Emma Thompson spoke about the downsides to filming the upcoming movie “Cruella” during an appearance on Monday’s “Tonight Show”.

Thompson plays Baroness in the much-talked-about flick, and the role involves wearing a lot of corsets, according to the actress. She also said the ensembles, including some very large wigs, make it very difficult for her to go to the bathroom.

The British star said, “You bend down and try to reach, but then you’re like a giraffe because you can’t get your head back up.

Thompson also spoke about getting George Michael’s blessing before making the movie “Last Christmas” — based on the iconic Wham! track.
