 This was one of the earliest uses by a British studio.With only one small hotel on the island, the cast were housed with the islanders, which had the advantage that it helped the actors pick up the local accent for the film.One local, who was adept at Scottish dancing, stood in as the body double for Greenwood in the "rèiteach" scene; Greenwood, a talented ballet dancer, could not master the steps of the reel, and the feet of one of the islanders were filmed.
