Nicholas Hoult cast as professor in HBO’s highly anticipated Harry Potter season 2
icholas Hoult will play Gilderoy Lockhart in the second season of HBO’s “Harry Potter” TV series, according to reporting from Variety.

Hoult is also known for his roles in films like “Mad Max: Fury Road,” “Nosferatu,” “Juror #2,” “The Menu,” and “Renfield.”
TL;DR
- Nicholas Hoult cast as Gilderoy Lockhart in HBO’s “Harry Potter and the Chamber of Secrets” season 2
- Hoult earned both an Emmy nomination and two Golden Globe nominations for his role in Hulu’s “The Great”
- Filming on the second season is due to begin this fall
- The second season is expected to air in late 2027
The casting makes headlines on both sides of the Atlantic
The Superman star has been tapped as a high-profile cast addition to the upcoming second season of HBO’s Harry Potter series. This marks a homecoming for the British performer: at 17, he played Tony Stonem in the British series Skins (2007–2008), a breakout role that launched him to wider recognition. Hoult is represented by UTA, 42, and Sloane Offer.
The casting arrives fresh off Nicholas Hoult’s acclaim in the Superman universe. He played Lex Luthor in the movie, one of the biggest villains in the D.C. universe. His ability to pivot between prestige television and blockbuster franchises makes him an ideal fit for a character that demands both comedy and menace.
How does Lockhart compare to Branagh’s interpretation?
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. Hoult’s Gilderoy Lockhart is a notoriously vain, boastful and fame-obsessed wizard well versed in Memory Charms who is recruited by Dumbledore as Professor of Defence Against the Dark Arts at Hogwarts.
He becomes the new Defense Against the Dark Arts teacher at Hogwarts, but it quickly becomes evident he is not qualified for the job. Kenneth Branagh previously played the character in 2002’s Harry Potter and the Chamber of Secrets. Branagh’s film version leaned into theatrical foppishness; Hoult’s take may explore deeper layers of insecurity beneath the charm.
The HBO series brings star power to Hogwarts
The highly-anticipated series is due to debut on December 25 on HBO and HBO Max, with the first season adapting the first book in the novel series, “Harry Potter and the Philosopher’s Stone.” The show will launch globally on HBO Max on Christmas Day 2026, including recent launch markets Germany, Italy, and the UK & Ireland. The show has already been renewed for a second season, which will be based on “Harry Potter and the Chamber of Secrets.”
The ensemble cast continues to expand impressively. Additional cast members include:
- John Lithgow as Hogwarts headmaster Dumbledore
- Janet McTeer as Professor McGonagall
- Paapa Essiedu as Severus Snape
- Nick Frost as Rubeus Hagrid
- Dominic McLaughlin as Harry Potter
- Arabella Stanton as Hermione Granger
- Alastair Stout as Ron Weasley
What’s next for production?
Filming on the second season of “Harry Potter” is due to begin this fall. This aggressive timeline means the second season could reach audiences by late 2027, keeping momentum strong after the holiday premiere of season one. Given Lockhart’s prominence in “Chamber of Secrets,” Hoult’s performance will be central to whether this ambitious HBO adaptation captures the book’s darker tone.
