Fargo, a perfect 30-year-old thriller, is all about doing your damn job

Fargo is noir turned on its head. Working with the visionary cinematographer Roger Deakins, the Coens expose this usually shadowy genre to the blinding, unforgiving whiteout of the Minnesotan midwinter. Working with the brilliant actor Frances McDormand, the directors swap the typical, tragically doomed femme fatale out for her inverse: a sunny, imperturbable, heavily pregnant police chief, Marge Gunderson.
