Based off the hit Broadway play, Warner Bros.' Jersey Boys gives fans of Frankie Valli and The Four Seasons new insight into how these former delinquents from New Jersey used music to turn their lives around and reach the top of the charts. With just two weeks left until the musical biopic hits theaters, Warner Bros. has released a five-minute behind-the-scenes featurette, which gives fans new insight into their rise to fame, along with footage from the set and interviews with director Clint Eastwood, John Lloyd Young (Frankie Valli), Erich Bergen (Bob Gaudio), Michael Lomenda (Nick Massi), Vincent Piazza (Tommy DeVito), Christopher Walken (Angelo 'Gyp' DeCarlo) and several other cast members who discuss their characters and how the production came together smoothly under Clint Eastwood's direction. In addition, we also have a new photo gallery to check out below the featurette.
