Helen McCrory now
Initially, Helen had been cast as Bellatrix, but her pregnancy meant she had to pull out; they recast the actress to play Narcissa two years later. Like many other actresses from the franchise, Helen has expanded her roles to include appearances on stage but has still managed to dominate the movie and TV world, too. The actress has appeared in the James Bond film Skyfall, as well as The Woman in Black: Angel of Death. When not acting, Helen puts a lot of her time towards helping children’s charities.
