The Game of Thrones star steps into the role of the fraudulent Defense Against the Dark Arts professor for Season 2, replacing Nicholas Hoult, who exited over scheduling conflicts.
Kit Harington is heading to Hogwarts. The Game of Thrones star has been cast as Gilderoy Lockhart in the second season of HBO’s Harry Potter series, taking over a role that had been filled only weeks earlier by Superman actor Nicholas Hoult.
According to Variety, Hoult stepped away from the project due to scheduling conflicts, with the actor currently committed to filming the Superman sequel Man of Tomorrow, in which he reprises his role as Lex Luthor. His departure came just a fortnight after his casting was first announced, leaving the production to move quickly to find a replacement for one of the wizarding world’s most memorable characters.
For Harington, the timing could hardly have been better. A self-described lifelong Harry Potter fan, the actor has spoken openly about his love of J.K. Rowling’s novels, which he first read as a child and has returned to many times since.
A character Harington already knows well
Unusually for a recast, Harington arrives already familiar with the part. He voiced Lockhart in Audible’s recently released full-cast audio edition of Harry Potter and the Chamber of Secrets, giving him the rare chance to play the same character across two very different mediums. That prior experience, he has suggested, made saying yes to the television role an easy decision.
Reacting publicly to the news for the first time, Harington did not hide his enthusiasm, describing himself as thrilled and calling Lockhart one of his favorite characters in the series. He has also acknowledged that portraying the professor physically, rather than through voice alone, presents a fresh and welcome challenge.
Gilderoy Lockhart is one of the most distinctive figures in the Harry Potter canon. A celebrated wizard renowned across the magical world for a long list of heroic deeds, he is appointed as the new Defense Against the Dark Arts teacher at Hogwarts, only for it to emerge that he is a vain fraud who took credit for others’ achievements after erasing their memories. The role was memorably played by Kenneth Branagh in Warner Bros.’ 2002 film adaptation, meaning Harington follows a well-loved screen performance.
Harington joins an already substantial lineup for the series. Newcomer Dominic McLaughlin leads the cast as Harry Potter, alongside Arabella Stanton as Hermione Granger and Alastair Stout as Ron Weasley, three young actors largely new to the screen. The adult roles are anchored by an array of established names, including John Lithgow as Albus Dumbledore, Janet McTeer as Minerva McGonagall, Paapa Essiedu as Severus Snape, and Nick Frost as Rubeus Hagrid.
Lockhart is not the only role to have been recast ahead of the second season. Earlier in the year, HBO announced it would recast Ginny Weasley after actress Gracie Cochrane exited the project, underscoring the natural reshuffling that comes with a long-running, large-ensemble adaptation still finding its feet.
The casting also continues Harington’s lengthy association with HBO. Beyond his star-making turn as Jon Snow in Game of Thrones, he has appeared in the historical drama Gunpowder and featured prominently in the third and fourth seasons of the network’s financial drama Industry, making his return to the HBO fold a familiar move.
What comes next for the series
The Harry Potter series is envisioned as a sprawling, multi-season adaptation, with each season broadly corresponding to one of Rowling’s seven novels. The first season, officially titled Harry Potter and the Philosopher’s Stone, is set to premiere on Christmas Day 2026, while the second, adapting Chamber of Secrets, is expected to begin filming this fall.
Behind the camera, the series has seen its own evolution. Jon Brown, a writer on the first season known for his work on Succession, has been elevated to co-showrunner for the second alongside Francesca Gardiner. With production on Season 2 approaching and Harington now attached, the adaptation continues to build momentum ahead of its hotly anticipated debut later this year.
