Adapted from the hugely successful stage musical, Jersey Boys follows the ups and downs of what would become the Four Seasons. Onstage, it's a story told through four sections themed around each of the seasons of the year, and narrated by each member of the band in turn. Tommy DeVito, Bob Gaudio, Nick Massi and Franki Castelluccio (also known as Valli) all take their turn to discuss their rise, fall and rise again. On screen, that has been transformed into the guys talking to camera to explain their side of events.
Eastwood has recruited relative unknowns for the band members, with John Lloyd Young, Erich Bergen, Michael Lomenda and Vincent Piazza taking the leads, but he also has Christopher Walken (Seven Psychopaths) in for support, with a script that has seen work from John Logan and the musical's creators, Marshall Brickman and Rick Elice.
Jersey Boys will walk like a man into our cinemas on 20 June.
