🎬 New Cast, New Era

While original stars Daniel Radcliffe, Emma Watson, and Rupert Grint won’t return in lead roles, the torch has officially been passed to a new generation of actors.

In April 2025, six cast members were announced:

• John Lithgow as Albus Dumbledore
• Nick Frost as Rubeus Hagrid
• Janet McTeer as Minerva McGonagall
• Paapa Essiedu as Severus Snape
• Paul Whitehouse as Argus Filch
• Luke Thallon as Quirinus Quirrell

🎤 What Do the OG Cast Members Think?

Both Daniel Radcliffe and Rupert Grint have expressed support for the reboot, though they don’t plan to appear in it.

“It would be very weird for me to show up,” Radcliffe told Access Hollywood. “I think the Potter books were always meant to be bigger than one version or one actor.”

Grint echoed a similar sentiment:

“It’s hard to let go… but it would be nice to pass the baton,” he told GQ UK.

Meanwhile, Ralph Fiennes (Voldemort) is open to reprising his dark lord role:

“Sure, of course,” he told Variety. “No question about it.”

🏰 What to Expect from the Reboot

According to HBO’s official statement, the reboot will dive deeper into the original stories, giving each season room to explore the characters and events that were often trimmed down in the films. While the original film series remains available on Max, the new show aims to reintroduce the magical world to both diehard fans and new viewers.

“Harry Potter is a cultural phenomenon,” said HBO chief Casey Bloys. “It’s clear there’s an enduring love for the Wizarding World, and this is an opportunity to revisit Hogwarts in a whole new way.”
