One of only five (it being the third) music scores (to date, February 2015) for a full length feature film composed by Northern Irish singer-songwriter and musician Van Morrison.
The film was released five years after its source novel, of the same name, by Bernard MacLaverty, had been published. MacLaverty also penned the screenplay for the movie.
The majority of the children extras and background artists came from both the Bishop Douglass School and the Bodmin Comprehensive School in East Finchley in North London, England.
