The Hero's Journey pattern is followed in many famous movies today (Star Wars and Finding Nemo!)
We used an online tool for planning in pairs at http://www.readwritethink.org/files/resources/interactives/herosjourney/heros_journey.html
There was so much discussion about ideas as the planning went on. We found ancient names on-line and we used plots we knew to help us and spark ideas.
