King Charles hosts ‘first’ at Windsor Castle
Wednesday night saw King Charles, 77, host the first-ever movie premiere to take place at Windsor Castle.
Windsor Castle played host to the premiere of a new documentary movie about King Charles’ environmental work titled Finding Harmony: A King’s Vision.
It premiered at the castle on Wednesday night and will be available to watch on Amazon Prime on February 6.
In a video posted on the official royal family Instagram account, fans were given a better look at last night’s historic premiere.
With Coldplay’s A Sky Full of Stars playing in the background, the video featured clips of the king meeting the likes of Benedict Cumberbatch, Judi Dench, and Stanley Tucci during the premiere. Rod Stewart and Penny Lancaster were also shown to be in attendance, as were Kate Winslet, Jools Holland, and Kenneth Branagh.

‘A magical evening’
The king wasn’t the only royal in attendance.
He was joined by his wife, Queen Camilla, as well as his sister-in-law, Sophie, Duchess of Edinburgh. The Duke and Duchess of Gloucester were also in attendance.
However, the Prince and Princess of Wales were absent from the premiere, as were Prince Edward and Princess Anne.
It’s strange that Prince William and Princess Catherine didn’t attend this event.
“A magical evening at Windsor Castle,” the caption of the Instagram video read.
“The King and Queen attended the premiere of ‘Finding Harmony: A King’s Vision‘.
“Available to watch on Prime Video from Friday, 6th February 2026, the film outlines His Majesty’s philosophy of ‘Harmony’. Exemplified through the work of @kingsfoundation, Harmony encourages us to see ourselves ‘as part of nature, not apart from nature.'”

Fans gush over King Charles’ movie premiere
Some of the people who had been in attendance at the film premiere took to the comment section to gush over the evening.
“Incredible evening and loved the film!” one gushed in the comments.
“Thank you so much for a lovely evening! The film is incredible and shows you the sheer amount of willpower, work and positivity that HRH the King, The King’s Foundation, and all the organisations involved actually do!” another wrote.

“Great film,” Jools Holland said.
Others were left questioning why William and Catherine weren’t at the event. One person said: “It’s strange that Prince William and Princess Catherine didn’t attend this event.”
Another claimed: “I’ve noticed you never invite Prince William and Princess Catherine whenever you host your celebrity receptions.”
Royal Insider contacted reps for Kensington Palace for comment.
Kate Winslet’s sweet moment with King Charles
A string of stars were also in attendance at the glamorous evening, including none other than Kate Winslet.
A clip of the beloved Titanic actor has been doing the rounds on social media, as it captured a sweet moment where Kate praised King Charles.
The footage shows King Charles making a beeline to Kate with his hand outstretched.
Kate Winslet then scrunched up her face in a sweet smile and offered a curtsy whilst gripping onto King Charles’s hand.
Unfortunately Charles’s words of greeting were inaudible, but Kate replied in a gleeful manner, beaming as she said to the king: “It was wonderful, I loved it. I loved it.
“Are you pleased?”
In the video, Charles faces away from the camera, making it difficult to understand his reply, but whatever he said it seemed to spark a giggle from Kate who burst out in laughter.
Observers flocked to the comment section where they shared their own praise.
“I think Kate and the King already have a friendship. That is a genuine meeting there,” gushed one.
“Love her so much,” said another.
“Her reaction says it all,” praised a third.
Awww!

Kate Winslet’s work with King Charles
The unlikely duo are known to share a friendship.
They have even collaborated together in recent months.
In a formal statement released in early 2025, Winslet celebrated her new role as ambassador for The King’s Foundation.
“One of my passions is exploring ways we can protect and promote the natural world – something I have in common with His Majesty!” she said.
“I am therefore thrilled to put this passion into practice by working with The King’s Foundation. I look forward to supporting the charity’s life-changing work to build sustainable communities and transform lives into the future.”
