Seconded.
Pretty much every biographical doc on Bruce Lee longer than 500 words would state that Bruce Lee revered Ali. He'd never say in public that he'd leave him a cripple in a fight. The guy used to watch tapes of Ali in the mirror so he could see him fight Southpaw.
Its really interesting that for a guy as research happy as Q.T. the scene with Bruce Lee involves him stating something so opposite to his beliefs.
Yes, Bruce Lee was cocky but not to THAT extent. Tarantino misrepresented Bruce Lee so the audience would be on Brad Pitt's side.
No wonder his daughter is upset.
