Earlier on we talked about Ellie Darcey-Alden appearing as the young version of Harry Potter's mother in the movies. Here's Geraldine Somerville, who played her as an adult. Her death at Voldemort's hands is arguably the pivotal moment in Harry's whole destiny, leading to his final avenging of the act at the climax of the series. She mostly appears in flashbacks, although as Harry heads to his final battle she appears to him directly as a vision in the forest.
Somerville is generally known for playing tougher roles, most notably in the dark British police drama "Cracker" and has worked steadily throughout her career without ever ascending to superstardom. She took particular delight in her Harry Potter role and says that all of her own real-life children have grown up to be huge fans of the stories.
