I go to Shenzhen, China, and am taken to a vast luxury spa with a hundred leather recliners and a hundred accompanying plasma screen televisions bolted to the ceiling.

Such huge money has been made in China - it can be hundreds of millions in a year - and there's a need to validate it by showing what they can buy and how much of it.

I think, at least for me, I'm so impressed by Shanghai and how all of China continues to evolve. On a style level, you're seeing this increased sophistication and brand awareness.

In order for me to write a scene, it's very important for me to see and experience everything with my own eyes, so yes, I was able to visit some remarkable houses and destinations while I was in China.

I met a Shanghai photographer who finds these old streets and matches the French names to what they are today. I was able to find my grandfather's block, and just walking the same streets and finding his house was deeply moving. I finally felt connected to China.

The most important thing to keep in mind is the incredible diversity of talent that's out there - there are so many great actors from all over Asia, from Singapore and Hong Kong to the Philippines and Mainland China, not to mention many great Asian-American actors who are eager for fun and challenging roles.
