I'm not a master of films. I'm rather a slave.

When I sent those scripts, that was the lowest point of my life. We'd just had our second son, and when I went to collect them from hospital, I went to the bank to try and get some money to buy some diapers, the screen showed I've got $26 left.

I think that at heart I am an old-fashioned Chinese, really I am.

So it [3D] is something I'm still learning, it's fresh, so if the budget allows I'll do it again and just see how far it goes because it's the frontier, it's more interesting. It's still expensive, the projection system can be annoying sometimes, it's not really regulated or perfected yet, so it's still expensive. If I do a lower budget I'll just do 2D, but if the budget allows I think I'll try 3D.

Sexuality is a big issue, but there are others - how much you commit to a relationship, to social obligation, to honesty and being honest with yourself.

With 3D you're right there immersed in the world.

Fighting for identity is something that is very much in my life.
