When I came to Hollywood, I spoke no English - except nobody bullied me. Every day, I had nothing to do except training in English, to keep talking.

Money for me today does not really matter.

I just couldn't stop thinking about what landmines are doing to people here. I told people - my friends - about it, but it was just not enough. I knew I had to do more.

First, there are many who can fight, but they're small in stature; Zhang Lanxin is 177 cm [5'9"+] tall, with very long hands and legs, and very quick. In the scenes, I tried to show all of her special strengths and qualities. Plus, Zhang Lanxin has extraordinary staying power: it was only yesterday at the airport that I saw her cell phone photos from the hospital where she was having blood clots in her knee being cleared up, and I hadn't known till then that she had this problem.

Sometimes I do need to go to karaoke, sometimes I need to relax.

The life of an action star is very short. I want to be an actor like Robert De Niro , like Dustin Hoffman or Clint Eastwood who in their 70s or 80s can still act.

In my view, Zhang Lanxin is one of our best female martial artists, and I can't rate her highly enough.
