When founder and (now former) chief archivist at the Walt Disney Archives Dave Smith went on a search for the snowglobe from this movie, which featured birds flying around Saint Paul's Cathedral, he finally found it on a shelf in a janitor's office. The janitor explained that he saw the snowglobe sitting in a trash can, but found it too pretty to throw away and kept it himself.
Walt Disney cast Dame Julie Andrews for the lead after seeing her in "Camelot" on Broadway. When she mentioned she was pregnant, he offered to wait until she had her baby to start filming and offered her then-husband, Tony Walton, the job of designing costumes and some sets for this movie. Disney also gave the couple a personally escorted tour of Disneyland and the studio to help them make up their minds. Disney liked Andrews in "Camelot" so much that after he saw her performance, he had the animators of "One Hundred and One Dalmatians" draw the character of Anita to resemble her.
