“Inside Llewyn Davis”
Joel and Ethan Coen won the Palme d’Or with “Barton Fink” 22 years ago, while “Fargo” and “The Man Who Wasn’t There” also picked up best-director awards at Cannes. They could mine a (typically twisted?) vein of nostalgia with this look at the 1960s Greenwich Village folk scene, with a lead character loosely based on Dave Van Ronk.
