I first found this on a friend's post to facebook: Pixar's 22 rule of storytelling.
Then I asked if this was bona fide Pixar's? And this is what I have found.
Tubefilter is one of the site with the background to this. Leading on I discover a book on Pixar: The Pixar Touch which I hope to read sometime. A question remain which I shall think about later (no time lah). Which popular old stories predating Pixar had also followed these rules? E.g., Joseph, Esther etc. in the Bible? Stories from the Mahabhrata? Journey to the West?
