I’ve no idea who that actress is, but she looks a lot like a prissy busybody ranch neighbor of ours when I was a kid-the bitch would call my mom and/or aunt every time we climbed onto the top of the wall around her citrus orchard and ran along it, teasing her scary, kid-hating bulldog-one of those bigger American ones, not an old English...
That’s the character she played in a Harry Potter movie. She was very mean!
You really need to read the Harry Potter books. Excellent series.
