Mary Poppins is a 1964 American musical fantasy comedy film directed by Robert Stevenson and produced by Walt Disney, with songs written and composed by the Sherman Brothers. 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.

Musical film is a film genre in which songs by the characters are interwoven into the narrative, sometimes accompanied by dancing. The songs usually advance the plot or develop the film's characters, but in some cases, they serve merely as breaks in the storyline, often as elaborate "production numbers".
