VIDEO: New Trailer for BEGIN AGAIN, With Knightley, Ruffalo, Corden, Levine & More

The latest film from writer-director John Carney (ONCE), BEGIN AGAIN is a soul-stirring comedy about what happens when lost souls meet and make beautiful music together. Below, watch a new trailer for the film, featuring Keira Knightley, real-life pop stars Adam Levine and CeeLo Green, THE NORMAL HEART's Mark Ruffalo and stage vet James Corden!

In BEGIN AGAIN, Gretta (Keira Knightley) and her long-time boyfriend Dave (Adam Levine) are college sweethearts and songwriting partners who decamp for New York when he lands a deal with a major label. But the trappings of his new-found fame soon tempt Dave to stray, and a reeling, lovelorn Gretta is left on her own. Her world takes a turn for the better when Dan (Mark Ruffalo), a disgraced record-label exec, stumbles upon her performing on an East Village stage and is immediately captivated by her raw talent. From this chance encounter emerges an enchanting portrait of a mutually transformative collaboration, set to the soundtrack of a summer in New York City.

BEGIN AGAIN is produced and financed by Exclusive Media and produced by Anthony Bregman, Tobin Armbrust and Judd Apatow.
