Mary Poppins Premiere

Mary Poppins was released on August 27, 1964, to universal critical acclaim and commercial success, earning $44 million in theatrical rentals in its original run. It became the highest-grossing film of 1964 in the United States, and at the time of its release became Disney's highest-grossing film. During its theatrical lifetime, it grossed over $103 million worldwide. It received a total of thirteen Academy Award nominations—a record for any film released by Walt Disney Studios and Walt Disney Cartoons—including Best Picture, and won five: Best Actress for Andrews, Best Film Editing, Best Original Music Score, Best Visual Effects, and Best Original Song for "Chim Chim Cher-ee". In 2013, it was selected for preservation in the United States National Film Registry by the Library of Congress as being "culturally, historically, or aesthetically significant."

The screenplay is by Bill Walsh and Don DaGradi, based on P. L. Travers's book series Mary Poppins. The film, which combines live-action and animation, stars Julie Andrews, in her feature film debut, as Mary Poppins, who visits a dysfunctional family in London and employs her unique brand of lifestyle to improve the family's dynamic. Dick Van Dyke, David Tomlinson, and Glynis Johns are featured in supporting roles. The film was shot entirely at the Walt Disney Studios in Burbank, California, using painted London background scenes.

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.

A biographical drama based on the making of the film, Saving Mr. Banks, was released in 2013. A sequel to the original film, Mary Poppins Returns, was released in 2018
