Director Zinnemann adapted the story from a novel written by Kathryn Hulme, once a disciple of Gurudjieff, eventually turning Roman Catholic. The novel is based on a real life character, a close friend of Hulme, whose life was close to the film's tale. That lady eventually nursed back Audrey Hepburn to health after a serious accident much later. The film is admirable in some respects but I feel it is not Zinnemann's best. Celebrated Italian director Sergio Leone was an uncredited assistant director to Zinnemann in this film.
