Joel and Ethan Coen have been remarkably successful working together, from Oscar hits like “Fargo” and “No Country for Old Men” to cult classics like “The Big Lebowski,” thanks in part to a long track record of finding talent. With “Inside Llewyn Davis,” in theaters Dec. 20, the brothers are back directing a bright new star, Oscar Isaac, who transitions from an oft-used side character to a leading man to play a talented, yet deeply flawed folk singer struggling in New York City’s Greenwich Village in 1961. Watch a BDCwire exclusive interview with Isaac, where he discusses learning new guitar picking styles for the role and confesses to his blue-haired ska band roots.

So what can we expect from “Inside Llewyn Davis,” which also stars Carey Mulligan, John Goodman, Garrett Hedlund, and Justin Timberlake? Out of the 21 films that the Coen brothers have collaborated on, they have only co-directed eight films. But in recent years, their directorial partnership has won them praise and awards. “Inside Llewellyn Davis” seems to follow suit: Earlier this month, the film surprisingly beat out critics’ favorite “12 Years a Slave” to take home best feature at the Gotham Awards. Can someone say Oscars?
