I saw Pixar’s latest animated film, Monsters, Inc., a few weeks ago, and was somewhat disappointed that there were no “outtakes” during the closing credits. Today Pixar has re-released the film, including outtakes. You can sample the outtakes at the Monsters, Inc website.
The Pixar Theater hosts the original outtakes from A Bug’s Life and Toy Story 2.
In related news, if you have Apple’s Quicktime software (free for MacOS and Windows), Apple’s movie trailers page is just awesome.
