The HBO Harry Potter series has made a major casting change for its second season. Kit Harington, known worldwide for playing Jon Snow in Game of Thrones, will now play Professor Gilderoy Lockhart. He replaces Nicholas Hoult, who had to leave the project because of scheduling problems.
This news came as a surprise to many fans. Hoult was only announced as Lockhart a few weeks ago. Now, Harington is stepping into the role. The interesting part is that Harington has already played this character before. He voiced Gilderoy Lockhart in the Harry Potter: The Full-Cast Audio Editions that came out last year.
Why Nicholas Hoult Left the Harry Potter Series
Nicholas Hoult was originally chosen to play Gilderoy Lockhart in Season 2. But things changed when the production schedule shifted. HBO had to work around two other projects that Hoult was already committed to. When the filming dates for Lockhart’s scenes had to move, it became impossible for Hoult to stay in the role. The studio let him out of his contract.
Hoult is currently busy with other big projects. He is playing Lex Luthor in James Gunn’s Superman movie Man of Tomorrow. He is also working on other films. The scheduling conflict meant he could not continue with the Harry Potter series. HBO then reached out to Harington, who was available and very excited to take over.
Kit Harington’s Connection to Gilderoy Lockhart
Kit Harington is not new to the world of Harry Potter. He voiced Gilderoy Lockhart in the full-cast audio editions of the Harry Potter books. These audiobooks were released in 2025 and featured many famous actors.
Harington has been a Harry Potter fan since he was a child. He said he was the same age as Harry when the first book came out. He read it and became a huge fan. He has reread the books many times over the years.
“I read it, and like so many generations, I was entranced, and then I was a huge fan all through my teenage years.”
When asked about voicing Lockhart in the audiobooks, Harington said it was an easy decision.
“It was a really simple yes, because I love the character. As far as cameos in a series go, you don’t get much more entertaining and fun to do as an actor than Gilderoy Lockhart. It was a no-brainer.”
He also said, “I think there’s a little bit of Gilderoy Lockhart in all of us”.
Who Is Gilderoy Lockhart?
For those who may not remember, Gilderoy Lockhart is a major character in the second Harry Potter book, Harry Potter and the Chamber of Secrets. He is the new Defence Against the Dark Arts professor at Hogwarts.
Lockhart is known for being very vain and obsessed with fame. He has written many books about fighting dark creatures. He claims to have done many heroic things. But it soon becomes clear that he is not qualified for the job. He is actually a fraud who uses Memory Charms to steal other people’s stories. He also won Witch Weekly’s Most Charming Smile Award five times.
In the 2002 movie Harry Potter and the Chamber of Secrets, Lockhart was played by Kenneth Branagh. Now, Harington will bring his own version of the character to the HBO series.
What This Means for Harry Potter Season 2
Season 2 of the HBO Harry Potter series will adapt Harry Potter and the Chamber of Secrets. Filming for the second season is set to begin in fall 2026. The first season will premiere on Christmas Day, December 25, 2026, on HBO and will stream on HBO Max.
Dominic McLaughlin will play Harry Potter. Alastair Stout will play Ron Weasley. Arabella Stanton will play Hermione Granger. Other cast members include John Lithgow as Albus Dumbledore, Paapa Essiedu as Severus Snape, Janet McTeer as Professor McGonagall, and Nick Frost as Rubeus Hagrid.
Jon Brown, who wrote for the first season, has been promoted to co-showrunner for Season 2. He will work with showrunner Francesca Gardiner. The series is produced by HBO in association with Brontë Film and TV and Warner Bros.
Fan Reactions to the Casting Change
Fans have been reacting to the news of Harington replacing Hoult. Many are excited to see the Game of Thrones star join the Harry Potter universe. Some fans pointed out that Harington already voiced Lockhart in the audiobooks, so he already knows the character well. Others are curious to see how he will compare to Kenneth Branagh’s version from the movies.
Some fans were disappointed to see Hoult leave the project. He was only announced as Lockhart in early August 2026. But most understand that scheduling conflicts happen in Hollywood. The recasting has created a lot of buzz online. Many are now looking forward to seeing Harington bring the charming but fraudulent professor to life on screen.
The Growing Cast of the Harry Potter Series
The HBO Harry Potter series has been building an impressive cast. The show held auditions for the three main roles and saw more than 30,000 young actors. The final choices were McLaughlin, Stout, and Stanton.
The adult cast includes many well-known actors. John Lithgow will play Albus Dumbledore. Paapa Essiedu will play Severus Snape. Janet McTeer is in talks to play Minerva McGonagall. Nick Frost will play Rubeus Hagrid. The show is also bringing back Warwick Davis as Flitwick.
The series is described as a “faithful adaptation” of J.K. Rowling’s books. It will cover one book per season. The first season will cover Harry Potter and the Philosopher’s Stone. Season 2 will cover Chamber of Secrets.

A Unique Recasting Situation
This recasting is unusual because Harington has already played Lockhart in another format. He voiced the character in the audiobooks. This means he already has a feel for the character’s personality and voice. He knows Lockhart is vain, boastful, and not very talented.
Harington’s experience with the audiobooks may help him prepare for the TV series. He already understands Lockhart’s role in the story. He knows that Lockhart is a fraud who takes credit for other people’s work. This knowledge could make his performance even better.
The series is still in production. Season 1 is set to release this Christmas. Season 2 will begin filming this fall. Fans will have to wait a bit longer to see Harington as Lockhart. But the news has already created a lot of excitement.
