Garr Reynolds, better known as PresentationZen is, alongside Nancy Duarte, one of the authorities on presenting and presentations. He posted recently on using storyboards to help craft your story and refine your message. He includes some excellent clips from Pixar’s Bug’s Life and Toy Story storyboard process.
A good storyboard artist is a good storyteller. The drawings do not have to be pretty, but they must have the meaning and the feelings behind the idea – Garr Reynolds
One of the examples of the storyboarding process Garr includes shows the late Joe Ranft in the storyboard and pitching process for A Bugs Life.
