Jason Derulo, who plays the swaggering cat, The Rum-Tum-Tugger, says "I've always been obsessed with singing and dancing, but it all started with me in the kitchen with my socks on trying to do the moonwalk!"

Jennifer Hudson and Idris Elba have been in rehearsals where they have to dance and perform cat-like actions.

Francesca Hayward the English ballerina plays one of the main characters, Victoria. She is a principal dancer in the Royal Ballet.

The show was first performed in 1981 and was written by world-famous composer Andrew Lloyd Webber.

Having run for a whopping 38 years, it is one of the West End's longest running musicals.

It was based on poet T. S. Eliot's Old Possum's Book of Practical Cats, and is about a group of feline characters who gather at an event called the "Jellicle Ball".

Tom Hooper says the film uses the most advanced "digital fur technology" ever seen to bring the characters to life.

The reaction to the trailer has been pretty mixed so far!

Many people have said they are confused about how clothing works in the Cats universe, as many are wearing jackets and shoes, and others don't have any clothes on at all!

Some people have also said it looks slightly scary - particularly Idris Elba's character, Macavity.

Someone on Twitter said they felt a "jumble of emotions ranging from horror to befuddlement"!

Cats is out in UK cinemas in December.

So what do you think? What do you think about the costumes?
