And then there was the rest of it. “We were going to have big top teeth all the way across but in the course of extra teeth being fitted I said I quite like it with only half in because it gave me a kind of Elvis sneer,” Ferris continued. “So we left just the one side of extra teeth in and it did a wonderfully cruel thing to my mouth.” It certainly did.
In fact, Ferris’s transformation and her performance as an evil villain ended up standing her in very good stead. Because just a few years after Matilda, she was called upon to play another thoroughly unpleasant woman. This time, it was a certain famous wizard’s vile Aunt Marge in 2004’s Harry Potter and the Prisoner of Azkaban.
Ferris’ turn as Aunt Marge also required the actress to look quite unlike herself. This time, however, it was even more of a dramatic transformation, as Aunt Marge ends up being turned into a balloon by her nephew. In fact, it was even downright dangerous at times. “I had several suits of latex which they put compressed air between to expand me. It was absolute torture. And I passed out. It had never been done before, you see,” Ferris told the Metro in 2017.
