Pixar published Storytelling in a Box through Khan Academy. This is free content that looks at the art of storytelling as Pixar does it, through the eyes of many Pixar employees.

There are six sections:
  1. We are all storytellers
  2. Character
  3. Story structure
  4. Visual language
  5. Film grammar
  6. Pitching and feedback

In addition to the general information, there are at least four activities in each section and some sections have six.
