A dramatisation of the Irish civil rights protest march and subsequent massacre by British troops on 30 January 1972.
Ballymun in north Dublin is transformed into Derry 1972 as the area becomes the set for a forthcoming film about the events of Bloody Sunday.
Hundreds of extras play the roles of British paratroopers and civil rights protesters in the production by Granada Films.
The set included a recreation of the famous gable wall with the message
You Are Now Entering Free Derry
The film was written and directed by Paul Greengrass and stars James Nesbitt as Ivan Cooper, one of the founding members of the Social Democratic and Labour Party (SDLP).
An RTÉ News report broadcast on 25 March 2001.
