Although based on historical events , the film does contain some alterations and fictionalisations , such as the dramatised circumstances of Harry Boland 's death and Ned Broy 's fate , and significant altercations to the formative years of Dáil Éireann and the prelude to the events of the first " Bloody Sunday " at Croke Park . Neil Jordan defended his film by saying that it could not provide an entirely accurate account of events , given that it was a two-hour film that had to be understandable to an international audience who would not know the minutiae of Irish history . The documentary on the DVD release of the film also discusses its fictional aspects
