Based on real stories, using both actors and non-actors, and filmed on location in Dublin, A Week in the Life of Martin Cluxton (1971) is a rare example of Irish social realism. After years in an industrial school, Martin Cluxton (Derek King) returns home to Dublin but finds considerable prejudice and little opportunity. Broadcast on RTÉ, it was directed by Brian MacLochlainn, co-written by Caoimhín Ó Marcaigh and MacLochlainn, with music by jazz great Louis Stewart.
