Every Actor Recast In The Harry Potter Movies

by

The Harry Potter movies were a huge success, entertaining audiences around the world for over ten years. Warner Bros. turned J.K. Rowling’s magical stories into eight blockbuster films that became iconic for a whole generation, making stars out of Daniel Radcliffe, Emma Watson, and Rupert Grint, and featuring many of Britain’s best actors. Now, a new Harry Potter TV series is in the works at HBO, aiming to be even more true to the original books. Dominic McLaughlin, Alastair Stout, and Arabella Stanton will play the new Harry, Ron, and Hermione, and the show will also star well-known actors like John Lithgow as Dumbledore and Paapa Essiedu as Snape, offering fresh perspectives on these cherished characters.

The new HBO series will have an entirely new cast, but the original movies also saw actors come and go. It was incredibly difficult to keep such a large group of performers for ten years, so many were replaced between films. Some changes were minor and barely noticeable, while others were more significant due to unexpected events or changes in the story.

20) Alicia Spinnet

The early Harry Potter films aimed for consistency in Quidditch teams, but scheduling issues with the young actors sometimes caused changes. In the first film, Leilah Sutherland played Alicia Spinnet, a Gryffindor Chaser who helped her team win. However, by the second film, Rochelle Douglas had taken over the role without much notice. As Quidditch became less important to the story in later films – with the focus shifting to Voldemort’s return – the change in actors playing Alicia Spinnet wasn’t really noticed by most viewers.

19) Ernie MacMillan

As a huge Harry Potter fan, I always appreciated the smaller roles that really built out the world. It’s easy to overlook the Hufflepuffs, but Louis Doyle did a fantastic job making Ernie MacMillan stand out in Chamber of Secrets – he was just so perfectly… official-sounding! Doyle came back for Goblet of Fire, and he really nailed Ernie’s tendency to jump to the wrong conclusions during all the Triwizard Tournament drama. Then, in Deathly Hallows, Jamie Marks took over for the Battle of Hogwarts, and even though Ernie wasn’t a big part, seeing a Hufflepuff standing with Harry really showed their loyalty. It’s those little details that always stuck with me.

18) Mafalda Hopkirk

Audiences first encountered Mafalda Hopkirk in Harry Potter and the Order of the Phoenix through a harsh voice delivered via Howler, performed by Jessica Hynes. Later, in Harry Potter and the Deathly Hallows: Part 1, the character became a physical presence when Harry, Ron, and Hermione snuck into the Ministry of Magic. Sophie Thompson took on the role, portraying a nervous and tense bureaucrat as Hermione tried to conceal her identity within the unfriendly government building.

17) Elphias Doge

The Order of the Phoenix needed many dedicated members, and Peter Cartwright played a small role as Elphias Doge, helping to bring Harry to Grimmauld Place in the fifth movie. Later, when the script for Harry Potter and the Deathly Hallows: Part 1 required a lot of background information about Dumbledore’s family, they hired experienced actor David Ryall. Ryall perfectly portrayed a sense of world-weariness and importance at Bill Weasley’s wedding, giving Harry his first hints that Dumbledore had a complicated history.

16) Mr. and Mrs. Granger

In the Harry Potter books, Hermione’s parents aren’t very developed characters. However, Tom Knight and Heather Bleasdale brought them to life in a memorable scene during the Diagon Alley visit in Harry Potter and the Chamber of Secrets. Later, in Harry Potter and the Deathly Hallows: Part 1, the scene where Hermione modifies her parents’ memories needed a more somber approach. Ian Kelly and Michelle Fairley stepped into the roles, and Fairley especially conveyed the sadness of the moment with her expression as the spell took effect.

15) Katie Bell

In Harry Potter and the Half-Blood Prince, a crucial scene required a powerful physical performance from Georgina Leonidas, who took over the role of Katie Bell. While Emily Dale played Katie in the first two films, mostly as a background character during Quidditch games, Leonidas needed to convincingly portray the terrifying experience of being possessed by a cursed necklace meant for Albus Dumbledore (Michael Gambon). This change in actors was necessary to match the darker and more intense atmosphere of the sixth movie.

14) Angelina Johnson

In Harry Potter and the Goblet of Fire, Fred Weasley (played by James Phelps) asked Angelina Johnson to the Yule Ball, giving her character more attention. While Danielle Tabor initially played the Gryffindor Quidditch player, establishing her as a strong competitor in the first three films, Tiana Benjamin took on the role for the Yule Ball scenes, bringing a more glamorous feel. Unfortunately, due to other work commitments, Benjamin couldn’t continue with the part, meaning Angelina Johnson’s story wasn’t shown in the later Harry Potter movies.

13) Padma Patil

Many Ravenclaw fans were frustrated when the movie Harry Potter and the Prisoner of Azkaban placed Padma Patil in Gryffindor, despite her being a Ravenclaw in the books. The actress Sharon Sandhu played her in that film. Later, in Harry Potter and the Goblet of Fire, Afshan Azad took on the role of Padma Patil and continued playing her throughout the rest of the series. Azad did a great job portraying Padma’s obvious boredom with Ron Weasley at the Yule Ball, which made the scene feel more realistic and captured the awkwardness of being a teenager at a formal event.

12) Parvati Patil

In Harry Potter and the Prisoner of Azkaban, Sitara Shah played Parvati Patil, notably during the lesson with the Boggart. The role of Parvati Patil grew much larger in Harry Potter and the Goblet of Fire, and Shefali Chowdhury took over, even appearing as Harry’s date. Chowdhury continued playing Parvati throughout the rest of the series, becoming an active member of Dumbledore’s Army and fighting in the final battle, transforming the character from a minor background role into a more developed one.

