Watch: Keira Knightley in first trailer for 'Begin Again'

The first trailer and poster for Keira Knightley's upcoming film Begin Again (formerly titled as Can A Song Save Your Life? In theaters July 4th) with Mark Ruffalo and Adam Levine has just been released today.

Here’s the official synopsis for Begin Again:

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. 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.
