The 45-second film, named ‘Masters of Merry’, highlights the 311-year-old company’s heritage and expertise during the festive season.
It features original archive footage and illustrations from the 1950s, mixed with animation.
The film was put together alongside creative design agency Otherway and directed by Aardman Animations – renowned for its work on Wallace & Gromit.
Fortnum & Mason customer experience director Zia Zareem-Slade said: “This season has always been at the heart of Fortnum & Mason.
“The extraordinary food, the joy-giving gifts, the exceptional moments – the spirit of Christmas has been the catalyst in all that we do. And while many things will change in the next 300 years, Fortnum’s at Christmas is one thing that won’t.
“It’s a proud moment for the brand to see our spirit translated into film at Christmas – we hope it will resonate with customers old and new.”
