Bruce Lee is one of the most famous martial artists in the world, which is saying something since there are tons of great action movie stars both past and present. There was just something about him that was magnetic. His physical abilities were unparalleled. He would have to move slower when shooting movies because his movements were too fast for the camera to pick up. He even created his own martial arts system called Jeet Kun Do, which he developed while he was paralyzed. That's how much of a bad ass he is.
He came back into the spotlight most recently in Quentin Tarantino's Once Upon a Time in Hollywood where he was depicted by actor Mike Moh. Some called the performance unfair to Lee's legacy because he is shown as a braggart who gets bested by Brad Pitt.
