Joel and Ethan Coen's long-awaited follow-up to True Grit is a drama set in the New York folk music scene of the early Sixties, the milieu of Bob Dylan, Joan Baez, Ramblin' Jack Elliott and Dave Van Ronk (whose memoir, The Mayor of MacDougal Street, is the screenplay's primary source). Oscar Isaac stars as the title character, a folkie who arrives in Manhattan in 1961 and tries to navigate the treacherous waters of the Greenwich Village coffeehouse scene. Along for the ride are Isaac's Drive co-star Carey Mulligan, John Goodman, On the Road's Garrett Hedlund and Justin Timberlake. The film may have a tongue-in-cheek view of the era's personalities, but it will take the music itself seriously. T Bone Burnett, who curated the landmark roots-music soundtrack for the Coens' O Brother, Where Art Thou?, pulls the same duty here, with the help of Timberlake and Mumford & Sons' Marcus Mumford (who is also Mulligan's real-life husband). The movie will be released in the U.S. in December.
