Previous from December 4, 2024:
Itâs reported that the Harry Potter TV series is eyeing Paapa Essiedu to play Severus Snape, the fan-favorite character from the books and movies.
Severus Snape was played by the late Alan Rickman in the popular films.
The info comes from THR that adds if Paapa Essiedu gets the role, âit will also be an example of HBO following through on its promise that the series would have a diverse cast.â The site points out that the Harry Potter movies âhave been criticized for having an entirely white core castâ and the casting âwill presumably lead to a rather fresh take on the character.â
HBO wouldnât confirm the casting and only commented on the rumor: âWe 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.â
Paapa Essiedu is known for I May Destroy You, The Lazurus Project, Gangs of London, and The Capture.
THR also says Mark Rylance is up to play Headmaster Albus Dumbledore, and that Cillian Murphy playing Voldemort isnât happening. Deadline also says Mark Strong is in contention to play Dumbledore.
