So Tarantino was making fun at the whole martial arts genre....
with the Bruce Lee character.
shareNah, he already did that with Kill Bill.
With this film, he was poking fun at the pretence of actors. It reminds me of a 1995 Chinese movie called High Risk. It's a parody of action movies where the two main characters are a movie star and his bodyguard friend. The movie star is a Bruce Lee clone, right down to the Game of Death outfit that Uma Thurman had worn in Kill Bill.
