 The film's name comes from Claire Rogan's (widow of Aidan Rogan) statement that police had assured the families they would leave "no stone unturned" in the investigation.Their daughter Emma Rogan—later a Member of the Legislative Assembly (MLA) for South Down—said the film would be "a permanent memory to the victims and the injustice done".Gibney had earlier directed a shorter documentary about the massacre, named "Ceasefire Massacre", broadcast on 29 April 2014 by ESPN, as part of their "30 for 30" series.
