Zhang is a friend of mine: he said forget about acting and just do normal things in the movie.
Jet LiI wish heroes didn't exist. Whenever we need a hero, it's because there's a problem that needs to be solved; it's because two groups of people, or two countries, are hurting one another, so a hero is needed to save us. If everyone were at peace, if everyone were happy, why would we need heroes? The world is better off without heroes.
