King Charles is revisiting some comments he made 56 years ago in his new documentary, which were considered unheard of at the time.
A new trailer for Finding Harmony: A King’s Vision showed the royal watching one of his first-ever public speeches, where he spoke about his concerns for the environment.
“We are faced at the moment with the horrifying effects of pollution in all of its cancerous forms,” he began in his 1970 speech.
It then cut to the King, who was smiling as he watched his younger self.
“There is the growing menace of oil pollution at sea,” he continued in his public address. “There is chemical pollution discharged into rivers from factories and chemical plants, which clogs up the rivers with toxic substances and adds to the filth in the seas.”
Reflecting on it, Charles said it was a long time ago.
“And I — I remember being, well, profoundly, you know, concerned about all this,” he said in the trailer. “It seemed crazy to go on without thinking carefully about how we manage all this.”
Prince Harry’s shock cameo
The documentary is a rare TV project for King Charles, and it premiered at Windsor Castle on January 2.
In an unexpected surprise, Prince Harry has even made a fleeting appearance in the documentary.
Despite their estrangement, Harry reportedly makes an unexpected appearance in the form of archival footage.
According to Hello!, one sweet scene shows Charles fishing with Harry when he was a child, while Prince William also appears in two scenes as a child.
Princess Charlotte and Prince Louis, two of William’s children, are also said to feature in the documentary as does the late Queen Elizabeth.
A screening with A-listers
The documentary was screened for the first time at Windsor Castle, with A-list stars including Judi Dench and Benedict Cumberbatch attending.
It was a historic occasion, marking the first time a British royal residence has ever been used to host a film premiere.
Kate Winslet has narrated King Charles’ documentary, which will be released by Prime Video and is adapted from the monarch’s book, Harmony: A New Way of Looking at Our World.
Charles has long been passionate about climate change and wants to urge others to “protect and prioritise our planet” with the new documentary.
Charles has become the latest royal to appear on a streaming service, after Prince William appeared in Eugene Levy’s Apple TV+ series, The Reluctant Traveler, and Prince Harry and Meghan Markle starred in their own Netflix series.
“Nature is our sustainer—we are a part of nature,” Charles said of his exciting new project.
“Therefore, what we do to her, we do to ourselves. For much of my life, I have sought to promote and encourage ways we can work with, rather than against, nature. In other words, to restore balance to our planet, which is under such stress.
He said he hoped that the film demonstrates the “remarkable work being done around the world”, and the work of his foundation.
“Never has it been more important for the world to make a concerted effort to protect and prioritise our planet, and to restore our relationship with it,” he continued.
“It is therefore my fondest hope that this film may encourage a new audience to learn about the philosophy of Harmony – and perhaps inspire the same sense of determination it has given me to help build a more sustainable future.”
What is King Charles’ documentary about?
The documentary will highlight how the royal’s foundation has embraced the origins, evolution, and scientific foundations of his “Harmony” philosophy.
It will also explore its impact globally, highlighting examples of food production, urbanism, community regeneration, sustainable textiles, and traditional skills.
“Remarkably few people around the world know the full depth of The King’s lifelong battle to bring nature and humanity into harmony,” the Finding Harmony: A King’s Vision director, Nicolas Brown, said.
“Even today, His Majesty’s work with The King’s Foundation is transforming the world in so many inspiring ways.
“This is a story of hope and resilience.
“People who watch this film will leave feeling uplifted and motivated. The King’s philosophy offers something for everyone. Mostly, he shows us the power of resilience – and how following your intuition can transform the world.”
When does King Charles’ documentary air?
Finding Harmony: A King’s Vision will be released on February 6, 2026, exclusively on Prime Video.
It will be launched in 240 countries and territories and is being produced by Passion Planet, in collaboration with The King’s Foundation for Amazon MGM Studios.
