I asked each if [Yao Xingtong and Zhang Lanxin] was afraid of heights. Each said no, and although they had never had the action movie experience they were willing to be trained. Then I asked if they could swim, and each said yes, but she (gestures toward YX) is better. She said, I can also dive, in fact I once won a diving championship in an international competition. Then she said, "But big brother, I'm not very strong," and I said that's all right.

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.

You don't need a reason to be nice to someone.

My wish is to bring my heroes to the big screen, and many of them have already appeared in my films.

I've seen too many ups and downs in the movie industry.

I thought I should forget Hollywood and go back to Hong Kong. I'm so lucky that finally Hollywood accepts my comedy fighting.

China produces 600 movies in a year, of which 3 or 4 go abroad, while of the several hundred they make, we only bring in 50. It's 50 now, but that could be expanded later on.
