Fiona Shaw as Petunia Dursley
Growing up alongside a magical sister made Petunia jealous, and she didn’t want to have any connections to the wizarding world later in life. That was impossible, however, since Albus Dumbledore entrusted her with the task of taking care of Harry after his parents were killed by Lord Voldemort. Petunia and her husband Vernon never took good care of their nephew and kept his magical abilities secret from him for years.

Shaw always enjoyed the stage, and appeared in several well-received plays after she waved goodbye to the Harry Potter franchise. She also starred in Oscar-nominated movie The Tree of Life and hit TV shows True Blood and Killing Eve.
Anna Shaffer as Romilda Vane
Anna Shaffer made her film debut as Gryffindor student Romilda Vane in the Half-Blood Prince and reprised her role in the final two movies. Romilda had a huge crush on Harry and decided to make him like her back the only way she knew how. She gave him chocolates spiked with a strong love potion, but Ron ended up eating them instead, leading to a hilarious result.
