Rachel Moore, who was walking her dog when she spotted the film crew, said: "The seafront was cordoned off with security guards.

"It was an unexpected treat to see such an iconic filmmaker with an equally iconic music maker while walking the dogs.

"I'm looking forward to seeing what this Suffolk collaboration is all about."

Speaking on Curtis approaching him with the film, Sheeran previously said: “He came to me two years ago to play me the rough of That Christmas. It was just sketches and voices, but it blew me away.

“So emotional, yet so heart-warmingly funny, like all Richard Curtis movies. I find since having kids, there’s a real lack of great animated children’s Christmas movies, so I thought this was such an amazing thing to make and put into the world."

Curtis is best known for directing romantic comedies including Love Actually, Four Weddings and a Funeral, Notting Hill and About Time.
