Richard Curtis is making his first Christmas film since Love Actually and, of course, it is packed full of A-list celebrities.
The animation, which is set to be released on Netflix later this year, follows a series of entwined tales about love, loneliness, family and friends, all while Santa is trying to solve some big problems of his own.
Succession megastar Brian Cox will be playing Father Christmas, while Love Actually’s Bill Nighy, Killing Eve’s Fiona Shaw and former Doctor Who Jodie Whittaker will all have starring roles.
It has also been revealed that Ed Sheeran has made a brand new song for the film, which he created with his older brother.
Speaking about the opportunity the popstar said: ‘I got to work with my older brother on this which is such a rarity and a gift to work so closely with my only sibling.
‘It felt so good to create something my children would watch, with their uncle, based in the country they live in.
‘I find it mad that there isn’t more animated Christmas films for kids, but this is going to become a holiday staple, at least in our household.
‘Hope everyone loves it, and enjoys the song, we had such a great time creating it.’
The 33-year-old even teased a little bit about the film and the scene the song was written for in particular, describing it as ‘heartbreaking’ but ‘real’.
‘[it’s] so emotional, yet so heartwarmingly 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.
‘The scene that we wrote this song for is so heartbreaking, but so real for many people at Christmas, spending it without the ones they love, for so many reasons.’
While Curtis was delighted that ‘the greatest British songwriter’ had agreed to get involved in the movie, claiming the duo ‘had been friend for years’.
‘I’m so thrilled to have Ed’s beautiful song in our movie.
‘It’s a film set in Suffolk … Ed lives in and loves Suffolk and completely understood the pitch and tone of what we were trying to do.
‘We’ve been friends for many years and – especially now that he’s a husband and a father – it’s really lovely to have him play such a key part in this film about love, children and family.
‘And, of course, even if he wasn’t a friend and didn’t love Suffolk, how marvellous to have a wonderful new song by one of the greatest British songwriters ever.’
That Christmas has been directed by Simon Otto, who also animated How To Train Your Dragon, and the score has been composed by John Powell.
