Latest Additions to the Hogwarts Faculty
According to a report from Deadline, Janet McTeer is in discussions to fill the shoes of Professor Minerva McGonagall, while Paapa Essiedu is close to finalizing his contract to portray Severus Snape. HBO has refrained from commenting on these casting developments, stating that they will only disclose information as official deals are confirmed:
We appreciate that such a high-profile series will draw a lot of rumor and speculation.[…] As we make our way through pre-production, we will only confirm details as we finalize deals.

McTeer is a highly talented actress who has demonstrated her prowess on both the big and small screens. She received her first Academy Award nomination for Best Actress in 1999 for her role in Tumbleweeds, which also earned her a Golden Globe win. She followed that with a nomination for Best Supporting Actress in 2011 for her performance in Albert Nobbs. On television, McTeer showcased her skills as Clementine Churchill in HBO’s Into the Storm, earning an Emmy nomination for her groundbreaking performance, along with notable appearances in series such as Netflix’s Ozark and Jessica Jones. Essiedu, too, has established himself as a remarkable talent, garnering an Emmy nomination for his compelling portrayal of Kwame in HBO’s I May Destroy You. He has also participated in prominent projects, including Gangs of London, The Lazarus Project, and a memorable episode of Black Mirror titled “Demon 79.”
For devoted fans of the Harry Potter franchise, the inclusion of these esteemed actors as Professors McGonagall and Snape is sure to instill excitement. Together with Albus Dumbledore, these two characters hold significant roles within the Hogwarts staff. McGonagall, expertly portrayed by the late Maggie Smith in the eight films, serves as Deputy Headmistress, teaches Transfiguration, and oversees Gryffindor House. Meanwhile, Snape, the enigmatic potions master, is portrayed as a complex character with a deep-seated history intertwined with Harry Potter’s parents, leading to initial conflicts with the young wizard’s journey. Both of their storylines undergo profound transformations following [Spoiler Alert] Dumbledore’s death.
While there is some skepticism regarding the Harry Potter television adaptation, especially given the previous film series’ acclaimed legacy and the involvement of the contentious J. K.Rowling, it is clear that HBO is assembling a strong cast for these critical roles. Ultimately, the series’ success may hinge on the choice of actors to portray the beloved trio of Harry, Ron, and Hermione.
The anticipated HBO Harry Potter television series is set to premiere on Max in 2026 or 2027.
