Nine years after "Jersey Boys" opened on Broadway and swept through the Tony Awards, the first trailer for the Clint Eastwood-directed film adaptation has arrived. The jukebox musical about Frankie Valli and the Four Seasons' rise and fall stars John Lloyd Young, who won a Tony for his portrayal of Valli in the original Broadway cast. Up-and-coming actors -- including Vincent Piazza, best known for portraying Lucky Luciano on "Boardwalk Empire" -- play Valli's bandmates.

Faithful to the stage production, the film maintains the prominent shattering of the fourth wall. But, because this is an upbeat rags-to-riches musical directed by the ever-macho Eastwood, there's an emphasis on the gritty New Jersey setting and the bandmates' turmoil. Oh, and Christopher Walken is thrown in as Gyp DeCarlo, the 1960s mob boss who got the Four Seasons out of a tight spot through lead guitarist Tommy DeVito. Yep, this is an Eastwood movie, all right.
