Here is a nice little snippet:
Garret Dillahunt: When you get something like that, you just want to focus. Everybody comes to work focused. People hung out at “Deadwood.” People came to work when they weren’t called. You just wanted to be there because something special was happening. What made it special might have killed it, ultimately. I don’t know. I would be guessing. We took 21 days to finish an episode one time. No network can stomach that. We made sure it was right. The crew was like Spartan f–king warriors slogging through red mud with all this equipment. I’m sure [everyone] could have made more money on a network show or something, but everyone was proud. They were really proud of what they were doing. I felt in such good hands and in good company there. When there’s this mix of people who are like-minded in their goal, something spectacular happens.
I think everything’s an ensemble piece, whatever anyone else says. “Deadwood” made me want to equal that experience as often as I could. It’s more in your control than you might think. You’re not going to run into someone that can do dialogue like David Milch that often. But you can behave on a set in the same way. It’s something I always look for and it’s always been my favorite experiences… “No Country for Old Men,” “The Assassination of Jesse James by the Coward Robert Ford,” these movies that I’ve done that had that same feeling of collaboration. It’s collaboration, not cooperation even. We’re working together; it doesn’t mean it’s painless. It doesn’t mean there aren’t arguments. I’m not talking about a commune. I just mean everyone is here for one purpose, to tell this story, this particular story, as well as we can. That was certainly true on “Deadwood,” from my perspective anyway.
