This SFX reel by animatronics artist Gustav Hoegen is so crazy good you might have thought his work was CGI. His credits include Prometheus, Clash of the Titans, Doctor Who, Charlie and the Chocolate Factory, and The Hitchhiker's Guide to the Galaxy. There are some potential spoilers so if you haven't seen the aforementioned movies beware. Thanks to IO9 & Geekologie for the video.
Seeing the inner workings of these creations really makes me jealous of Hoegen's engineering skills. I'm so glad animatronics is alive and kicking and not some lost art medium.
