The King said he had been "reduced to tears" by his wife's documentary on domestic abuse as he welcomed the stars of Gladiator II to Buckingham Palace ahead of its glittering world premiere on Wednesday afternoon.
Actor Damian Lewis who is currently starring as Henry VIII in Wolf Hall told Charles that he watched the Queen's recent television documentary and how moved he had been by it. "It's very moving, isn't it?" His Majesty said. "I think BAFTA are interested in it." He added: "Will you please give your fellow actors my regards. They are just brilliant in it."
The King also spoke to two of the makers of the Queen’s programme, Naveed Chowdhary-Flatt and Kerene Barefield, and told them he had been "reduced to tears" when he watched a preview of it in Scotland. He added: "I really am very proud."
Charles was joined by the Queen, the Duke of Edinburgh and the Duke and Duchess of Gloucester at the reception, but Camilla did not stay for the whole engagement with her diary adjusted this week to aid her recovery from a chest infection.
The event at the King's historic royal residence also marked the centenary of the Film and TV Charity, of which Charles has become patron, following in the footsteps of his late mother Elizabeth II who held the role since 1952.
As well as meeting some of the star-studded cast at the palace, the royals viewed costumes and props from films such as Titanic and Master And Commander: The Far Side Of The World, as well as the late Dame Maggie Smith's costume from the 1982 film Evil Under The Sun.
On the eve of his 76th birthday, the King will later make a solo outing to the glitzy global premiere of the highly anticipated Gladiator sequel at the Odeon Luxe in London's Leicester Square after Camilla pulled out of attending the red carpet affair
