Alice in Wonderland is a 1951 American animated musical fantasy comedy film produced by Walt Disney Productions and based on the Alice books by Lewis Carroll. The thirteenth release of Disney's animated features, the film premiered in London on July 26, 1951, and in New York City on July 28, 1951. It features the voices of Kathryn Beaumont as Alice, Sterling Holloway as the Cheshire Cat, Verna Felton as the Queen of Hearts, and Ed Wynn as the Mad Hatter. Walt Disney first tried to adapt Alice into a feature-length animated film in the 1930s and revived the idea in the 1940s. The film was originally intended to be a live-action/animated film, but Disney decided it would be a fully animated film.

The film was shown on television as one of the first episodes of Disneyland. The film received generally negative critical reviews on its initial release and was therefore not re-released during Disney's lifetime. However, reception upon its 1974 re-release was positive, leading to subsequent re-releases, merchandising and home video releases.

A computer-animated reboot series, Alice's Wonderland Bakery, premiered on February 9, 2022.

Walter Elias Disney (; December 5, 1901 – December 15, 1966) was an American animator, film producer and entrepreneur. A pioneer of the American animation industry, he introduced several developments in the production of cartoons. As a film producer, he holds the record for most Academy Awards earned and nominations by an individual, having won 22 Oscars from 59 nominations. He was presented with two Golden Globe Special Achievement Awards and an Emmy Award, among other honors. Several of his films are included in the National Film Registry by the Library of Congress. Disney was the first person to be nominated for Academy Awards in six different categories, a record he shares with Alfonso Cuaron and George Clooney (although Kenneth Branagh later surpassed all three with nominations in seven categories).

Born in Chicago in 1901, Disney developed an early interest in drawing. He took art classes as a boy and got a job as a commercial illustrator at the age of 18. He moved to California in the early 1920s and set up the Disney Brothers Studio with his brother Roy. With Ub Iwerks, he developed the character Mickey Mouse in 1928, his first highly popular success; he also provided the voice for his creation in the early years. As the studio grew, he became more adventurous, introducing synchronized sound, full-color three-strip Technicolor, feature-length cartoons and technical developments in cameras. The results, seen in features such as Snow White and the Seven Dwarfs (1937), Pinocchio, Fantasia (both 1940), Dumbo (1941), and Bambi (1942), furthered the development of animated film. New animated and live-action films followed after World War II, including the critically successful Cinderella (1950) and Mary Poppins (1964), the latter of which received five Academy Awards.

In the 1950s, Disney expanded into the amusement park industry, and in July 1955 he opened Disneyland in Anaheim, California. To fund the project he diversified into television programs, such as Walt Disney's Disneyland and The Mickey Mouse Club. He was also involved in planning the 1959 Moscow Fair, the 1960 Winter Olympics, and the 1964 New York World's Fair. In 1965, he began development of another theme park, Disney World, the heart of which was to be a new type of city, the "Experimental Prototype Community of Tomorrow" (EPCOT). Disney was a heavy smoker throughout his life and died of lung cancer in December 1966 before either the park or the EPCOT project were completed.

Disney was a shy, self-deprecating and insecure man in private but adopted a warm and outgoing public persona. He had high standards and high expectations of those with whom he worked. Although there have been accusations that he was racist or anti-Semitic, they have been contradicted by many who knew him. His reputation changed in the years after his death, from a purveyor of homely patriotic values to a representative of American imperialism. He nevertheless remains an important figure in the history of animation and in the cultural history of the United States, where he is considered a national cultural icon. His film work continues to be shown and adapted; his namesake studio and company maintain high standards in their production of popular entertainment, and the Disney theme parks have grown in size and number to attract visitors in several countries.
