In an interview, the Russos explained that they start with a three-page story document, which leads to the full script later on. They explained, “Basically, the first page is Act 1, the second page is Act 2 and the third page is Act 3. [...] Once we do that three-pager, we go to a 10-pager where we start to infuse character and thematics, and we do some sample dialogue.”
