12 Harry Potter Actors Who Were Replaced In The Sequels
9. Emily Dale - Katie Bell
The Replacement: Georgina Leonidas
The first two Harry Potter films featured Emily Dale as Katie Bell when the role was largely just a background figure without any lines. She was then replaced with an unnamed actress for the third film, when Katie ends up being hit by lightning in the Quidditch match and is seen in hospital after the match.
For The Half-Blood Prince, Georgina Leonidas - a more established actress with a handful of credits to her name - took on the role and kept it for The Deathly Hallows.
As with Lavender Brown, it was likely a case of an extra being replaced with an actual actor when the role required more performance.
Confusingly, Bell actually swaps years in the films, joining Harry for a Potions class despite being in the year above him. But then she did miss six months of school when she was accidentally cursed, so thats maybe forgivable.
