To make this movie as authentic as possible, no lights were used in the movie and the camera work was entirely hand-held
Ruled ineligible to compete for an Oscar in 2003 because it was shown on Irish and British television on the same night that it premiered in a London theater, a violation of the motion picture academy's Rule 3, which requires a six-month wait between the time it is shown in theaters and the time it is shown on TV.
As Ivan Cooper exits home, a theater can be seen, where the movie Domenica maledetta domenica (1971), which was actually showing at the time, is showing.
Three days after this movie's UK television broadcast, Sunday (2002) aired on TV, which chronicled the same event from an alternate perspective.
Shot in the Ballymun district of Dublin, an underprivileged area that bore many resemblances to Derry in 1972. Some incidental scenes involving Derry landmarks were however shot in the city itself.
