Inside Llewyn Davis, the new film written and directed by Joel and Ethan Coen, opened in select theaters in New York and Los Angeles this past weekend, to critical acclaim and box office success, and has continued to earn accolades. The film was named one of the Top 10 Films of the Year by the American Film Institute, won the Best Use of Music Award from the New York Film Critics Online, and has been nominated for six Online Film Critics Society awards and the Los Angeles Film Critics Award for Best Music Score. Inside Llewyn Davis expands to additional theaters across the US on December 20.

A new, four-minute featurette on the casting of Inside Llewyn Davis, including behind-the-scenes footage and interviews with the Coen brothers and cast members Justin Timberlake, Carey Mulligan, John Goodman, and Garrett Hedlund, premiered on The Hollywood Reporter. Watch it here:

Oscar Isaac, who plays the title role of Llewyn Davis, was a guest on Late Night with Jimmy Fallon on NBC last night. Isaac and Fallon discussed the new film and the unusual circumstances behind their first meeting at the London 2012 Olympics. Isaac also performs a unique take on Katy Perry's "Roar." You can watch both the interview and the performance below.
