After pretty much everybody fell in love with Once, director John Carney went away for a few years. But, thankfully, he hasn't been idle in the interim as his new film, Begin Again, looks like it could be another sleeper hit for him. Keira Knightley plays a young musician who's unceremoniously dumped by her boyfriend (Maroon 5's Adam Levine) and has a chance encounter with troubled record executive Mark Ruffalo. The two then decide to work together to create an album that's recorded on location with, well, the surrounding environment being a factor.

It's all very cute and "soul-stirring" and Knightley looks like she can handle a guitar well. Adam Levine acting, however, we're not entirely sure.

Take a look at the trailer and judge for yourself!
