Finally watched the trailer, and one question is nagging my mind;
"Was Bruce Lee this arrogant and fond of violence?"
I think I saw something about him being part of a gang in China and violent before being trained by Yip Man, but the events of this movie take place after he moved to the United States.
He was involved in many street fights AFTER being trained by Yip Man, too. He got into rooftop fights against students of other styles, and reportedly, was sent to the US as he way to keep him from further trouble. Even to do that, they had to get favors to even let him off the country as he was in a list of known troublemakers and was unlikely to be given clear exit.
He is said to have fought several challenge matches and a lot of his original evangelizing about HIS kung fu was how it was so much superior to karate.
He was VERY arrogant, though also thoughtful and kind to his friends.
One of his early girlfriends in the US apparently broke up with him because she could not stand him exclusively going on about his plans and his future and his kung-fu philosophies and himself, in short.
Most biographies kinda agree on this.
However, it is doubtful anyone without a lot of such self-assurance and ambition could have achieved all he did or demanded so much of himself.
I know a lot of martial arts champions and it is hard to be top dog at any hard competitive sport without a lot of self-confidence and pride in what you do. The ideal of the humble, self-effacing martial arts master would not have become a superstar and changed the perception of the martial arts across the world.
You read for example, sword master Miyamoto Musashi's GO RI NO SHO, or Book of Five Rings, and there is plenty of stating how much better his style is than anyone else's.
Comes with the territory.
This film is not worth my time.
