Fargo has, by far, been one of the most well-executed adaptations of a movie to a television format.
Noah Hawley smartly ditched the story and kept the overall vibe from the Coens' creation, thus making it seem both familiar and brightly original at the same time. Three seasons in, it's some of the best TV out there and the fourth season looks like it's going to be pretty special as well.
In a lengthy interview with THR, Hawley explained that the idea's starting to come into focus. "More and more as I think about telling stories in this vein and what the original film is about, these are really American stories and stories about the American landscape, and the things that people do for money. I feel like I have a very interesting and exciting direction to go in. I'm trying to find the time to get it down on paper," explained Hawley, who also has commitments to exec-produce FX's Legion, and probably some other stuff that hasn't been announced yet.
On the topic of setting, however, Hawley suggested that it could easily be set in colonial times, saying that "there's a good joke in the idea that the more things change, the more they stay the same. I don't know if there's 10 episodes in that or not! But if you look at the history of the region and the waves of migration and people coming in, and the things people do for money... there's something interesting to making a period version of it."
