Michael Gallagher, whose son Aidan (Paul Kelly) was killed in the bombing, is played by Gerard McSorley, originally from Omagh. Out of respect for the residents of Omagh, it was filmed on location in Navan, County Meath in the Republic of Ireland.
The film ends with the Julie Miller song Broken Things, which was performed by local singer Juliet Turner at the memorial for the victims of the Omagh bombing.
