Word on the street is that we might have our new Professor Snape and Professor McGonagall! Talented actor Paapa Essiedu known for "Gangs of London" and "I May Destroy You" is reportedly finalizing a deal to play the complex and brooding Severus Snape. And get this Oscar nominee Janet McTeer of "Ozark" and "The Crown" fame is in negotiations to portray the stern but fair Minerva McGonagall.
These are massive roles to fill following in the footsteps of the late Alan Rickman and Dame Maggie Smith. But Essiedu and McTeer are both seriously talented actors who could bring their own amazing takes to these beloved characters. Fans are already buzzing about these potential casting choices and the internet is definitely having opinions especially about a non-white actor potentially playing Snape which is sparking some debate - surprise surprise!
This news comes hot on the heels of John Lithgow confirming he's set to play Albus Dumbledore. So it looks like the adult cast is coming together with some serious acting power.
Open Casting for Harry Potter Ron and Hermione - Could We See a Brand New Trio?

While the professors are getting sorted what about the golden trio? casting is officially underway for Harry Ron and Hermione. And listen to this they are looking for actors between 9 and 11 years old in April 2025. That is young just like Daniel Radcliffe Rupert Grint and Emma Watson were when they started the movies.
It sounds like HBO Max is really aiming for a fresh start and wants to find a new generation to bring these characters to life for a whole new decade of magic. The casting call also emphasizes "inclusive diverse casting" which is great to hear. Imagine thousands of kids auditioning right now dreaming of becoming the next Harry Potter. It's a big deal!
2026 or 2027: Mark Your Calendars for the Harry Potter TV Series Release Window

Patience Potter fans. We still have a bit of a wait. While filming is set to begin in Summer 2025 at Leavesden Studios (the same place the movies were filmed!) the series is not expected to hit HBO Max until 2026 or even early 2027. These things take time especially when you are building a magical world from scratch.
But think of it this way that just gives us more time to speculate about casting re-read the books and get even more hyped for this new adaptation. HBO Max is reportedly throwing serious money at this project aiming for a "House of the Dragon" level of production quality. So expect some seriously spectacular visuals when it finally arrives.
Faithful Adaptation or Fresh Take? What to Expect from the HBO Max Harry Potter Series

HBO Max is promising a "faithful adaptation" of all seven Harry Potter books. That means each season could potentially cover one book allowing for way more detail and storylines from the novels to be explored compared to the movies. Remember how much stuff got left out of the films? This series could change that.
Showrunner Francesca Gardiner known for her work on "Succession" and director Mark Mylod also from "Succession" are leading the charge. Chris Columbus who directed the first two Harry Potter movies is even giving the reboot his blessing calling it a "spectacular idea." And of course J.K. Rowling herself is involved as an executive producer to ensure the series stays true to her vision while expanding on the story in exciting new ways for TV.
Will Original Movie Stars Return? Don't Hold Your Breath (But Never Say Never!)

Everyone is wondering will any of the original movie stars like Daniel Radcliffe Emma Watson or Rupert Grint make a cameo? Well don't count on it at least not as their main characters. Daniel Radcliffe has said he thinks it's best for the new series to have a "clean break" and that he won't be seeking a cameo. He is excited to watch it as a fan though.
Gary Oldman (Sirius Black) has said he would be open to returning maybe even as Dumbledore! And Jason Isaacs (Lucius Malfoy) joked about wanting to come back as Hermione Granger. Never say never in the world of Hollywood and especially with multiverse storylines being all the rage. But for now it seems like HBO Max is focused on launching a brand new version of Harry Potter for a new generation.
