Once is the inspirational tale of two kindred spirits who find each other on the bustling streets of Dublin. One is a street musician who lacks the confidence to perform his own songs. The other is a young mother trying to find her way in a strange new town. As their lives intertwine, they discover each other's talents and push one another to realize what each had only dreamt about before. Once is their inspiring story.Written and directed by John Carney (On The Edge, Bachelors Walk), Once is a nod to the classic musicals of the past, while it is also grounded in the bohemian world of struggling young Dubliners that he knew from his days as a young musician. Once is produced by Martina Niland and executive produced by David Collins with music by Glen Hansard and Marketa Irglova.
