If you love movies (either as a viewer or a creator), you'll want to watch this short video of clips of Brad Bird describing the animation process and how it can effectively tell a story without venturing into absurdity (just because it can).
This video combines excerpts from the three audio commentary tracks on home releases of 'The Iron Giant', 'The Incredibles' and 'Ratatouille', as well as fragments from the behind-the-scenes documentaries. Watching the films prior to watching this video is recommended, but not entirely necessary.
