Watch: First Trailer For Clint Eastwood's Oscar-hopeful 'jersey Boys' Asks 'who Loves You'

Clint Eastwood's output as of late has been pretty uneven: for every triumph ("Letters from Iwo Jima"), there's a major disappointment ("J. Edgar") or outright dud ("Hereafter"). When given great material, though, Eastwood can really make it shine, and there's some potential in his adaptation of the hit musical "Jersey Boys," which just released its first trailer. Eastwood's first musical as a director (following his aborted attempt to remake "A Star is Born" with Beyonce), "Jersey Boys" tells the story of the Four Seasons (later known as Frankie Valli and the Four Seasons) as they went from rags to riches, and as their personal troubles became greater, including debts, mob involvement, strained friendships, and Valli's relationship with his troubled daughter. The pedigree here is huge: the jukebox musical won three Tony Awards, including Best Musical and Best Actor for John Lloyd Young (who reprises his role as Valli here).
