Emma Coats an artist at Pixar was tweeting some story basics and there’s a nice round up of them here: http://www.pixartouchbook.com/blog/2011/5/15/pixar-story-rules-one-version.html
Including some great advice and creative exercises such as:
#20: Exercise: take the building blocks of a movie you dislike. How d’you rearrange them into what you DO like?
#13: Give your characters opinions. Passive/malleable might seem likable to you as you write, but it’s poison to the audience.
Thoroughly recommend reading through these 22 tweets size bits of gold.
