There's a lot of thinking when you choreograph something. You're not just choreographing some bodies, arms, legs flying around to look cool. It's a lot more complicated and sophisticated. You also have to deal with the connection of the whole film, so when I choreograph, I think of the movement itself, the camera angles, the characters.
Many friends of mine told me that normally only guys like a kung fu movie and the girls would be turned off - they want to see a love story. But Ip Man is a family man, so the women see this and go: 'I want my husband to be like this man. He'll be a scholar, he'll be fighting, he'll care for the family.' So we had a bigger audience.
