Julie Andrews — daredevil?

In a new interview on “The Late Show With Stephen Colbert,” the beloved actress reveals the movie magic required to make her 1964 classic, “Mary Poppins,” including performing her own “stunts” – with the help of wires and harnesses, of course. The high-flying action was saved “[until] the last moment” of filming, because, as Andrews jokes, “If there’d been an accident or something, then I was dispensable after that!”

But the 81-year-old reveals there in fact was an on-set mishap. In one instance, while filming a scene where she flies with her umbrella, she didn’t exactly take flight.

“I thought I felt the wire drop around six inches, so I thought, Oh gosh, to have an accident at the end of the show like this,” she tells Colbert. “I was nervous, and very tired.”

Andrews continues, “So I called down and I said, ‘Excuse me, when you do let me down, could you let me down really gently, because I felt myself slip and I just don’t feel too safe up here.'” Of course, that really gentle landing didn’t go quite as planned: “I plummeted to the stage.”

Thankfully, the incident ended much less painfully than it could have. “There was an awful silence for a minute,” Andrews recalls. “I did let fly with a few Anglo-Saxon four-letter words, I do have to say!”
