Comic Book Resources has an interview with Celina Jade, the actress portraying Shado on the CW’s Arrow series. I found this bit where she compares the US film industry to China’s action film industry interesting:
It’s been an incredible learning experience because there’s huge differences between working here and there. We joke in Asia that if you’ve done Asian films in China, coming to America is a walk in the park. We don’t have unions, and the safety stuff is very much, “Take the risk and hope for the best!” But here, you have an incredible team around you to protect you and make sure you get the best out of you. It’s different, but I’m enjoying it a lot.
Those pesky unions, trying to protect actors!
