These "Cats" can dance!

Universal released a behind-the-scenes video for the highly anticipated adaptation of Andrew Lloyd Webber’s musical. The teaser features stars Jennifer Hudson, Taylor Swift, Idris Elba, Judi Dench, James Corden, Rebel Wilson, Ian McKellen, and Jason Derulo.

There's no fur, but the video provides a glimpse at Swift and Elba practicing dance choreography for their duet as Bombalurina and Macavity. We also see the sets that were built to scale to actual cat size, so there are huge chairs and tables.

Director Tom Hooper will digitally add fur to the actors, an intriguing (possibly very weird) choice that we'll hopefully see when the first trailer drops this Friday.

It has has continuously appeared on stage around the globe, having played to 81 million people in more than 50 countries and in 19 languages.

"Cats" the movie opens in theaters December 20.
