Eight key details shape the story of Charmian Carr, from birth to the rare disease that took her life.

What did Charmian Carr pass away from?

Charmian Carr died on September 17, 2016, at the age of 73, from complications of a rare form of dementia known as progressive supranuclear palsy (BBC News). Her family confirmed the diagnosis and death, which occurred at a hospital in Woodland Hills, California (The Hollywood Reporter).

Progressive supranuclear palsy explained

• Progressive supranuclear palsy (PSP) is a neurodegenerative disorder that affects movement, balance, and eye control (Wikipedia).
• PSP is often misdiagnosed as Parkinson’s disease because of similar symptoms.
• The disease leads to progressive dementia and loss of motor function.

The implication: Carr’s final years were marked by a slow cognitive and physical decline, but her family chose to disclose the specific diagnosis, helping raise awareness of PSP.

How old was Charmian Carr when she played Liesl?

Charmian Carr was 21 years old when she was cast as 16-year-old Liesl von Trapp in 1964 (Wikipedia). Filming took place that year, and the movie premiered in 1965.

Charmian Carr age during filming

• Born December 27, 1942; filming in summer 1964 made her exactly 21.
• The character Liesl is portrayed as 16 in the film.
• This age gap of 5 years was common for Hollywood casting of teenage roles at the time.

Liesl von Trapp character age vs actress age

The contrast in ages across the young cast reveals a notable gap for Carr’s role.

The pattern: Carr was the oldest of the von Trapp children actors, yet she convincingly played a teenager, aided by her youthful appearance.

Did Charmian Carr do her own singing in The Sound of Music?

Yes, Charmian Carr performed her own singing in The Sound of Music. Her voice is heard in songs including “Sixteen Going on Seventeen” and the reprise (Wikipedia). No dubbing was used for her character.

Singing voice in the film

• Carr had no formal vocal training before the film but learned the songs during rehearsals.
• Director Robert Wise chose to use her natural voice rather than a professional dubber.

Who really sang for Liesl?

Unlike some other cast members with singing backgrounds, Carr’s voice is entirely her own. Julie Andrews, who played Maria, also performed her own singing. This contrasts with some later musical films where actors were dubbed.

The takeaway: Carr’s singing remains one of the most nostalgic elements of the film, and she often recalled the experience fondly in interviews.

Did Christopher Plummer have a relationship with Charmian Carr?

No, Christopher Plummer and Charmian Carr did not have a romantic relationship. They maintained a friendly professional rapport on set, and Carr’s autobiography Forever Liesl discusses her youthful crush on Plummer, who was 13 years her senior (Wikipedia). Plummer, who died in 2021, publicly praised Carr’s performance.

On-screen romance vs reality

The musical’s “Sixteen Going on Seventeen” scene suggests a budding romance between Liesl and Rolf, but off-screen, Plummer was already married and maintained a professional boundary.

Charmian Carr’s autobiography Forever Liesl

In her 2000 memoir Forever Liesl: My Sound of Music Story, Carr wrote candidly about the production, including her observations of Plummer and Julie Andrews. She described the set as a “wonderful second family” (Google Books). The book provides a behind-the-scenes look at the film’s making and its lasting impact.

The catch: Although rumors of a real-life romance circulated for decades, Carr’s own words in her memoir debunk them completely.

What was Charmian Carr’s life like after The Sound of Music?

After The Sound of Music, Charmian Carr retired from acting to raise her children and later built a successful interior design business (BBC News). She owned the firm Charmian Carr Designs in Encino, California (Wikipedia).
