When I first talked with Joel and Ethan Coen, they asked what I had planned to do about the characters' Minnesota accents. In the film they had become iconic and such a caricature in our culture that I felt we should really underplay them. They agreed. We wanted something that sounded regional without being so exaggerated. Aside from that, they never gave me any notes. They read the first script, liked it, suggested a few lines and jokes, but that was the sum total of their creative involvement. They said: "Look, we don't know television. It's your show -- just go make it."
When we showed them the first episode, Ethan said, "Yeah, good," which I've since learned is a rave review.
