12 Harry Potter Actors Who Were Replaced In The Sequels
4. Genevieve Gaunt - Pansy Parkinson
The Replacement: Scarlett Byrne
Secondary Hogwarts pupil villain Parkinson was everything JK Rowling hated about the girls at school who had bullied her: it was that hatred that ultimately meant she wasn't allowed to marry Draco Malfoy, according to the writer.
The character - who was described as "pug-faced" in the books - was actually played by four actresses across the films. She first appeared in Chamber Of Secrets, played as a background extra by Katherine Nicholson, though that doesn't really count.
For the character's first legitimate appearance in The Prisoner Of Azkaban she was played by Genevieve Gaunt, who was first replaced by Lauren Shotton in the follow-up (though she didn't speak in what was mostly a cameo).
For Half-Blood Prince and the final two films, Scarlett Byrne stepped in for the more expanded role, and captured that hatefulness Rowling painted in her perfectly.
