Yes, dear reader, this is almost definitely why she seems familiar.
In 2001, Warner Brothers released “Harry Potter and the Sorcerer’s Stone,” the first of eight films based on the seven fantasy novels written by J. K. Rowling (the last book got two movies, a move which everyone in Hollywood is still copying and pasting almost two decades later). The overarching story follows young Harry Potter (Daniel Radcliffe) as he discovers that magic is real and that he’s a wizard and that a quasi-immortal eugenicist, Lord Voldemort (hey, there’s Ralph Fiennes again!) wants him dead. But before he ever steps foot in Hogwarts School of Witchcraft and Wizardy, before he ever meets his best friends Ronald Weasley (Rupert Grint) and Hermione Granger (Emma Watson), he has to deal with his very abusive, very non-magical extended family, the Dursleys.
Fiona Shaw portrays Petunia Dursley, Harry’s gossip-loving aunt. She’s a cruel, jealous woman who cherishes her bitterness against her late sister — Harry’s mother, who had fantastical powers while Petunia did not — by taking it out on her nephew. Very briefly, toward the end of the series, it almost seems as though she might regret her actions, just a little bit, but in neither the movies nor the books is there a true redemption arc for this wretched person.
