Here’s the first trailer for Clint Eastwood‘s adaptation of the Tony-winning Broadway smash about legendary early-rock group the Four Seasons. Warner BrosJersey Boys has taken a serpentine road to the big screen. It originally was at Sony before Graham King signed a multi-year deal with Warners in September 2012 and moved the project over with him. John Lloyd Young — who won a Tony for his role as Frankie Valli — Erich Bergen, Michael Lomenda and Vincent Piazza star as the boys in the band, with Christopher Walken playing a notorious mobster.
