This week, Elvis Mitchell sits down with Noah Hawley, the executive producer and showrunner of the FX series ‘Fargo.’ The series debuts its fourth incarnation this month. It’s set in the 1950s and stars Chris Rock and Jason Schwartzman as members of rival crime families. Hawley talks about how faith and allegories have often informed the storytelling of the series and how he can tell when a story will pass a Coen Brothers’ test.
