Mary Poppins (musical)
Mary Poppins is a musical with music and lyrics by Richard M. Sherman and Robert B. Sherman (the Sherman Brothers) and additional music and lyrics by George Stiles and Anthony Drewe, and a script by Julian Fellowes. The musical is based on the similarly titled Mary Poppins children's books by P. L. Travers and the 1964 Disney film, and is a fusion of various elements from the two, including songs from the film.
Walt Disney
In 1964, Disney produced "Mary Poppins", based on the book series by P. L. Travers; he had been trying to acquire the rights to the story since the 1940s. It became the most successful Disney film of the 1960s, although Travers disliked the film intensely and regretted having sold the rights. The same year he also became involved in plans to expand the California Institute of the Arts (colloquially called CalArts), and had an architect draw up blueprints for a new building.
