The Official Casting Announcement
HBO’s Harry Potter has added Nicholas Hoult to its Season 2 cast in a key role — he will play Gilderoy Lockhart in the upcoming season of the series.
HBO Max made the announcement on Instagram, with the post captioned: “Magical Me indeed. Now, how many autographs would you like? Nicholas Hoult has been cast as Gilderoy Lockhart in season two of the new HBO Original Harry Potter Series.”
The news was first reported by Deadline. The casting was confirmed on August 11, 2026 — a significant addition to an already star-studded ensemble that has been growing since the show was first announced.
Who Is Gilderoy Lockhart?
Lockhart is a central character in Chamber of Secrets. As the book begins, he is a famous wizard known for many heroic acts that he has documented in a number of books, though he is also incredibly arrogant and vain. He becomes the new Defense Against the Dark Arts teacher at Hogwarts, but it quickly becomes evident he is not qualified for the job.
Gilderoy Lockhart is a pompous wizard and professor at Hogwarts; he was played by Kenneth Branagh in the second Harry Potter movie, 2002’s Harry Potter and the Chamber of Secrets.
Hoult’s task is considerable — stepping into a role that Kenneth Branagh made iconic over 2 decades ago while making it entirely his own for a new generation of fans.
Why Hoult Fits the Role — A Career Built on Complexity
Nicholas Hoult is no stranger to playing characters who blur the line between charm and menace. The Superman star has been tapped as a high-profile cast addition to the upcoming second season of HBO’s Harry Potter series.
His accolades include nominations for a British Academy Film Award, 2 Golden Globe Awards, and a Primetime Emmy Award.
From 2020 to 2023, Nicholas Hoult starred as Peter Pugachev in the television series The Great, showcasing his talent for dark comedy and satire. That precise combination — dark comedy, vanity, charm turned rotten — is exactly what Lockhart demands from any actor brave enough to take him on.
Hoult was cast as Hank/Beast in the X-Men franchise, starring in X-Men: First Class (2011), X-Men: Days of Future Past (2014), X-Men: Apocalypse (2016) and X-Men: Dark Phoenix (2019).
He also starred as “R” in the romance/horror zombie film Warm Bodies (2013), Jack in Jack the Giant Slayer (2013), and Nux in Mad Max: Fury Road (2015).

Season 1 — What to Expect First
HBO renewed its Harry Potter series for Season 2 in May, with the 8-episode Season 1 — titled Harry Potter and the Philosopher’s Stone — set to debut this Christmas.
In Season 1, “there is nothing special about Harry Potter – at least that’s what his Aunt Petunia always says. On his 11th birthday, a letter of admittance to Hogwarts School of Witchcraft and Wizardry opens up a hidden world for Harry: one of fun, friendship and magic. But with this new adventure comes great risk as Harry is forced to face a dangerous enemy from his past.”
After more than 30,000 children auditioned for the roles, Scottish child actor Dominic McLaughlin was selected to play Harry Potter.

The Bigger Picture
The casting of Nicholas Hoult sends a clear message about the calibre of talent HBO is willing to attract for Season 2. Each season of the HBO show is expected to cover 1 book in author J.K. Rowling’s Harry Potter series.
Lockhart is arguably the most theatrical, most demanding comedic role in the entire Harry Potter universe — a character who must make audiences laugh, cringe and feel sympathy all within the same scene. With 30 years of screen experience, 41 feature films, a BAFTA nomination, 2 Golden Globe nominations, and a proven ability to play complex, layered antiheroes — from Beast to Lex Luthor to Peter III — Hoult arrives as the most qualified actor imaginable to step into Branagh’s legendary shoes.
