Hollywood has a funny way of freezing people in time. For most of the world, the seven children from the 1965 cinematic masterpiece are still running around the Salzburg hills in playclothes made from old curtains. They are eternal. But the reality is that the The Sound of Music stars lived lives that were often far more complicated, and occasionally more tragic, than the "Do-Re-Mi" montage suggests.
It’s been over sixty years.
Think about that. The movie wasn't just a hit; it was a cultural shift that saved 20th Century Fox from bankruptcy after the Cleopatra disaster. Yet, for the actors who played the von Trapp children, that success was a double-edged sword. They weren't just actors; they became a collective identity. Even today, fans track their every move. But if you look past the dirndls and the high notes, you find a story of typecasting, career pivots, and a bond that actually outlasted the biological von Trapp family's own unity.
The Lies the Movie Told You (And Why the Stars Lived Them)
Let's get one thing straight: the movie isn't a documentary. Not even close. The real Maria von Trapp was a bit of a powerhouse, and Georg von Trapp was actually quite warm, not the cold whistle-blower Christopher Plummer portrayed. The The Sound of Music stars had to navigate this weird middle ground where they were playing "real" people who were still alive and often vocal about their dissatisfaction with the script.
Charmian Carr, who played Liesl, was actually 21 when she was "sixteen going on seventeen." She wasn't a teenager. She was a woman who had to hide her age to fit the role. That’s a strange way to start a career. She eventually left acting altogether to run an interior design business in California, famously counting Michael Jackson as one of her clients. She wrote books about her experience, Forever Liesl and Letters to Liesl, because she realized she could never truly escape the shadow of that gazebo.

Then there’s the age gap. Nicholas Hammond, who played Friedrich, grew about six inches during filming. If you watch the movie closely, he’s wearing lifts in some scenes and standing in holes in others to keep the height progression of the siblings looking "correct." It’s these tiny, human details that the The Sound of Music stars remember—the itchy wool costumes, the smell of the Austrian rain, and the fact that they all got sick from the lemonade provided on set.
Where the Career Paths Diverged
Some stayed. Some ran.
Nicholas Hammond actually had a massive career after Salzburg. You might remember him as the first live-action Peter Parker in The Amazing Spider-Man TV series in the late 70s. He moved to Australia, became a writer and director, and even had a meta-moment appearing in Quentin Tarantino’s Once Upon a Time in Hollywood. He's one of the few who successfully transitioned from "child star" to "working actor" without the industry chewing him up.
Heather Menzies-Urich (Louisa) had a tougher time with the transition. She famously posed for Playboy in the 70s to break her "innocent" image, a move that shocked the more conservative fans of the film. It's a classic Hollywood story: the desperate attempt to prove you've grown up. She later married actor Robert Urich and devoted much of her life to cancer research after his diagnosis, showing a depth of character that far surpassed her scripted lines as a mischievous prankster.

The smaller you were, the harder it hit.
- Duane Chase (Kurt): He basically looked at Hollywood and said, "No thanks." He went into forestry and geophysics. He’s a guy with a PhD now, living a quiet life in Washington state.
- Angela Cartwright (Brigitta): She was already a pro from Make Room for Daddy and later Lost in Space. She became a photographer and artist.
- Debbie Turner (Marta): She took the "normal" route, focusing on family and a floral design business.
- Kym Karath (Gretl): The youngest. She almost drowned during the boat scene because she couldn't swim and Julie Andrews was supposed to catch her but fell the other way.
Kym's story is particularly harrowing because that boat flip wasn't "movie magic" for a five-year-old. It was terrifying. It took her years to get comfortable in water again. When we talk about The Sound of Music stars, we often forget they were just kids being tossed into lakes for our entertainment.
The Christopher Plummer Factor
Honestly, Christopher Plummer hated the movie for a long time. He famously referred to it as "S&M" or "The Sound of Mucus." He felt it was too sentimental, too "gooey." For the child actors, this was intimidating. Imagine being ten years old and working with a Shakespearean titan who clearly doesn't want to be there.
But a funny thing happened over the decades. Plummer softened. He realized that for millions of people, this was the most important film of their lives. Before his passing in 2021, he had reconciled with the cast. The The Sound of Music stars became his friends. They were the only ones who truly understood what it was like to be trapped inside a phenomenon. When the cast reunited on Oprah in 2010, it was the first time in 45 years they had all been in the same room with Julie Andrews and Plummer. The chemistry wasn't faked; it was forged in the fire of 1960s fame.

The staying power of these actors is weirdly unprecedented. Usually, child stars from the 60s are footnotes. But The Sound of Music stars are different because the film represents a version of "family" that people are desperate to believe in.
We’ve seen the "real" von Trapp family history—the fact that they struggled financially in America, the fact that Maria could be quite a disciplinarian. But the actors provided a secondary, "chosen" family. They actually like each other. They call each other. They show up for each other’s weddings and funerals. In a world of fake PR stunts, their genuine lifelong bond is the most "human" thing about the whole franchise.
Insights for the Modern Fan
If you're looking to connect with the legacy of these performers, don't just re-watch the movie. Look at their later contributions.
- Check out the books: Charmian Carr's memoirs offer a shockingly blunt look at the filming process. It’s not all sunshine and edelweiss.
- Support their causes: Many of the surviving cast members are heavily involved in the Urich Foundation for cancer research or various arts education programs.
- Visit the Salzburg sites with context: When you see the Mirabell Gardens, remember that the "kids" were often exhausted, dealing with growth spurts, and trying to navigate the massive expectations of a director like Robert Wise.
The real takeaway here is that being one of the The Sound of Music stars wasn't a golden ticket to an easy life. It was a unique, sometimes burdensome, identity that each of them had to navigate in their own way. Some found peace in science, others in art, and some in the very industry that tried to keep them "sixteen going on seventeen" forever.
To truly honor their work, we have to see them as the versatile professionals they became, rather than the children we want them to remain. They survived the hills, the Nazis (onscreen), and the even more dangerous landscape of child stardom. That’s the real performance worth applauding.
Next Steps for Enthusiasts:
Search for the 2010 Oprah reunion special to see the cast's final full gathering. It provides a raw, unscripted look at their dynamics. Additionally, research the "Von Trapp Children" (the actual great-grandchildren of Georg) who continue the musical legacy today under the name The von Trapps to see how the musicality has evolved through generations.
