Justin Timberlake is trading Timbaland bump for lumberjack chic on a forthcoming OST project for the Coen Brothers.

Timberlake has a role in the Coens’ forthcoming film Inside Llewyn Davis, starring Carey Mulligan and John Goodman. Speaking to Capital FM, Timberlake revealed that he is also working on the score for the record. His principal collaborator? Marcus Mumford of Grammy-guzzling combo Mumford & Sons:

“OK I can tell you this. There’s a Coen Brothers film coming out soon that I was lucky enough to work with Oscar Isaac and Carey Mulligan. And coincidentally I did work with Marcus Mumford on the soundtrack, so I became very good friends with them. Marcus and myself, we all kind of worked on the music together and I don’t know any other world where we would have the opportunity to collaborate like that but it was so much fun. So not only will that be a great movie, but the music to it will be fantastic.”

Timberlake’s recent film roles include 2011 rom-com Friends With Benefits and a turn as Napster founder Sean Parker in David Fincher’s 2010 masterpiece The Social Network. Fincher has returned the favour by directing the video to Timberlake’s comeback single ‘Suit & Tie’. Timberlake will release new album The 20/20 Experience on March 18. He’s also set to tour with Jay-Z over summer; head here for dates.

Inside Llewyn Davis follows the fortunes of a shiftless 1960s folk singer, based on Greenwich Village folk singer Dave Von Ronk. A trailer for the film is below.[via Consequence Of Sound]
