EXCLUSIVE: The Royal Rules King Charles Broke for the Sake of His New Nature Film

A centuries-old castle rule was quietly set aside for the occasion.

King Charles just shattered one of Windsor Castle’s stuffiest rules.

The monarch staged an unprecedented film premiere inside the 1,000-room royal residence – even waiving a decades-old photography ban – to roll out his new environmental documentary Finding Harmony: A King’s Vision.

The 90-minute documentary, which launched on Amazon Prime Video on February 6, explores Charles’ lifelong commitment to environmental stewardship and sustainable living.

Ahead of its release, the King hosted a private screening in the historic Waterloo Chamber at Windsor Castle – the first time a commercial film premiere has ever been staged inside a royal home.

Ordinarily, the castle’s regulations state: “Photography and filming, including wearable devices, are not permitted inside the State Apartments or St George’s Chapel.”

But for this occasion, that rule was temporarily relaxed.
