The latter scenes, where the Mother is digging in the soil, were filmed at the Aberfan Memorial Garden. The Garden is located on the site of Pantglas Junior School, which was destroyed in the Aberfan Disaster on 21st October, 1966; killing 116 children and 28 adults. All of the children and the vast majority of the adult victims, were caught in a landslide of coal waste that engulfed the school.
The Aberfan Disaster forms the backdrop to the film's story.
