The film, Finding Harmony: A King’s Vision, explores the monarch’s decades of advocacy for sustainability and nature, alongside the work of The King’s Foundation. Narrated by Kate Winslet, the documentary premiered on Amazon Prime Video on Friday, February 6, and blends archive footage with present-day reflections from the King himself.
The remark that refused to fade
The documentary highlights how Charles, then Prince of Wales, struggled in the 1980s to have his environmental concerns taken seriously. While speaking to the press in a 1986 television interview about organic farming, he made an offhand comment that quickly became a source of mockery.
“I just come and talk to the plants, really. Very important to talk to them, they respond,” he said at the time.

As Kate Winslet explains in the film, that single sentence ended up haunting him for years. Media coverage following the interview was harsh, with newspapers portraying him as eccentric and out of touch. One headline shown in the documentary dismissed him as “completely off his trolley”.
