LONDON — A new documentary highlighting King Charles III's decades-long commitment to environmental causes has generated buzz with the release of its trailer, offering viewers a glimpse into the monarch's vision for harmony between humanity and nature.
The film, titled Finding Harmony: A King's Vision, is set to premiere on Prime Video on February 6. Clocking in at 90 minutes, the documentary is narrated by Academy Award-winning actress Kate Winslet and draws on 75 years of archive footage filmed across four continents. According to producers, it promises a "sumptuous cinematic experience" designed to leave audiences "feeling uplifted and motivated to bring nature back into everything we do."
King Charles, who has long been a vocal advocate for environmental issues, uses the trailer to articulate his philosophy. "We are nature ourselves. We are a part of it, not apart from it," he says in one poignant moment. The documentary traces his journey from Prince of Wales, when he first championed causes like biodiversity loss, deforestation, and climate change—topics that were far from mainstream in the 1970s and 1980s.
Filmmakers collaborated with The King's Foundation, the monarch's charity dedicated to sustainable practices and community regeneration. The project, directed by Nicolas Brown and produced by Passion Planet in partnership with Amazon MGM Studios, also spotlights the foundation's impactful work. A newly released photograph of the King, taken during filming at Dumfries House in Scotland—the foundation's headquarters—captures him in a reflective pose against the estate's lush grounds.
In the trailer, the King emphasizes the urgency of reintegrating nature into human endeavors. "We must put nature back at the heart of the equation," he states, urging global action to ensure the planet can sustain its growing population. With a glance skyward, he adds a sobering note: "It's unlikely there's anywhere else." These words underscore the documentary's core message: fostering harmony as a pathway to planetary survival.
The release comes at a time when climate concerns dominate international discourse. The United Kingdom, for instance, is on track for its warmest year on record in 2025, according to the Met Office. Meanwhile, cities like Delhi grapple with air pollution described as its "biggest killer," and water shortages threaten evacuations in major urban areas worldwide. King Charles's film arrives amid these escalating challenges, positioning his personal advocacy within a broader global context.
Historically, the then-Prince Charles began speaking out on environmental matters as early as 1970, when he warned about pollution during a speech at the age of 21. Over the years, he established the Prince's Trust and promoted organic farming through his Highgrove estate. As king, his focus has shifted to institutional influence, including initiatives through The King's Foundation, which has restored historic sites while emphasizing eco-friendly architecture and education.
The documentary's production involved extensive archival material, chronicling not just the King's efforts but also the evolution of environmental science. It highlights how his early warnings about deforestation and biodiversity—issues now central to UN climate summits—were initially met with skepticism but have since gained widespread acceptance. Producers note that the film aims to inspire a new generation, particularly through Winslet's narration, which adds emotional depth to the narrative.
Kate Winslet, known for roles in films like Titanic and The Reader, brings her own environmental credentials to the project. She has publicly supported conservation efforts and sustainable living, making her a fitting voice for the King's message. In a statement accompanying the trailer, Winslet described the documentary as "a profound reminder of our interconnectedness with the natural world."
While the film celebrates the King's vision, it also touches on the criticisms he has faced over the years. Some have accused him of being ahead of his time to the point of eccentricity, particularly in the 1980s when he advocated for alternative medicine and holistic approaches alongside environmentalism. However, supporters point to his prescience; today, his calls for action align closely with reports from bodies like the Intergovernmental Panel on Climate Change (IPCC), which warn of irreversible damage if biodiversity isn't prioritized.
The trailer, released on January 1, 2026, has already sparked interest on social media, with environmental groups praising its timely release. Organizations like the World Wildlife Fund have echoed the King's sentiments, stating that "putting nature at the heart of decision-making is essential for a sustainable future." Meanwhile, skeptics in political circles question the role of monarchs in policy advocacy, though Buckingham Palace maintains that the King's work remains non-partisan and focused on charity.
Beyond the personal story, Finding Harmony delves into practical examples from The King's Foundation. Projects at Dumfries House, for instance, include regenerative agriculture programs that restore soil health and support local biodiversity. The estate, acquired by the foundation in 2007, serves as a model for blending heritage preservation with modern sustainability, attracting thousands of visitors annually for educational tours.
As the documentary approaches its February debut, it coincides with upcoming global events, such as the UN's biodiversity conference in 2026. King Charles, who attended the COP26 summit in Glasgow in 2021 as prince, has expressed hope that the film will encourage viewer participation in grassroots efforts. "Follow harmony," he implores in the trailer, a simple yet evocative call to action.
The broader implications of the King's environmental legacy extend to policy influence. In the UK, his advocacy has contributed to shifts like the 2021 Environment Act, which mandates biodiversity net gain in development projects. Internationally, his foundation partners with indigenous communities across the four continents featured in the film, amplifying voices often overlooked in climate discussions.
Looking ahead, the documentary's release on Prime Video ensures wide accessibility, potentially reaching millions. Producers anticipate it will not only honor the King's 75-year journey but also catalyze personal and collective change. As climate crises intensify—from record UK temperatures to global water scarcity—the film serves as a reminder that individual visions can shape planetary futures. For now, the trailer's message resonates: humanity's harmony with nature isn't optional—it's essential.
