HBO has finalized its choice of two actors to portray key characters in the upcoming “Harry Potter” series, based on the beloved literary source material. Reports indicate that Janet McTeer, known for her role in “Ozark,” is in talks to take on the role of Professor Minerva McGonagall. Additionally, it has been revealed that Emmy-nominated actor Paapa Essiedu, one of the first actors selected for the series, is signing on to play Professor Severus Snape.

They are set to join John Lithgow, who, as previously reported, will portray Professor Albus Dumbledore. HBO, as is its custom, has declined to comment. “We understand that a project of this magnitude will generate a lot of rumors and speculation,” the network stated. “As pre-production progresses, we will only confirm details once agreements are finalized.”

The Harry Potter series, planned to span over a decade, is expected to adapt each book into a separate season. Notably, the HBO series continues to expand the Harry Potter franchise, fostering a more “inclusive and racially diverse universe.“
