To make films, it always begins with two words: what and how. First of all, you have to find a story, or what are you going to tell? And you have to find a way to tell it visually.

This is what the difference is between Hong Kong and Chinese cinema - Chinese cinema was made for their own communities. It was for propaganda. But Hong Kong made films to entertain, and they know how to communicate with international audiences.
