Former New York bomb squad detective Denis Mulcahy is credited with saving countless children's lives during the Troubles and is the subject of a new documentary narrated by Liam Neeson.
Denis founded Project Children during the darkest days of violence in Northern Ireland, bringing young people from both sides of the divide to the United States for peaceful summers.
During the course of 40 years more than 20,000 children from some of the worst-hit areas of Belfast and Derry spent six-week stints with American host families, far from bomb blasts and riots.
The tale of how Cork native Mr Mulcahy launched Project Children with willing family and friends in 1975, is told in the feature film How to Defuse A Bomb: The Project Children Story.
How To Defuse A Bomb: The Project Children Story is part-funded by the BBC and is due to be broadcast later this year.
