This is a link to a video showing how the actors were filmed to make Avatar. What really blew me away about this film is the performances of the actors and how they were captured by the new technology. The expressions, even the little tiny nuances, were absolutely wonderful.
This is what will totally revolutionize film making as we know it. It’s not the 3D, it’s not the trees and floating mountains, it’s all about the performances of these actors and how it was transferred through the technology to the screen.
See this movie again, and watch every single CGI performance captured frame with Zoe Saldana. Wonderful!
