 SPOILER: The oil rigs name was Gaviota, but Isabel Coixet changed  it into Genefke, for the founder of IRCT (played by Julie Christie),  to whom the movie is dedicated. IRCT is an organization that  promotes and supports the rehabilitation of torture victims and  works for the prevention of torture worldwide. Takes of the oil rig  were shot in Belfast and Bilbao. Interior scenes were filmed in  Navalcarnero (Madrid, Spain).
