If you haven't read Creativity Inc, on the formation and rise of Pixar by Ed Catmull (one of its founders); you're missing out. As well as a business biography, there are a huge number of philosophical theories on how to best nurture creativity in the film-making process, and how to bring all employees together to make the best product possible.
My Kindle informs me that I've highlighted 35 sections in this book - for non-technical manuals, I usually will make around 2 maximum per book. So, it's fair to say that a lot of it struck a chord.
I'd like to share a short passage on giving meaningful feedback, which applies to many stages in the film-making process, and certainly not just animation. As an editor, I receive a lot of notes - and sometimes send them out, either on cuts I've made or on scripts and films that other people I know are working on.
A good note says what is wrong, what is missing, what isn’t clear, what makes no sense. A good note is offered at a timely moment, not too late to fix the problem. A good note doesn’t make demands; it doesn’t even have to include a proposed fix. But if it does, that fix is offered only to illustrate a potential solution, not to prescribe an answer. Most of all, though, a good note is specific. “I’m writhing with boredom,” is not a good note.
