A number of stars joined King Charles to see the first film to premiere in a royal residence. Benedict Cumberbatch, Sir Kenneth Branagh, Dame Judi Dench and Stanley Tucci were among the 222 guests at Windsor Castle on Wednesday, 28 January, to view a new Prime Video documentary about Charles’s environmentalism. Musicians Sir Rod Stewart and Jools Holland plus Oscar-winner Kate Winslet – who narrates the documentary, Finding Harmony: A King’s Vision – were also at the screening. Charles states he “wasn’t going to be diverted” from his environmental campaigning, despite the criticism he faced over the decades. Finding Harmony: A King’s Vision will be released on February 6 on Prime Video in more than 240 countries and territories worldwide.
