Here’s an early contender for this year’s Christmas No.1…

Hot off the success of his chart-dominating dance anthem Promises with Calvin Harris, Sam Smith is giving fans yet another new original song before the year is out.

The British singer-songwriter has recorded new track Fire On Fire, which will serve as the original song for BBC One’s remake of Watership Down.

“I am so excited and honoured to be a part of this new adaptation of Watership Down,” Sam said. “This story is so powerful and timeless, and it has been thrilling to work with Noam and his team and the incredible Steve Mac on this song for it. I hope everyone loves it as much as I do.”

The new song was recorded by Sam with the BBC Concert Orchestra at London’s Abbey Road Studios in September 2018.

The announcement coincides with the release of a first look at the highly anticipated remake, which boasts a stellar cast of British talent.

James McAvoy, John Boyega, Nicholas Hoult, Olivia Colman, Gemma Arterton, Sir Ben Kingsley, Daniel Kaluuya, Peter Capaldi, Mackenzie Crook, Miles Jupp, and Anne-Marie Duff will all voice rabbits in this new screen version of Richard Adams’ classic novel.

“It’s a real testament to the calibre of this adaptation of Watership Down that it has attracted such an exciting roll call of names to bring these much loved characters to life,” said Ben Irving, Executive Producer for BBC One.

“Now – in Sam Smith – we have one of the world’s most successful recording artists, with the perfect new song to serve as the series’ theme. BBC One viewers are in for a treat this Christmas.”

Watership Down will span two speacial feature length episodes this Christmas, which will air on BBC One.

This new adaptation is a co-production between BBC One and Netflix, with the streaming giant to premiere Watership Down worldwide outside of the UK.
