Sat down and watched a behind the scenes featurette for Breaking Bad where they talked about mapping out Walter White's entire arc on a huge whiteboard before they even cast Bryan Cranston. They knew exactly where they wanted him to end up by season 5. It's wild to think about because most shows seem like they're just making it up as they go. Dark sounds insane though. 900 pages just for the timeline alone. That's the kind of dedication that makes a show actually hold up when you rewatch it.
