Finding Harmony: A King's Vision Film Premiere Held at Windsor Castle

Historic Windsor Castle Premiere Marks New Documentary on King Charles III

Streaming globally on Prime Video from 6th February 2026

Windsor Castle made history on Wednesday evening as it hosted the world's first-ever film premiere at a Royal Residence. Their Majesties The King and Queen, accompanied by The Duchess of Edinburgh and The Duke and Duchess of Gloucester, gathered in the magnificent Waterloo Chamber for the Royal Premiere of Finding Harmony: A King's Vision, a landmark documentary chronicling His Majesty's lifelong environmental journey.

The documentary, produced by multi-award-winning Passion Planet in collaboration with The King's Foundation and narrated by Academy Award-winner Kate Winslet, will be available to watch globally from Friday 6th February 2026 exclusively on Prime Video in over 240 countries and territories worldwide.

A Lifetime in the Making

Finding Harmony: A King's Vision is described as a film about hope when the world needs it most. Filmed across four continents and spanning 75 years of remarkable archive footage, the documentary tells the story of how King Charles III has dedicated his life to finding environmental solutions—from his early environmentalism to the life-changing work of his charity, The King's Foundation.

The film reveals that His Majesty made a documentary about climate change as early as 1990—just years after scientists first went public about the issue. As Prince of Wales, he faced significant opposition when he pioneered organic farming and spoke up for biodiversity loss, deforestation, and climate change long before these became mainstream concerns.

Reflecting on viewing archive footage of himself speaking about pollution decades ago, The King says in the film: "Well, it was quite a long time ago and I remember being, well, profoundly concerned about all this. It seemed crazy to go on without thinking carefully about how we manage all this."

The Philosophy of Harmony

Central to the documentary is The King's philosophy of Harmony—the belief that we must see ourselves as part of nature, not apart from it. This philosophy, first articulated in his 2010 book Harmony: A New Way of Looking at the World (co-authored with Tony Juniper and Ian Skelly), encourages an interconnected, nature-first approach to tackling the world's climate challenges.

"It all boils down to the fact that we are actually nature ourselves, we are a part of it, not apart from it, which is really how things are being presented for so long," His Majesty explains. "Maybe, by the time I shuffle off this mortal coil, there might be a little more awareness… of the need to bring things back together again."

The film showcases how communities around the world are already putting Harmony into practice, from the forests of Guyana to sustainable communities in India, and closer to home through the work of The King's Foundation at Dumfries House and Highgrove.

Dumfries House: Harmony in Action

The documentary features extensively the work at Dumfries House in Ayrshire, Scotland—the headquarters of The King's Foundation and a flagship example of Harmony in practice. The 2,000-acre estate, which The King saved for the nation in 2007 through a personal loan, has become a catalyst for regeneration in an area once devastated by the decline of coal mining.

"When I discovered that this place was due to be sold and everything in it, I eventually took a somewhat risky decision to raise the money in a loan," The King recalls. "I felt it was critical to try and demonstrate how you could regenerate an entire area. How we could help raise aspirations and create new hope by bringing people together in a thoroughly integrated, collaborative way."

Since 1990, The King's Foundation has influenced the sustainable design of more than 175 communities worldwide, with over 350,000 homes influenced by its town planning resources and more than half a million lives positively impacted through its approach to sustainable urbanisation.

A Royal Premiere Like No Other

The premiere venue itself reflected the documentary's themes. The Waterloo Chamber—a principal State Room with a history of theatrical productions dating back to Queen Victoria—was transformed into a state-of-the-art cinema. The room was dressed in florals and foliage sourced from the Royal Gardens Nursery, all of which will be replanted on the estate after the event.

Guests followed a dress code of "Rewear, Repair or Recycle," fitting the sustainable theme. Members of the Royal Family and King's Foundation ambassadors wore handcrafted embroidered brooches created by graduates of the CHANEL & King's Foundation Metiers d'Art Embroidery Fellowship in partnership with Le19M.

Notable attendees included King's Foundation ambassadors Kate Winslet, Sir Rod Stewart, and Lady Penny Lancaster, alongside friends of the charity including Dame Judi Dench, Benedict Cumberbatch, and Stanley Tucci. A special "Harmony Highball" cocktail was created for the occasion, featuring Scotch Whisky, dried rosehip, roasted acorn liqueur, and spiced apple soda.

Kate Winslet: "A Film This Special"

Introducing the film to the assembled guests, Kate Winslet spoke of her pride in becoming an Ambassador for The King's Foundation and her even greater pride in providing the narration.

"Only a film this special, this important, could be given such an appropriate maiden voyage," she said. "I learnt so much about the philosophy of Harmony, and how simple it is both in concept and in practice, just through the experience of telling His Majesty's story within this extraordinary documentary."

Winslet described Harmony as "a beautiful theory" that invites people to see themselves as part of nature and to tackle climate challenges using an interconnected, nature-first approach. She added: "Filming may have taken place across a short six months, but Your Majesty, I know that for you, this documentary has been a lifetime in the making."

"We Are Destroying Our Means of Survival"

Despite decades of advocacy, The King remains candid about his concerns. When asked if he is worried about the state of the world, he responds simply: "Of course! That's been my main motivation for a long, long time."

Speaking about changes he has witnessed at Highgrove over 45 years, His Majesty reflects: "I used to hear cuckoos, which you never hear a single cuckoo now. And there used to be grasshoppers and, you know, the place used to hum. And that wonderful sound, you don't get much of that."

The King is direct about the challenges facing the planet: "People don't seem to understand it's not just climate that's the problem, it's also biodiversity loss... So, we're actually destroying our means of survival, all the time. To put that back together again is possible, but we should have been doing it long ago. We've got to do it as fast as we can now."

A Message of Hope

On the announcement of the documentary, His Majesty shared his hopes for its impact: "Nature is our sustainer. We are a part of Nature. Therefore what we do to her, we do to ourselves. But we have forgotten that we need to give back to Nature in return for what we take from her."

He continued: "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. 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."

Kristina Murrin CBE, Chief Executive of The King's Foundation, described the film as "a real labour of love" and said audiences will finally get "a better insight" into what The King's Foundation does as an organisation. She added: "The King is a very special person. He's incredibly practical and wants to get stuck in."

As for The King himself, he maintains a characteristically humble perspective on the endeavour: "It would be nice to try and see if we can get through to people, but who knows?"
