Bruce Lee was more than just an actor and anyone who says so is probably a hater or isn’t a martial artist. Bruce Lee was the first famous martial artist at least that I know that basically called bullshyt on all the mystical Asian martial arts that Americans were enamored with. He ended up making his own form Jeet Kune Do where he emphasized moves that were effective in actual combat and practicing them against resisting opponent. He wasn’t with that fake shyt where you’re practicing a 5 hit combo against a dude standing there or even aiding you in the movements.
It turned Jeet Kune Do into basically the amalgam of Boxing, Wing Chun, Kung Fu, Wrestling etc. Homie laid the groundwork in what we now see is MMA...everything being thrown into the ring with only what’s practical surviving. None of that drunken monkey stance, praying mantis stance, and bullshyt that’ll get your ass whooped in a fight.
