King Charles hosted several A-list stars at Windsor Castle on Wednesday, as they showed up to attend the premiere of his Harmony documentary, which will release on Amazon Prime on 6 February 2026.
Among the stars seen attending the premiere were Kate Winslet, who also narrates the documentary, Dame Judi Dench, Stanley Tucci, Benedict Cumberbatch, Sir Kenneth Branagh, Alan Titchmarsh, Rod Stewart and Penny Lancaster.
Charles was also joined by some royal guests, with his wife, Queen Camilla, and the Duke and Duchess of Edinburgh heading out to support the monarch.
Harmony is based on the monarch's 2010 book, Harmony: A New Way of Looking at Our World.
The 336-page book examined the King's interest in environmentalism, and "looks at different aspects of our modern world to demonstrate how many of the challenges seen in areas as diverse as architecture, farming and medicine can be traced to how we have abandoned a classical sense of balance and proportion".
