I put together some material for a recent workshop / training day for HSBC. My colleague Brian is a big fan of '12 Angry Men' and how you can use it to analyse team behaviour. How does Henry Fonda's character influence the others, changing his techniques appropriately? It is linked in with a leadership model called "The Managerial Grid" - but that isn't key to this post.
What strikes me is that you can work this idea the other way around. When you are putting together a group of characters, an ensemble piece of work, you could use any group dynamic theory or idea to underpin it.
It doesn't almost matter too much what you use - all the theories look at people at the extremes of behaviour. This helps explain and use the model / theory. But it helps us as extremes are more explosive with regards to drama.
