I know it is a mainstream movie and everyone has seen it. But try watching Disney's Snow White again, and remember that it was released in 1937. Your statement "defined the animated films" is more applicable to that movie than anything else.
The first chapters deal with the creation of the Snow White film, and the startup culture within the Disney studios at that time.
Co-incidentally, both authors are referenced in the film The Incredibles (the original subject of the OP's post)
I can't help but wonder if this is a shout-out/jab to the perennial Stan Lee cameo in films based off Marvel characters, especially considering that The Incredibles was often seen as competing with, and compared favorably against, Fantastic Four (2005).
