Justin Timberlake has revealed that he recently spent some time in the studio with Mumford & Sons frontman Marcus Mumford creating music that will be featured in the upcoming Coen brothers film, Inside Llewyn Davis.

"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," Timberlake tells the U.K.'s Capital FM. "So not only will that be a great movie, but the music to it will be fantastic.”

According to IMDb.com, Inside Llewyn Davis is about “a singer-songwriter [who] navigates New York's folk music scene during the 1960s.”  In addition to Timberlake, Inside Llewyn Davis also stars Oscar Isaac, Garrett Hedlund, John Goodman and Mumford’s wife, Carey Mulligan. The film does not yet have a release date.
