‘Jersey Boys’ Trailer: Clint Eastwood Returns to His Musical Roots

Of the many hats Clint Eastwood has worn over the course of his nearly six decades-long career in show business — yep, he nabbed his first acting gig 59 years ago — his status as a musician is perhaps the most pleasantly surprising (and at times a bit chuckle-worthy) to explore.

See, Dirty Harry's been dabbling in song for ages, ever since his earliest days as a young TV western star who was tapped to create an album of himself belting out a few "Cowboy Favorites." (No joke.) The little-known fact of the matter is that Eastwood has actually got a rather formidable discography to his name, having composed the scores to a handful of his films and writing and/or performing a ton of soundtrack contributions over the years.

Now the multiple Oscar-winning director continues that melodic tradition in a new capacity, presenting some musical drama action all his own.

His "Jersey Boys," the first trailer for which has just been released, is an adaptation of the popular, Tony-winning Broadway show of the same name, showcasing the rise and fall of Franki Valli and the Four Seasons, a group known for some of the most unique vocal stylings ever to come out of the 1960s doo-wop scene.

The signature sound of Valli's high-pitched voice made them one of the era's most iconic; even a simple recalling of their most famous titles ("Walk Like a Man," "Sherry," "Big Girls Don't Cry," etc.) evokes a distinct audible memory.

The film features John Lloyd Young as Frankie Valli, whom he portrayed in the Broadway production as well. The character is a young New Jersey native with a troubled past who links together with three others of his stature (Vincent Piazza, Erich Bergenn, and Michael Lomenda) to form the Seasons.

As with the stage iteration, the movie will chronicle the formation, massive successes, and eventual dismantling of the group along with its ties to a mafioso called "Gyp" (portrayed by Christopher Walken).

While this is Clint Eastwood's first directorial effort at a musical movie, he does have some prior experience within the genre, having starred in (and sung for) a 1969 ballad blockbuster called "Paint Your Wagon."

His other movie musician credits include serving as composer on a half dozen of his own movies ("Mystic River," "Million Dollar Baby," "Flags of Our Fathers," "Changeling," "Hereafter," and "J. Edgar"), along with James C. Strouse's "Grace Is Gone," and penning and performing dozens of Tinseltown tunes, including Golden Globe-nominated title tracks for "Gran Torino" and "Grace Is Gone."

Even outside of the film scene, the crooner has exhibited a harmonic knack, contributing to country music albums by the likes of Merle Haggard and Brad Paisley. His piano jazz skills were even featured in a live performance at Carnegie Hall back in the late '90s.

Suffice it to say, the obvious audiophile was probably feeling pretty lucky to get behind the camera and put his musical knowledge to good use for this "Jersey Boys" adaptation.

The film hits theaters on June 20.
