Watch the trailer for Nicolas Brown’s upcoming film showcasing the King's environmental philosophy

The King’s Foundation and Prime Video have released the trailer for a landmark documentary on King Charles' lifelong effort to bring nature and humanity into harmony directed by Stern & Wild filmmaker Nicolas Brown.

Narrated by Kate Winslet, the 90-minute film FINDING HARMONY: A KING’S VISION charts the story of how the King, as Prince of Wales, pursued early environmentalism and spoke up for the science behind biodiversity loss, deforestation and climate change long before these issues became mainstream. It also shows the monarch’s philosophy in practice through the life-changing work of his charity, The King’s Foundation.

In addition to the Oscar-winning star, the Foundation’s work around sustainability, heritage skills and community building is championed by a growing number of high-profile celebrity ambassadors and supporters, many of whom appear in the film. The list includes David Beckham, Raymond Blanc, Naomi Campbell, Patrick Grant, Maro Itoje, Sienna Miller, Rod Stewart & Penny Lancaster, Meryl Streep and Stanley Tucci.

The King has described his hope that the film will “encourage a new audience to learn about the philosophy of Harmony” and inspire the same “sense of determination” that he feels to protect our planet and create a more sustainable future for the next generation.

Filmed across four continents, and spanning 75 years of remarkable archive footage, the film aims to offer a positive vision for the future and promises to be a visual feast. It is produced by Passion Planet in collaboration with The King’s Foundation for Prime Video.

It will be released on Friday 6 February 2026 on the Amazon streaming platform.
