Global music icon Taylor Swift and legendary composer Andrew Lloyd Webber release their new original song, “Beautiful Ghosts” for the Cats movie.

Cats, in theaters December 20, is directed by Oscar®-winning filmmaker Tom Hooper (Les Misérables, The King’s Speech), and stars Swift, James Corden, Judi Dench, Jason Derulo, Idris Elba, Jennifer Hudson, Ian McKellen, Rebel Wilson and Royal Ballet principal dancer Francesca Hayward.

In the film, the song is performed by Hayward, who stars in the role of Victoria. The version of the song performed by Swift, who plays Bombalurina in the film, will play over the end titles.

As part of the release, an official lyric video has launched to accompany the song.

A behind-the-scenes video documenting the creation and recording of “Beautiful Ghosts,” including an interview with Swift, Lloyd Webber and Tom Hooper, can also be viewed here.

One of the longest-running shows in West End and Broadway history, the stage musical “Cats” includes some of Lloyd Webber’s most indelible songs, including “Memory.” Lloyd Webber, Swift and the filmmakers were excited at the idea of introducing a new song for the film adaptation.

Lloyd Webber saw an opportunity to create a new signature song for Victoria, whose character has been expanded for the film. “When I first read the screenplay, the first thing I said was, ‘We have to have a song for Victoria.’ “Beautiful Ghosts,” he says, is now, “an incredibly important and central part of the whole film.”

For director Tom Hooper, the song exceeded even his high expectations. “What I couldn’t believe was the extraordinary beauty of these lyrics that Taylor had written,” Hooper says. “It was as if someone had come into the film I was in the middle of making and … had reflected back to me a profound understanding of what we are trying to do with the movie. It was utterly thrilling.”
