Specifically, the film crew used locations in:
* The Brecon Beacons National Park: This area provided the stunning Welsh scenery, including the dramatic mountain ranges and valleys.
* Blaenavon: The historic industrial town served as the backdrop for many scenes in the film, particularly those depicting the mining village.
* Pontardawe: The village was used for several key scenes, including the opening sequence where the Morgan family walks through the valley.
While some scenes were shot on sound stages, the vast majority of the film was captured on location in Wales, giving it a strong sense of authenticity and capturing the beauty of the Welsh landscape.
