Series Release Date: What We Know
HBO's commitment to a ten-year run ensures that each book will receive its own season, with expanded storytelling and character development not seen in the original films. Warner Bros. Discovery is leaning heavily on the franchise to bolster HBO Max, betting that a new generation of viewers—and lifelong fans—will be eager to return to Hogwarts.
The series is expected to premiere in 2027, according to Warner Bros. Whether it lives up to its towering expectations remains to be seen, but one thing is certain: the sorting hat has spoken.

A Star-Studded Hogwarts Faculty
HBO's take on the wizarding school includes an acclaimed lineup of stage and screen veterans—some reinterpreting familiar characters, others embodying them in entirely new ways.
John Lithgow as Albus Dumbledore
The Emmy- and Tony-winning U.S. actor, known for his roles in Terms of Endearment and Conclave will join the cast as the headmaster of Hogwarts School of Witchcraft and Wizardry, and all-powerful wizard.
Lithgow, 79, has described the opportunity as "a defining moment for the final act of [his] career." He follows in the footsteps of the late, great Sir Michael Gambon, who replaced the equally great Richard Harris in the film series following Harris' death in 2002.
Janet McTeer as Minerva McGonagall
McTeer will star as McGonagall, one of the franchise's most beloved characters. She is Hogwarts' stern transfiguration professor, but also the head of Gryffindor House and deputy headmistress under Dumbledore.
McTeer is known for her roles in Ozark and Tumbleweeds and has previously received both Oscar and Emmy nominations. She will be filling the shoes of the late Dame Maggie Smith, who portrayed the iconic witch in seven out of the eight original films.
Paapa Essiedu as Severus Snape
Essiedu is known for his roles in Michaela Coel's I May Destroy You and the series Gangs of London. He has received critical acclaim for his work in theatre and became the first Black actor to play Hamlet in the Royal Shakespeare Company back in 2016. He takes on the role of Hogwarts' enigmatic potions master and head of Slytherin House.
Nick Frost as Rubeus Hagrid
Nick Frost will be taking up the role of the half-giant groundskeeper at Hogwarts. Frost is best known for his performances in Edgar Wright's so-called Cornetto Trilogy of films, which include Shaun of the Dead and Hot Fuzz.
Nick Frost arrives at the Universal Pictures Presents Los Angeles Premiere Of DreamWorks "How To Train Your Dragon" on June 7 (L). The first look at Frost as Hagrid in the new 'Harry Potter' TV...

The legendary comedian brings his BAFTA-winning experience to the role of Hogwarts' grim caretaker.
Longtime fans of the franchise may know that Whitehouse has been in the franchise before, playing Sir Cadagon in the third film, though his scenes were deleted and he was relegated to a background character in the theatrical cut.
Louise Brealey as Rolanda Hooch
Brealey will be flying into the role of Hogwarts' sharp-eyed Quidditch instructor. The English actress is known for her portrayal of pathologist Molly Hooper in the acclaimed BBC series Sherlock, as well as for roles in Back and A Discovery of Witches.

The role was originally played by Julie Walters in the film series.
Johnny Flynn as Lucius Malfoy
Fresh off his stage role as Richard Burton, Flynn embodies the cold elegance of Draco's pure-blood father, originally played by Jason Isaacs, who said of Flynn's casting: "A fantastic actor, a lovely man and, irritatingly, a rather brilliant musician too. Couldn't have handed the snake-topped baton on to anyone better. Just please don't make him sing..."
