Once writer-director John Carney brings us freewheeling charm, seat-of-pants energy and great songs once again in Begin Again, the story of a down-in-the-dumps singer-songwriter (Keira Knightley) and a burnt-out record executive (Mark Ruffalo) who rediscover their love of life by working together.

Begin Again never gets too slick or too soppy, and in Knightley and Ruffalo the pairing is unlikely but just right.

It will do your heart good - let's just call this the feelgood hit of the summer. 

Here the two stars and co-star James Corden talk about making the film.
