Inside Llewyn Davis is a 2013 American drama film written, directed, produced and edited by Joel and Ethan Coen. Set in 1961, the film stars Oscar Isaac in the title role as a New York City folk singer, Carey Mulligan, John Goodman, Garrett Hedlund, F. Murray Abraham, and Justin Timberlake. The film follows one week in the life of Llewyn Davis, a folk singer struggling to achieve musical success while keeping his life in order.
