Why Kate’s personal video marks strikingly different approach

This is clearly a well-planned approach to releasing information, with the filming by Will Warr taking place in Norfolk last month, and the changes of clothes suggesting more than one filming session.

It’s a world away from old school royal releases which stuck to the barest of details and stayed as dry as the desert.

This much lusher treatment follows the trend of celebrities and public figures taking their messages straight to the public, using the language of social media rather than conventional news or an interview.

It allows a great deal of control over the message – with evocative music and slick editing driving the story forward, rather than any questions that might arise about her health or treatment.

We see Catherine, in a 1970s-style long flowing dress, spending time with her family in the woods and by the beach, playing a game with her own parents.

These are framed in a relatable way – a family relaxing after really tough times, in a rural setting that’s meant to send a message about the soothing powers of nature.

Over the top of the pictures is Catherine’s narration, in a movie voiceover style, capturing her sense of cautious optimism, as she welcomes the end of her chemotherapy while at the same time recognising the fragility of life.

It’s where Norfolk meets Hollywood plus Instagram.
