Development The film's main basis was the first novel in
the Mary Poppins series. According to the 40th Anniversary DVD release of the film in 2004, Disney's daughters fell in love with the
Mary Poppins books and made Disney promise to make a film based on them. He first attempted to purchase the film rights from
P. L. Travers as early as 1938, but Travers repeatedly refused; she did not believe a film version would do justice to her books. Disney was also then known primarily as a producer of animated films, and had yet to produce a major live-action work. For more than 20 years, he made periodic efforts to convince Travers to release the rights, including visiting her home in
Chelsea, London. He finally succeeded in 1961, although Travers demanded and obtained script-approval rights. The
Sherman Brothers composed the music score and were involved in the film's development, suggesting the setting be changed from the 1930s to the
Edwardian era. Pre-production and music creation took about two years.
Pre-production Travers was an adviser to the production, and was billed as the film's consultant. However, she disapproved of the dilution of the harsher aspects of Mary Poppins' character, felt ambivalent about the music, and hated the use of animation so much that she ruled out any further adaptations of the later
Mary Poppins novels. She objected to a number of elements that made it into the film. Rather than original songs, she wanted the soundtrack to feature known standards of the Edwardian period in which the story is set. However, due to contract stipulations citing that he had
final cut privilege on the finished print, Disney overruled her. In a 2013 interview, Dick van Dyke said that Travers felt that neither he nor Julie Andrews were right for the lead roles. Much of the Travers–Disney correspondence is part of the Travers collection of papers in the
State Library of New South Wales, Australia. The relationship between Travers and Disney is detailed in
Mary Poppins She Wrote, a biography of Travers by Valerie Lawson. The biography is the basis for two documentaries on Travers:
The Real Mary Poppins and
The Shadow of Mary Poppins. Their relationship during the development of the film was also dramatized in the 2013 Disney film
Saving Mr. Banks.

Mary Martin in the film.

Cary Grant,
Jamie Farr, and
Andy Griffith. Before

Julie Andrews, who was making her feature film acting debut after a successful stage career, was given the prime role of Mary Poppins soon after she was passed over by
Jack L. Warner and replaced with
Audrey Hepburn for the role of
Eliza Doolittle in his
screen adaptation of
My Fair Lady, even though Andrews originated the role on Broadway. When Disney approached Andrews about playing Poppins, she was three months pregnant. Disney assured her that they were willing to postpone filming until she had given birth so that she could take the part. Disney considered actor
Stanley Holloway for the role of Admiral Boom, but it went to Reginald Owen, due to Holloway's commitment to
My Fair Lady. Andrews also provided the voice in two other sections of the film: During "
A Spoonful of Sugar", she provided the whistling harmony for the robin and she was also one of the
Pearly singers during "Supercalifragilisticexpialidocious".
David Tomlinson, besides playing Mr. Banks, provided the voices of Mary's talking umbrella, Admiral Boom's first mate, and numerous other voice-over parts. During the "Jolly Holiday" sequence, the three singing Cockney geese were all voiced by
Marni Nixon, who regularly sang for actresses with substandard singing voices. (Nixon later provided the singing voice for Hepburn in
My Fair Lady and played one of Andrews's fellow nuns in
The Sound of Music.) Andrews later beat Hepburn for the
Best Actress Award at the
Golden Globes for their respective roles. Andrews also won the
Oscar for Best Actress for her role (Hepburn was not nominated for it). Richard Sherman, one of the songwriters, also voiced a penguin and one of the Pearlies. Robert Sherman provided the speaking voice of Jane Darwell because Darwell's voice was too soft to be heard in the soundtrack. He is heard saying the only line: "Feed the birds, tuppence a bag." Disney cast
Dick Van Dyke in the main supporting role of Bert after seeing his work on
The Dick Van Dyke Show. After winning the role, Van Dyke lobbied to also play the senior Mr. Dawes. Disney felt he was too young for the part, but Van Dyke won him over after a screen test. Van Dyke had trouble with Bert's Cockney accent. English character actor
J. Pat O'Malley provided some coaching; but although Van Dyke is fondly remembered for the film, his
attempt at a Cockney accent is considered one of the poorer accents in film history. (It was #2 in a 2003 poll by
Empire magazine of the worst film accents.) Van Dyke claimed that O'Malley "didn't do an accent any better than I did". In 2017, Van Dyke received an award for television excellence from the
British Academy of Film and Television Arts (BAFTA), at which time he said, "I appreciate this opportunity to apologise to the members of BAFTA for inflicting on them the most atrocious cockney accent in the history of cinema." A chief executive of BAFTA responded, "We look forward to his acceptance speech in whatever accent he chooses on the night. We have no doubt it will be '
supercalifragilisticexpialidocious'."
Filming Filming took place between May and September 1963 in Burbank, California; post-production and animation took another eleven months. . The scene in which Mary Poppins and Bert interact with a group of animated penguins is noted for its use of the
sodium vapor process. Rather than using the more common
bluescreen process to insert the actors into the animated footage, the actors were filmed against a white screen lit with sodium vapor lights, which have a yellow hue. A special camera was fitted with a prism that filtered this light to a separate reel of film, creating a highly accurate matte that could be used to isolate the actors from the background. This created a crisp, clean image and even allowed the partially transparent veil of Mary Poppins's costume to let through light from the background. The film received the
Academy Award for Best Visual Effects in 1965 for this effect.
Peter Menefee, one of the 12 dancing chimney sweeps supporting Bert, provided some insight into the film's choreography: The film's choreographers were
Dee Dee Wood and her husband
Marc Breaux. Walt Disney attended the rehearsals for the rooftop scenes every day. == Music ==
