The film is clearly set in a border seaside fishing village in Ireland. However, Kathleen is clearly seen voting in the Fermanagh-South Tyrone by-election: a completely land-locked constituency.
The Parachute Regiment are shown wearing maroon berets. They would have had helmets on duty in "Bandit country".
Outside the prison you can clearly see an Austin Metro Mk2 which was not released till late 1984. This film is based in 1981.
