From what I know they are using CGI for Godzilla, but I would love if Andy Serkis did a motion-capture performance. I am wondering if there will be any animatronic models or if it will be 100% CGI?
If you think about it, performance capture is kind of the modern equivalent of guy-in-a-rubber-suit special effects. You're using the movements of a human performer to directly animate a special-effects creature. So it would be appropriate here.
