Julie Andrews has fans talking after a rare video appearance sparked concern over her health — and then appeared to disappear from the internet.

The beloved Sound of Music and Mary Poppins star, 90, appeared in a pre-taped YouTube message for the World Parkinson Congress in late May. The video was posted by the World Parkinson Coalition to welcome attendees to the event.

But the emotional message quickly drew attention for more than just its powerful words.

In the clip, Andrews spoke about the devastating impact of Parkinson’s disease and urged viewers to keep fighting for a cure.

“Your participation is invaluable as we seek to find a cure to this terrible disease,” Andrews said. “I know well how devastating it can be.”

The remark immediately set off speculation among some viewers, who wondered whether the Hollywood legend was speaking from personal experience.

There has been no public confirmation that Andrews has been diagnosed with Parkinson’s disease. Still, the video fueled concern because of her age, her emotional delivery, and the fact that she has been seen on camera only rarely in recent years.

The clip also came as several major stars have spoken openly about their own experiences with Parkinson’s, including Neil Diamond, Michael J. Fox, and Alan Alda.

In her message, Andrews encouraged people to become a source of hope in the fight against the disease.

“May we all become a beacon of light to stop it in its tracks,” the Mary Poppins icon said in the video. “Count me in.”

Days later, however, the recording appeared to have been taken down, adding to the questions surrounding the appearance.

The deleted video also brought an uglier side of the internet into view. According to an insider, Andrews was subjected to cruel comments about her appearance after the clip was posted.

“Julie has given generations joy through her work, and people were horrified to see her subjected to such ugly personal attacks over simply appearing on camera at 90 years old,” the source said.

The insider added that “the trolling crossed a line very quickly.”

Andrews has long been one of Hollywood’s most cherished performers. Her roles in The Sound of Music and Mary Poppins made her a household name, while her decades-long career helped define a golden era of family entertainment.

For many fans, seeing her lend her voice to a Parkinson’s awareness event was moving. But the sudden removal of the clip, combined with the speculation it triggered, left many wondering why the message vanished.

For now, Andrews has not publicly addressed the video, the online reaction, or the health rumors.
