The French château that appears in the film was constructed especially for the production by art director William Hutchinson and his crew of eighty-five. One of the largest sets ever built, it stood 240 feet across and 50 feet high. Gardeners surrounded the building with 5,400 square yards of heather, 400 ferns, 450 shrubs, 30 spruce trees, and six full-grown weeping willows.
