The following is an excerpt from 'Fargo' TV miniseries gets second season on FX with new cast
The TV version of "Fargo," which airs internationally, is a reimagining of the blood-soaked black comedy film of the same name by brothers Joel and Ethan Coen.
The miniseries features a different "true crime" story and characters but a large dose of frigid Minnesota and Midwestern folksiness. The Coen brothers are producers but remained largely in the background of the production run by Noah Hawley.
The earliest the second season of "Fargo" will air will be a year from this fall, Landgraf said.
"We haven't worked out the timing of production, but the scripts are already well in progress," he said, adding that he hoped they would film again in Canada.

The following is an excerpt from 'Fargo' Gets 2nd Season on FX With New Cast, Crime
FX is taking another trip to "Fargo," where the cast is changing but some of the characters are not.
The network announced Monday that it has renewed the series for a second season with new actors, time period and crime.
Executive Producer Noah Hawley told a TV Critics' panel that season two will be set primarily in North Dakota in 1979 with a younger version of the Lou Solverson character (played by Keith Carradine in season one.) His daughter, Molly, who Allison Tolman portrayed, is just 4 years old.
Hawley said he's open to changing the weather and is toying with starting the story in the winter and transitioning to spring and summer.
The earliest the series will air is fall 2015.
