I think all actors want to change. When you do something many times, over and over, you want to do something fresh. But movie is still my business. A lot of action actors want change, but no studio wants to spend money on something that is not guaranteed; not proven. I think it is very difficult. It is hard to change.

In my mind, martial arts movies are martial arts movies and action is action. It's quite different, because martial arts doesn't just have physical form; you have a philosophy, internal and external. A lot of it involves your life. How you see the world. An action film I think is just about the movement. I think it's different.

I've been learning martial arts since I was 8 years old.

Wushu is a move in Chinese, a physical move. An attack. Wushu is like an art.

I think 'Hero' is not a real martial arts movie; it is not about violence, or formula.

I believe the world is one big family, and we need to help each other.

Zhang is a friend of mine: he said forget about acting and just do normal things in the movie.
