Taylor Swift is quite proud of her time on the set of Cats. 

The Grammy winner — who will turn 30 on Friday — took to Instagram on Tuesday to share a throwback photo of herself on the first day on set of the musical fantasy film, which is an adaptation of Andrew Lloyd Webber‘s musical of the same name. In the photo, Swift is seen reaching up to touch the knob of a giant door.

“Basically, Bombalurina is one of those really mischievous cats you see in internet videos who has figured out how to open human doors,” wrote Swift, referencing her character.

Directed by Tom Hooper (The King’s Speech, Les Miserables), Cats also stars Judi Dench, James Corden, Jason Derulo, Idris Elba, Jennifer Hudson, Ian McKellen and Rebel Wilson. The first trailer for the film, which was released earlier this year, drew severe mockery from fans on Twitter who called it “creepy” because of how it portrayed the actors with cat costumes. Cats will be released nationwide on Dec. 20.
