Julie Andrews: 'The Sound of Music' is "Like an Old Friend"

Can you believe it’s been 50 years since The Sound of Music hit theaters? Julie Andrews sure can’t!

“Let’s just say, I think it’s a joke,” the 79-year-old star quipped in a new interview. “I think someone pulled a fast one on me — I lost 20 years somewhere, surely it’s only been 30 years!”

Though Julie admitted she doesn’t go out of her way to rewatch the classic film “as a rule,” she confessed she’ll sometimes “bump into it, and it’s like an old friend.”

“The memories [from filming] are great, though — the pleasure of making it and the friendship with the children and Christopher [Plummer] continues, and I see him a lot, and the children are always in some contact one way or another,” she lovingly said of her former costars.

As for why the movie — which won the Best Picture Oscar in 1965 — continues to enthrall generation after generation 50 years later, Julie said the answer is “obvious”!

“Every 70 years, there’s a new generation, but the film has to be good to last that long anyway!” she said on ‘Good Morning America.’ “It’s got children and nuns… and beautiful scenery — somewhere in there is the secret.”
