Here's a quick clip of Brad Bird talking about the film creation process and giving up particular ideas for the good of the overall concept. I find that's one thing people learn along the way: it's good to critique and trash ideas, just as long as it doesn't get personal.His dig on "businessmen" is overgeneralization of course, and we understand his point. The film is a design process, and can't be reduced to analysis.The clip is from an interview on The Incredibles DVD. The making-of portions are wonderful and illustrate what a passionate filmmaker Bird is.
