Kit Harington joins HBO's Harry Potter series as Gilderoy Lockhart. Discover why the Game of Thrones star took over the Season 2 role.
Former Game of Thrones star Kit Harington is officially stepping into the Wizarding World, joining the cast of HBO's upcoming Harry Potter television adaptation as the charmingly vain Gilderoy Lockhart for Season 2. Warner Bros. Television and HBO are producing the multi-season reboot to explore J.K. Rowling’s original novels in far greater depth than the original feature films. Harington replaces actor Nicholas Hoult, who originally held the role before stepping down due to scheduling conflicts with James Gunn’s Superman.
What Is Kit Harington's Role in HBO's Harry Potter Series?
Kit Harington will portray Gilderoy Lockhart, the famously self-absorbed author and appointed Defence Against the Dark Arts teacher who makes his main debut during the events of Harry Potter and the Chamber of Secrets. The role was previously made famous on the big screen by Kenneth Branagh in the 2002 film adaptation.
During a recent guest appearance on Josh Horowitz's Happy Sad Confused Podcast, Harington described his decision to accept the casting offer as a very simple choice:
"When I knew they were doing this show, I was like, 'I think that's a brilliant idea; I think they can really delve into it further than the films did.' I'm fully supportive of it. And then I got called to be in it, and that was just a very simple, 'Yes, please!'"
Harington joked about how natural it felt to step into the boots of the pompous wizard, describing Lockhart as a character who is fundamentally "addicted to himself."
Why Did Kit Harington Take Over the Gilderoy Lockhart Role?
Harington's connection to the wizarding franchise stretches back to his childhood, but his personal affection for the universe deepened in adulthood through audio formats.
- Nightly Audiobook Ritual: The actor confessed that listening to Stephen Fry's classic narration of the Harry Potter audiobooks is a fixed part of his nightly routine to help his mind wind down.
- Prior Voice Acting Experience: Harington previously voiced Lockhart in the full-cast Audible audio editions of the series, making his transition to the live-action television show a smooth progression.
- Ideal Filming Location: Production takes place locally at Warner Bros. Studios Leavesden in England, enabling Harington to work on a high-profile production while staying close to his family and two young children.
When Is HBO's Harry Potter Season 2 Filming and Launching?
Principal photography for Harry Potter Season 2 is currently underway at Warner Bros. Studios Leavesden. The overarching production strategy dedicates each television season to a single book in the literary saga.
- Season 1 Premiere: December 25, 2026 on HBO and Max (covering Harry Potter and the Philosopher's Stone).
- Season 2 Expected Release: Late 2027 (adapting Harry Potter and the Chamber of Secrets).
While Harington kept specific details regarding Lockhart's visual appearance and wardrobe top secret, he confirmed that active pre-production discussions and fitting tests are moving forward smoothly. When asked about his personal Hogwarts house allegiance, the actor proudly declared himself a Gryffindor.
