Harry Potter Season 2 Recasts Gilderoy Lockhart: Kit Harington Replaces Nicholas Hoult

Why did Nicholas Hoult leave the role?

Scheduling conflicts, according to Deadline, which first reported the recast. Hoult was announced as Lockhart earlier this month, but shifting production schedules created a conflict with other commitments, reportedly including Man of Tomorrow, James Gunn's next Superman film, in which Hoult reprises his role as Lex Luthor alongside David Corenswet and Milly Alcock.

Has Kit Harington actually played this character before?

In a sense, yes. Harington voiced Gilderoy Lockhart in Harry Potter: The Full-Cast Audio Edition of Chamber of Secrets, released in December 2025. So while this marks his first time playing the role on screen, it isn't his first time inhabiting the character at all, a detail that gives the recast a bit more continuity than a cold, unrelated casting choice.

Who played Lockhart in the original films?

Kenneth Branagh, in 2002's Harry Potter and the Chamber of Secrets. Branagh's take on Lockhart, vain, fame-obsessed, and ultimately exposed as a fraud who erased people's memories to steal credit for their accomplishments, remains a well-loved, specific comic performance, which means Harington is stepping into a role with a genuinely beloved prior interpretation to measure against.

Is this the only recasting the show has made so far?

No, it's the second. In May, HBO announced it would recast Ginny Weasley ahead of Season 2 filming, after actress Gracie Cochrane exited the role due to what the network described as "unforeseen circumstances." A replacement for Ginny hasn't been announced yet.

When does the series actually premiere, and how does Season 2 fit in?

Season 1, titled Harry Potter and the Philosopher's Stone, premieres this Christmas on HBO and HBO Max, with the series described as a "faithful" adaptation of J.K. Rowling's novels. Season 2, adapting Chamber of Secrets, already received an early greenlight in May, with filming set to begin this fall, meaning Harington will start working almost immediately after Season 1 debuts.

Who's already confirmed in the cast?

Dominic McLaughlin plays Harry Potter, with Alastair Stout as Ron Weasley and Arabella Stanton as Hermione Granger. The adult cast includes John Lithgow as Albus Dumbledore, Janet McTeer as Minerva McGonagall, Paapa Essiedu as Severus Snape, and Nick Frost as Rubeus Hagrid. Season 1 writer Jon Brown, also known for Succession and The Franchise, has been elevated to co-showrunner alongside Francesca Gardiner for Season 2.

Is this a good fit for Harington, given his prior roles?

Genuinely divisive among early reactions, and worth noting honestly rather than assuming universal approval. Some critics have pointed out that Harington has built a career playing brooding, often morally serious characters, think Jon Snow in Game of Thrones, and questioned whether that register translates to Lockhart's specific blend of comic vanity and hidden cruelty. Others point to his audiobook performance and his history of playing more comedic, self-important characters in smaller roles as evidence he can pull off the tonal shift. Given the show doesn't premiere until Christmas, and Lockhart's Season 2 material is still a year-plus away, there's genuine time before we'll actually see how it lands.
