The actors joined forces for the upcoming film adaptation of the beloved stage show, based on T.S. Eliot's poetry, and getting to work with the screen icons as part of a star-studded cast left Corden in awe.
"That in itself would be ridiculous. Now imagine everyone's pretending to be a cat, and you do wonder if you're on some kind of hallucinogenic substance!"
Corden also enjoyed the sheer spectacle of the sets, which were specially created for director Tom Hooper. "They built a sort of street in London, and it was all to scale as if we were the size of cats," he explained. "The ambition of it (the movie) is the thing that I think is the most exciting thing, really."
"Cats", which uses computer-generated imagery to transform the actors into furry felines for the film, opens in theatres next week.
