"Mary Poppins" scored five Oscars, including best actress for its star Julie Andrews. It was her first feature film and won her a Golden Globe and a Grammy, too.
Her hair in the movie was "practically perfect in every way," but did you know it was a wig? She wore a dark wig to cover her blonde hair to play the super nanny.
At the start of the film, before Mary Poppins appears at 17 Cherry Lane, a scene shows dozens of nannies applying for the job. What you might not know is that many of them were actually stunt men dressed as women to deal with the gust of wind that blew them away.
Actor David Tomlinson played Mr. Banks and also voiced the parrot head on Mary Poppins' umbrella, but he wasn't the only one doing double duty.
Dick Van Dyke played the beloved chimney sweep, Bert, but was also cast as Mr. Dawes, the president of the bank. At the time, makeup transformed him into the elderly man.
In the credits Mr. Dawes was played by "Navckid Keyd," which is an anagram for Dick Van Dyke.
Van Dyke, now 93, appears in the new movie too.
"Mary Poppins Returns" is out in theaters Wednesday. The movie is a sequel to the original, featuring Emily Mortimer as the grown-up Jane Banks and Ben Whishaw as an older Michael Banks. It stars Emily Blunt and Lin-Manuel Miranda.
