According to the (always right! ) Wikipedia, what he turned down was a short order of a 6 episode fourth season, but counter-offered to do the two movies. Why he preferred four hours to six kind of puzzles me, but HBO was amenable. Just never happened, is all.
Very frustrated and truly ashame. Especially after reading the behind the scenes book and getting a totally different take on some of the characters, but also knowing that Milch did a LOT of improv on the set, I really would have liked to know where the characters would have gone. If you read about the real Al Swearengen, his final years and life story were pretty darn sad and his death was downright pathetic. I wonder if they would have ever shown that or not. Also, based on what I read in the book, Seth was a MUCH darker character than I felt he was portrayed in the show and I would have liked to have seen where they went with that as well. Guess we will never know, and while I watch "Justified", and see Timothy O trying to channel Seth for Raylan Givens, that show is a far cry from Deadwood.
What book are you all speaking of? I was a a HUGE Deadwood fan, I agree that it is probably the best television show of my time. There are other shows I loved, but it was just amazing!
I always felt that the Bullock near the boiling point was the real character, and should have been present 24/7. I suppose a character like that would have just eventually shot everyone, and not been much of a character at all.
