kajukenbo will probably debate that :)
His best movie was Return of the Dragon, he directed it, wrote is, and choregraphed it and it stand as one of the best displays of MA ever on the screen.
Today, only Donnie Yen comes close in terms of screen MA charisma.
Bruc was to me, like so many others, an inpsiration to start and stay in MA and even the stuff that one learns over the years that casts a bit of a shadow on him and his acomplishments, still one must give credit where credit is do.
I had the chance to train with Dan Inosanto and you can still see the traces of Bruce's MA philosophy on everything that Dan does.
