The fourth season of Noah Hawley’s highly acclaimed FX series “Fargo” was a notable casualty of the pandemic as production shut down back in March with only two episodes left to be shot. A couple of weeks ago, the team behind the series started up again, trying to bring this year’s story in for its final chapter with a heavy amount of protective precautions designed to make that as likely as possible. Will viewers be able to tell? Probably not. But an even worse possibility is if the final episodes of this season somehow have to come to a halt again because of an outbreak. It must be tense on that set right now.
