My mum lives in Boston; she's famous for teaching wushu and t'ai chi. So from when I was young, my mum and aunt were like: 'You're training; you're not playing baseball or football.' Training every day was normal. Later, when I was almost a teenager, Bruce Lee became my idol.

Doing a movie is a stressful thing. You spend months of you life focusing into that one project, and I want to make sure I do something I really like or I'm really passionate about.

I guess I'm pretty lucky because in childhood I studied so many martial arts styles and I never stopped researching them, my body is very adjustable and I can turn into different expressions with my body.

I think every actor wants to try out different things.

My action follows my characters. If a character is a cop, you cannot be posing all the time, you cannot fly off the roof because it doesn't make any sense - it's not practical.

For me, the challenge of a period film is that, unlike a contemporary film where the character can be very free-form when it comes to the acting, there's a burden to acting in a period film because you have to stay within the character's historical background and the gestures of certain periods.

I spent a couple of years doing American films. I did a few.
