The announcement of these young actors in May 2025 immediately sent shockwaves across the internet, solidifying the series' commitment to a new vision.

The adult casting has delivered some of the most exciting and unexpected names, bringing a wealth of experience and gravitas to the roles of the Hogwarts staff and other key figures. These choices indicate a serious, high-caliber approach to the dramatic elements of the series.

The New Dumbledore, Snape, and McGonagall

• John Lithgow as Albus Dumbledore: The legendary, two-time Oscar nominee and six-time Emmy winner, John Lithgow, has been cast as the new Albus Dumbledore, Hogwarts' beloved Headmaster. Lithgow, known for his roles in The Crown, 3rd Rock from the Sun, and Dexter, confirmed his casting, stating the role would "define the rest of his career."

Essiedu is celebrated for his breakout role as Kwame in Michaela Coel's drama series I May Destroy You, as well as roles in Gangs of London and The Lazarus Project. His theater background, including being the first black actor to play Hamlet at the RSC, suggests a fiercely intense and layered Severus Snape.
• Janet McTeer as Minerva McGonagall: The formidable Deputy Headmistress and Head of Gryffindor will be played by two-time Oscar nominee Janet McTeer.

Casting the Malfoys and the Ministry

• Johnny Flynn as Lucius Malfoy: The patriarch of the Malfoy family and a Death Eater, Lucius Malfoy, will be played by Johnny Flynn.
