A new trailer for the Coen brothers' film, Inside Llewyn Davis, was released today.

The trailer features Llewyn's (Oscar Isaac) interactions with various characters in the film, which stars John Goodman, Justin Timberlake, and Carey Mulligan.

Set in the Sixties coffee-house folk scene of New York, the film garnered rave reviews at the 2013 Cannes film festival, winning the Grand Prix Award. It is loosely based on Dave Van Ronk's book, the Mayor of MacDougal Street. Capturing New York's Sixties cityscape and landmarks of Greenwich Village, the film's rustic score was overseen by Marcus Mumford (Mumford and Sons), T Bone Burnett, and Timberlake. The film follows a week in the life of struggling musician, Llewyn, in wintry New York.

Isaac (Drive, Won't Back Down), the Guatemalan-American actor who is also a singer, talked about playing the protagonist of the film in an interview with the Guardian:

"Being celebrated for playing someone who wasn't. Llewyn is like the Jesus character who had to be sacrificed for our sins. I get quite emotional about it. It's hard not sounding like a douchebag because it's like: 'Oh, I've been so successful for those poor people that haven't.' But I know those people; it could have easily just gone the other way for me too. There's very few people - like Shakespeare - who, no matter what, were gonna do what they did. For the rest of us there's a lot of events that have to happen in order for things to end up the way they are."

The film's primary cast is completed by Sands and Garrett Hedland (On the Road). It also features Girls stars Adam Driver and Alex Karpovsky in smaller roles.

The film will have a limited release on December 6, and a proper release on December 20. Inside Llewyn Davis will also be screened at the upcoming New York Film Festival.

A special benefit concert inspired by the film, will take place on Sep. 29 at the Town Hall in New York.

The concert will feature performances by the Avett Brothers, Patti Smith, Colin Meloy (the Decemberists), Mumford (the Mumford and Sons), Jack White, Conor Oberst, and Gillian Welch & Dave Rawlings. Stars from the film, Isaac, Mulligan, Goodman, and Sands will also be present at the concert.

Joel and Ethan Coen, and Burnett are producing the event, with some proceeds benefiting the National Recording Preservation Foundation. Tickets go on sale Aug. 21.
