HBO Confirms Seven Hogwarts Professors for New Harry Potter Reboot

Overview

• Reporting on Monday, July 27, 2026, named seven confirmed professors for HBO’s reboot of J.K. Rowling’s books rather than a continuation of the film timeline.
• John Lithgow is reported to play Albus Dumbledore, Janet McTeer is reported as Minerva McGonagall, Paapa Essiedu is reported as Severus Snape, Luke Thallon is reported as Quirinus Quirrell, Louise Brealey is reported as Madam Hooch, and Sirine Saba is reported as Pomona Sprout.
• Warwick Davis is the only confirmed actor from the original films to return, reprising Professor Filius Flitwick while six other faculty roles are being recast with new performers.
• Coverage highlights that recasting high-profile professors invites close audience comparison to the original movies while the TV format gives HBO more time to expand classroom scenes and supporting characters.
