The Shrek movies tickled our fancies for a lot of reasons, but one reason was the many callbacks to other famous films. The Dreamsworks production referenced all the top Disney films, and slipped in scenes that reminded us of classic non-animated films, too. Possibly more of them than you realized.
In this video, Bora Barroso collected as many of these references as he could and show them to us side-by-side. There's a list of them at the vimeo page. -via TVOM
