A behind-the-scenes video has been released for the upcoming star-studded Cats movie and it features Idris Elba and Taylor Swift dancing their socks off.
The video was released by Universal Pictures on Wednesday and introduces the cast, which boasts big-hitters from the world of film and music including Judi Dench, Jennifer Hudson, Ian McKellen, Jason Derulo, Rebel Wilson and James Corden, as well as giving viewers a peek at the making of the film.
Swift, who is playing a character named Bombalurina, reveals she came straight off her Reputation stadium tour into rehearsals.
She also spoke about her love of performance, saying: "My first memories of performance go back to when I was in Pennsylvania growing up.
"My favourite thing was getting to be theatrical, to tell a story and I've always brought that narrative element to my live shows."
The Shake It Off hitmaker added: "This musical is timeless and we've got to update it in ways that are just so, so great."
Meanwhile, Judi Dench tells how being cast in Hooper's film adaptation of the musical gave her a second chance as she had been cast as Grizabella in the original West End production in the '80s but had to pull out due to an injury.
"I was cast in 1981. Just before we opened I snapped my Achilles tendon and I thought that was my history with Cats," she says during a behind-the-scenes interview.
"But it turns out not to be. It's a kind of Alice In Wonderland experience."
Cats is out in cinemas in Ireland on December 20.
