From the new Illustrated Edition of Harry Potter and the Order of the Phoenix: The portrait of Dolores Umbridge

Quote from Selynn

I agree Umbridge in the movie looks too nice even though she was a great actress, this Umbridge looks actually fits the description in the book. Creepy and ugly.

I do kind of like that movies were toned down tbh.

Shows that "nice" looking people can still be nasty. Awful people can be anyone. There's a bit of realism to that portrayal imo.
