Filmmaker Rebecca Miller knew it would be impossible for her to make a feature-length documentary about Oscar-winning director Martin Scorsese. “There was no way I could go as deep as I wanted to go in one-and-a-half or two hours,” she said. Maybe she could plan for a two-part series. But as she started to interview Scorsese — in addition to numerous collaborators, family members and close friends — it became clear that two parts still wouldn’t be enough. So the documentary stretched into three. Then four. Finally, Miller landed on a total of five episodes, each with its own emotional arc.
