He did win a Cha-Cha dance competition in Hong Kong but also the Boxing tournament. It's not clear whether he liked dancing or Martial Arts more. I think he liked both and used some of his dancing skills to enhance fight choreography when he got in to movies. But remember that when Bruce Lee arrived in America he didn't come here to be a movie star. He studied philosophy in college and made money teaching his own brand of Kung Fu. He got discovered as an actor after doing demonstrations at Martial Arts seminars. By the time he auditioned for the Green Hornet Bruce Lee was a very serious Martial Artist. That was the focus of his life up to that point then came the movies in China and breaking in to Hollywood before his untimely death.
I don't know what there is to debate. He trained for the tournament and won. He wasn't a professional Boxer but he did compete in competition.the boxing tournament is absolutely debatable. He was decidedly not a trained boxer.
I'm not trying to elevate him to anything. I'm trying to discover more about the real Bruce Lee and this Gary Elms situation is part of the story.Why not just be happy with what he left us instead of trying to elevate and elevate to the point of absurdity? He did some great stuff. Enjoy that! It was more than enough from one guy.
