I'm just going to share this tip for developing characters that I've been using. In his book 'Directing the Documentary', Michael Rabiger asks filmmakers to take the time and write a bit starting with the sentence 'What I believe'. The best way to do this is set your timer for ten, fifteen minutes and just type as much as you can. It's quite cool, cos then you end up with a sort of manifesto that's all yours. So when it comes to developing characters, it can be eye-opening to do this for them. You can do it in the third person (I tend to do this if the story they feature in is third person) and you end up with 500 words and hopefully a deeper understanding of their outlook and beliefs. One thing I'd recommend is not doing one for yourself right before you do one for your character because there might be too much overlap. Hope someone finds this useful!
