"For me, I don't start a project unless I have a really clear understanding of who the main characters are and why this is a journey that's necessary for them to take. And why are these both the best and the worst people to be in this series? That's the question I ask myself all the time because you need to know: What are their strengths? What are their weaknesses? What are the dramatic tension points going to be where these specific people can really succeed or really fail in this scenario?"
