Mary Poppins

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.

The robin that lands on Mary's finger in the "Spoonful of Sugar" sequence is an American robin (Turdus migratorius), not a British robin (Erithacus rubecula).

In the end credits cast list, the actor playing Mr. Dawes, Sr. is initially shown as NAVCKID KEYD, then the letters unscramble themselves to show that this is a second role played by Dick Van Dyke.

An airing on ABC in 2002 played it completely intact with the exception of a scene in which Admiral Boom refers to the nannies waiting to be interviewed as a "ghastly looking crew".
