I think the book struck me in a few ways that I thought very interesting to pick it as my first martial arts film. It has a very strong female character and it was very abundant in classic Chinese textures.
But really, for the most part - doing a prequel is great because you do have room to kind of free this character and how they got to where they are instead of being a slave to exactly what the previous actor did.
Making a film of a work you've played for six weeks gives you intimate knowledge of the character. By the time you go in front of the camera you've worked out the behavior and life of a character.
I didn't realize House would be the central character, more the bitter comic relief appearing occasionally. I relish his wounded nature - the lameness, the scarred Byronic hero.
Wong Kar Wai is a very intense character, very personable, and I believe in general he does not like and he would not want his actors to show their true looks and their true personality on screen.
