Though Mary Poppins has been a classic film for kids born as recently as this decade to watch, unbelievably, it has been a whopping 60 years since it first premiered in 1964.

The beloved musical, starring legends Julie Andrews and Dick van Dyke, both of whom are still working today, marked the milestone 60th anniversary of its release on August 27.

At the time, it earned $44 million, making it the highest-grossing film of the year, and received 13 Academy  Award nominations. Moreover, not only was it the Sound of Music actress’ film debut, when she was 29, but among the Oscar nominations was her nod for Best Actress, which she won.

Walt Disney had been trying to make Mary Poppins for decades, and in fact, he chose Andrews as his lead star back in 1962, however she was pregnant at the time; Mr. Disney, set on her being the iconic nanny, waited for her to give birth to start production.

“In retrospect, I could not have asked for a better introduction to film, in that it taught me so much in such a short period of time. The special effects and animation challenges alone were a steep learning curve, the likes of which I would never experience again,” she wrote in her second memoir, 2019’s Home Work, per the BBC.

Waiting for a star

Though Mr. Disney knew Andrews was his Mary Poppins by 1962, he told her he’d wait until she gave birth to her daughter Emma, shared with ex-husband Tony Walton, to start production. Her casting was announced as soon as she gave birth, on November 28, 1962.

Julie Andrews was passed over, in favor of Audrey Hepburn, for the role of Eliza Dolittle in My Fair Lady, which she originated on stage. This freed her to play the title role in Mary Poppins, for which she won the Academy Award for Best Actress; Hepburn was not even nominated.

When one door closes…

Before filming Mary Poppins, Andrews was famously passed over in favor of Audrey Hepburn to play Eliza Dolittle in My Fair Lady, a role she had first played in its theatrical production. Despite the setback, it allowed her to star in Mary Poppins, making for her first film and first Oscar win (Hepburn did not receive a nomination).

Forever Mary & Bert

The former co-stars have reunited several times throughout the years, however they had an extra special reunion in 2013, one year before the 50th anniversary of the film, for the premiere of Saving Mr. Banks, starring Tom Hanks and Emma Thompson, which tells the story of Mr. Disney’s 20-year quest to obtain the movie rights to Mary Poppins in the first place.
