Back in 2006, Once announced itself to the world as a heart-warming tale of music and love in the heart of Dublin, winning itself an Oscar for Best Original Song and confirming John Carney as a talented director.

Having scored national success with Bachelor's Walk, Once put him on an international stage. He followed this up with Begin Again, another music-based story set in New York and featured a cast that included Adam Levine, Mark Ruffalo and Keira Knightley. The film performed well overall and secured itself a nomination for Best Original Song.

With Sing Street, Carney's returned to Dublin, although set himself firmly in the '80s and, in a way, his own life. We talked to John about the period detail of the film, making an Irish film for an audience, working with untested actors and what he makes of both the Irish film industry and the wider music industry itself.
