On a night in June 1994, six men were shot and killed while watching the Football World Cup at their local Loughinisland pub in Northern Ireland. This event, and the following decades, are the subject of a new documentary film from Alex Gibney.

Sean chatted to the producer of the documentary, Trevor Birney, about the significance of the events that night, what the film means for the families of the victims and how it has been received by audiences worldwide.

No Stone Unturned is screening on Saturday 21st April at Palace Chauvel as part of the Irish Film Festival.
