I want to thank my mum, my daddy, my coach, my teacher, everybody in my life.

Tibetan Buddhism, has inspired me and accelerated my understanding of life.

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 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.

You can use martial arts to tell a different story. Ang Lee used martial arts in 'Crouching Tiger, Hidden Dragon' to talk about love.

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

You need to drop down. Nobody is perfect, nobody is superhero.
