When the Prince and Princess of Wales unveiled their heartwarming new video, in which Kate Middleton revealed that she has completed her chemotherapy treatment, it was unsurprising to see that it was shot by Will Warr.

The videographer has long been trusted by the royal couple, and has often worked with them on intimate behind-the-scenes projects, including footage which showed the family getting ready for the Coronation.

The London-based filmmaker, of Brixton, London, is married to Sarah Warr and is a father-of-one to their baby Frederick Skye Grayling Warr, who is turning two later this month.

Will's current focus appears to be creating content for foodie channel Topjaw, which asks celebrities and culinary VIPs about their favourite restaurants. Recently, he and host Jesse Burgess worked with A-listers including Jamie Oliver, Ed Sheeran and Stanley Tucci.

He also does weddings, and has worked across projects with several brands, such as Red Bull, Candy Kittens, Brooklyn Brewery, Uber Eats, Miele, Bloom & Wild, Diageo, Puma and Holland Cooper.

The videographer has in past said it was 'wonderful' an 'honour' and a 'privilege' to work with the Princess, with whom he has worked on a number of initiatives. 

In December, Will was on hand when she was 'highlighting the important work of volunteers at the UK's Baby Banks.

And the month prior, he had joined the Waleses in Singapore to film content for the Earthshot Prize. 

Will has also worked on shooting footage for the Coronation, as well as the Prince and Princess of Waleses' ten-year anniversary back in 2022. 

His most recent success has come from Topjaw, which he and Jesse only launched last year. 

While they have focused on shortform endeavours, Will hopes they will expand the project.

'I love long-form, shooting landscape, cinematic and epic,' he told the Financial Times. 'The dream is one day to have our own Netflix show.' 

The slick advertising filmmaker was also behind the Tesco Food Love Stories ads.

According to his website, after training as a designer he set out on a 'one-man mission to create beautiful, engaging visual content' - and five years on has 'a portfolio of world-leading clients with whom he creates story-led branded content, corporate films and commercials'.

From creative design and artistic direction through to post-production, including animation and sound design, Will and his team 'build close working relationships with clients from initial concept through to high value finished product'. 

Will, who now boasts 44,600 followers on Instagram and counting, is followed by Made in Chelsea's Jamie Laing - having produced content for his brand Candy Kittens and his wedding - as well as Matt Porteous, the award-winning Royal Family photographer who captured images of the family used for their most recent official Christmas card.

In his latest project for the Waleses, Will captured the pair's three children playing around in nature, laughing up a storm during card games and larking around with a camera - as Kate Middleton, 42, revealed that her chemotherapy treatment has come to an end.

Sharing the video on his Instagram today, he wrote: 'It’s always an honour to produce films for @princeandprincessofwales, but this one was particularly poignant. Thank you to The Princess of Wales for trusting me to create this.'

The royal offered an intimate glimpse into her family life as footage showed her and Prince William's kids spending quality time in Norfolk with their parents in the moving clip, shot last month.

'As the summer comes to an end, I cannot tell you what a relief it is to have finally completed my chemotherapy treatment,' she said.

'The last nine months have been incredibly tough for us as a family. Life as you know it can change in an instant and we have had to find a way to navigate the stormy waters and road unknown.'

Prince George, 11, Princess Charlotte, nine, and Prince Louis, six, showed their playful natures in the video as they took part in several fun activities with their family.

In one instance, William and Kate's eldest son grinned as he carried a cricket bat while hiking through the woods with his parents and siblings.

Footage also showed the three children donning summery ensembles as they joined their family on nature walks, in the video.

In another snap, a laughing Louis is pushed on a swing by his mother, as both bask in the sweet moment.

Experimenting with the camera, another shot also shows George starting in the lens as he asks 'is this filming?' while sat on a picnic blanket with his mother.

Louis then enters the frame to say: 'Hello!' while Charlotte also laughs and joins in.

The energetic trio also climbed around on wooden logs, shared cuddles with their family, and played card games with their grandparents, Michael and Carole Middleton.

The candid video also shows Louis ambitiously climbing up a tree as his mother carefully watches, and William removing a bug from Charlotte's hair.

The whole family, in another heartwarming shot, races through the sea on the beach at one point. 

The setting of the footage is deeply symbolic, drawing on the strength Kate has drawn from her family and loved ones and from spending time on the things which bring her joy, particularly the sanctuary she has found in the natural world.

It also features her parents, Michael and Carole Middleton, who have been an unwavering source of support.

The princess' personal message also featured footage of William and Kate laying entwined on a blanket, hugging their children – and kissing.

'The cancer journey is complex, scary and unpredictable for everyone, especially those closest to you,' Kate said.

'With humility, it also brings you face to face with your own vulnerabilities in a way you have never considered before, and with that, a new perspective on everything.

'This time has above all reminded William and me to reflect and be grateful for the simple yet important things in life, which so many of us often take for granted. Of simply loving and being loved. '

Referring to her plans for the coming months, Kate continued: 'Doing what I can to stay cancer free is now my focus.

'Although I have finished chemotherapy, my path to healing and full recovery is long and I must continue to take each day as it comes.

'I am however looking forward to being back at work and undertaking a few more public engagements in the coming months when I can.

'Despite all that has gone before, I enter this new phase of recovery with a renewed sense of hope and appreciation of life.

'William and I are so grateful for the support we have received and have drawn great strength from all those who are helping us at this time. Everyone's kindness, empathy and compassion has been truly humbling.'

And she ends it with a deeply moving and emotional message to fellow cancer patients and their families, saying: 'To all those who are continuing their own cancer journey – I remain with you, side by side, hand in hand. Out of darkness, can come light, so let that light shine bright.' 

Kate, when she first shared news of her health struggles earlier this year, she admitted it had taken her and her husband 'time to explain everything to George, Charlotte and Louis in a way that is appropriate for them, and to reassure them that she is going to be ok'.

'As I have said to them; I am well and getting stronger every day by focusing on the things that will help me heal; in my mind, body and spirits,' she explained, in March.

'Having William by my side is a great source of comfort and reassurance too. As is the love, support and kindness that has been shown by so many of you. It means so much to us both.'

Palace source emphasised that while the princess is looking forward to undertaking a 'handful' of public engagements over the coming months, her focus is on being 'cancer free' and her journey to full recovery 'is long'.

Her programme of engagements will be 'light' but is likely, as previously revealed by the Daily Mail, to including Remembrance Sunday at the Cenotaph and other events around it.

She will not accompany Prince William to his Earthshot Prize awards in Cape Town in November, emphasising she wanted to remain in the UK to support her young family for whom the year has been difficult too.

She has already started to work from home on 'passion projects' such as her early childhood programme and will continue to do so for the rest of the year.

A source stressed that the entire Wales family are 'immensely grateful for the kind and thoughtful wishes they have received over the past nine months' and are grateful to the media for its cooperation in affording her space and privacy.

The princess was first admitted to hospital in January for what has only been described as planned abdominal surgery.

It was later discovered by doctors that cancer had been present and she embarked on her treatment in late February.

Kensington Palace has not confirmed whether the princess expects to return to a full programme of duties next year. It is understood that decisions about 2025 will be taken in line with medical advice.

However sources told the Mail tonight that the Princess hopes to do a small number of engagements shining a light on some of the causes, issues and charities that are closest to her heart over the coming months.

They are only likely to be announced last minute as they will depend as and when Her Royal Highness feels able to carry them out, with sources stressing repeatedly that every 'cancer journey is different'.

It is understood that she is also working with staff on plans for her annual carol concert in December.
