J.K. Rowling, who disliked Daniel Radcliffe’s casting, would likely oppose HBO's decision to hire Paapa Essiedu as Snape in the Harry Potter reboot.

The casting of Paapa Essiedu as Snape has set off controversies from many different sides of Harry Potter fandom, or even outside of that, for multiple reasons.

The Harry Potter HBO series is in negotiations with Janet McTeer to play Minerva McGonagall and Paap Essiedu is near a deal to play Severus Snape.

And there’s more! A new cast will fill the old roles made famous by the likes of Daniel Radcliffe, Rupert Grint, Emma Watson, and Co. There aren’t many details about the series available just yet, but here’s a quick breakdown of what we do know so far.

HBO is close to finalizing two more key cast members for its highly anticipated adaptation of the Harry Potter series. Oscar and Emmy-nominated actress Janet McTeer is in talks to take on the role of Professor Minerva McGonagall and Paapa Essiedu in talks as well.
