New trailers this week include two dramas about young musicians. If I Stay is about a gifted cellist who's in a life-changing car crash. It stars Chloe Grace Moretz, Jamie Blackley, Liana Liberato and Mireille Enos, opens in August and looks pretty warm and wrenching. Watch 'If I Stay' Trailer.

And from Once writer-director John Carney, Begin Again is about a young singer-songwriter trying to make it in Manhattan. Out in July, it looks lively and energetic, and stars Keira Knightley, Mark Ruffalo, Hailee Steinfeld, James Corden and musicians Adam Levine, CeeLo Green and Mos Def. Watch 'Begin Again' Trailer.

But the biggest trailer of the week was an epic new view of X-men: Days of Future Past, the whizzy time-travel blockbuster that combines the cast of First Class with the original trilogy. It looks pretty mind-bending, and very exciting, and opens in just a few weeks. Watch 'X-men: Days of Future Past' Trailer.

And finally, we also got our first look at Clint Eastwood's film of the hit Broadway play Jersey Boys, the stylish, classics-filled story of the turbulent rise to fame of the iconic pop group The Four Seasons in 1960s New Jersey. Christopher Walken leads the cast for the film, which is out in June. Watch 'Jersey Boys' Trailer.
