“Mary Poppins” first came out on August 27, 1964, at its world premiere in Los Angeles, California, and then rolled out more widely in the following weeks in other U.S. cities and countries.

Original release date

  • The film’s premiere was held at Grauman’s Chinese Theatre in Los Angeles on August 27, 1964, which is the date most often cited as when Mary Poppins “came out.”
  • It later opened in New York City on September 24, 1964, with further releases in the U.K. and other markets through late 1964 and early 1965.

Why that date matters

  • That August 27, 1964 premiere marked the start of the movie’s huge box-office run, during which it became the highest‑grossing film in the United States for 1964.
  • The success of Mary Poppins on and after that date helped cement Disney’s reputation for blending live action, music, and animation in a single feature film.
