The film "The Woman in Cabin 10" was primarily filmed aboard a real superyacht named Savannah, which is over 273 feet long and built by the Dutch company Feadship. The yacht was docked in Portland Harbour near the Isle of Portland in Dorset, England, one of the largest artificial ports in the world, and served as the main location for both interior and exterior scenes of the yacht in the film. Additional filming for surrounding water scenes took place in Portland Harbour, which doubled as the ocean setting. Other sequences were filmed on location in Norway, specifically Hjørundfjorden fjord, and in Glen Affric, Scotland. Interior scenes not filmed on the yacht were recreated on a soundstage in Shepperton Studios in England.