11) Bill Weasley

Bill Weasley was first seen in the Harry Potter films as a quick photograph in Prisoner of Azkaban, with an actor briefly appearing in a newspaper clipping. It wasn’t until Deathly Hallows that fans finally saw him as a character, played by Domhnall Gleeson. This casting was a clever nod to the audience: Domhnall Gleeson is the son of Brendan Gleeson, who played Mad-Eye Moody, creating a real-life father-son connection mirroring the characters’ relationships within the Order of the Phoenix.

10) The Grey Lady

Helena Ravenclaw, also known as The Grey Lady, started as a minor character in the first Harry Potter film, played by Nina Young. However, her importance grew significantly in the final movie, Harry Potter and the Deathly Hallows: Part 2. Actress Kelly Macdonald took on the role and brilliantly portrayed the tragic backstory of the founder’s daughter, revealing her knowledge of a lost artifact. Macdonald’s performance transformed what could have been a quick scene into a crucial moment in the story, adding depth and emotion to the character.

9) Pansy Parkinson

Pansy Parkinson is the Hogwarts student who has been played by the most different actresses – a total of four throughout the Harry Potter films. Katherine Nicholson played her in the first two movies, and Genevieve Gaunt provided the character’s voice in Harry Potter and the Prisoner of Azkaban. Lauren Shotton had a brief, silent role in Harry Potter and the Order of the Phoenix, before Scarlett Byrne took on the part for the last three films. Byrne is well-known for delivering Pansy’s famous demand that Harry be turned over to Voldemort, which cemented the character’s place as one of the most disliked students at Hogwarts.

8) Aberforth Dumbledore

The Hog’s Head Inn is a rather rundown pub, and the original actor to play its grumpy bartender was Jim McManus in Harry Potter and the Order of the Phoenix. Later, audiences discovered this character was actually Aberforth Dumbledore, the brother of Headmaster Albus Dumbledore. In the important rescue scenes from Harry Potter and the Deathly Hallows: Part 2, Ciarán Hinds took on the role, bringing the seriousness needed to reveal the heartbreaking story of Ariana Dumbledore and challenge the Golden Trio’s unquestioning trust in Albus.

7) Tom the Innkeeper

When Alfonso Cuarón became director, the look and feel of the Leaky Cauldron changed dramatically. In the first Harry Potter film, Tom the Innkeeper, played by Derek Deadman, was a fairly normal-looking character who welcomed Harry. But in Harry Potter and the Prisoner of Azkaban, Jim Tavaré played Tom as a completely different person – a hunched, bald, and quirky man who even talked to doorknobs. This big change in how the character looked showed audiences that the films were moving away from the style of the earlier movies and into a more unusual and imaginative direction.

6) The Fat Lady

To get into the Gryffindor common room, you need to know the password. The character guarding the entrance, the Fat Lady, got a noticeable makeover between the first few movies. In the first film, Elizabeth Spriggs played her as a traditional portrait. But in Harry Potter and the Prisoner of Azkaban, the hilarious Dawn French took on the role. French really embraced the quirky nature of the wizarding world, portraying the Fat Lady as an over-the-top opera singer who seemed to prefer shattering glass with her voice to actually letting students inside.

5) Griphook

While Warwick Davis is widely known as Griphook the goblin in the later Harry Potter films, Verne Troyer originally played the character physically in Harry Potter and the Sorcerer’s Stone, with Davis only providing the voice. For Harry Potter and the Deathly Hallows, where Griphook had a larger role, the filmmakers decided it would be easier for Davis to perform both the physical role and the voice, creating a more consistent portrayal.

4) Lavender Brown

The Harry Potter films are generally free from controversy regarding whitewashing, but the recasting of Lavender Brown remains a sensitive topic. In earlier films, Harry Potter and the Chamber of Secrets and Harry Potter and the Prisoner of Azkaban, the character appeared as a student in the background and was played by Black actresses Kathleen Cauley and Jennifer Smith. However, when Lavender Brown’s role became more significant as Ron Weasley’s girlfriend in Harry Potter and the Half-Blood Prince, the producers cast Jessie Cave, a white actress. While Cave’s performance was very funny, many fans were disappointed that a character who had been portrayed by Black actresses was replaced with a white actress as her role grew.

3) Tom Riddle

One of the most memorable parts of Harry Potter and the Chamber of Secrets was seeing a young Tom Riddle, brought to life by Christian Coulson’s captivating performance. However, by the time Harry Potter and the Half-Blood Prince was being filmed, Coulson was too old to convincingly play a teenager again. Frank Dillane took over the role for scenes showing Riddle’s past, portraying him as less outwardly charming and more clearly disturbed. Dillane’s performance, with Riddle’s cold, vacant stare, foreshadowed the dark villain he would eventually become.

2) Lord Voldemort

In the first Harry Potter film, The Sorcerer’s Stone, a frightening image of Lord Voldemort – a face clinging to the back of a turban – haunted viewers. This was brought to life by Richard Bremmer, who provided both the character’s chilling voice and unsettling appearance. Later, in Harry Potter and the Goblet of Fire, Ralph Fiennes took over the role, presenting a fully-bodied Voldemort. Fiennes moved away from the mysterious, cloaked look, instead delivering a powerful performance characterized by graceful movements and explosive anger, establishing Voldemort’s control over his followers.

1) Albus Dumbledore

The death of Richard Harris dramatically changed the character of Albus Dumbledore in the Harry Potter films. Harris initially portrayed Dumbledore as a warm, playful grandfather in the first two movies. When he passed away in 2002, Michael Gambon took over the role starting with Harry Potter and the Prisoner of Azkaban. Gambon intentionally didn’t imitate Harris, instead creating a Dumbledore who was strong, occasionally unpredictable, and weighed down by the challenges ahead. While some fans who closely followed the books didn’t like this new take, it matched the increasingly serious tone of the films.
