Janet McTeer’s Journey from The Menu to Hogwarts: A Familiar Duel with Darkness
The wizarding world is back on screen, but this time, it’s in the form of a fresh Harry Potter TV adaptation. And one cast member, in particular, seems more than ready for the magic and mayhem—British actress Janet McTeer. With decades of award-winning performances under her belt and even a brush with “Voldemort” in another chilling setting, McTeer’s casting as Professor Minerva McGonagall brings both gravitas and curiosity to the project.
Let’s dive into what makes her an inspired choice, her previous run-in with darkness, and the buzz surrounding this magical revival.
A Powerful New McGonagall Steps Into the Spotlight
Janet McTeer, 63, is no stranger to commanding roles. With a career spanning film, television, entertainment and stage, she’s played everything from queens to crusaders. In the upcoming HBO Max adaptation of J.K. Rowling’s Harry Potter series, she’ll be taking on the role of Professor Minerva McGonagall—the head of Gryffindor House and a beloved character previously immortalized by Dame Maggie Smith.
Following in Smith’s footsteps is no small feat. But if there’s anyone with the presence and poise to do it justice, it’s McTeer. Known for her blend of sharp intellect and deep emotional resonance, her portrayal is expected to bring new depth to a character fans already revere.
A Cast with Serious Star Power—and Some New Surprises

Janet McTeer isn’t the only star bringing magic to life in the upcoming Harry Potter TV series. The spellbinding ensemble cast also includes:
• Nick Frost stepping into the shoes of everyone’s favorite gentle giant, Rubeus Hagrid
• Paapa Essiedu portraying the morally grey and deeply layered Severus Snape
• John Lithgow embracing the role of the wise and eccentric Albus Dumbledore
As for the iconic trio—Harry, Hermione, and Ron—their casting remains a closely guarded secret. But with more than 30,000 children vying for the parts, it’s clear the Boy Who Lived is still inspiring a generation. And when it comes to the Dark Lord, speculation is wild—Oscar-winner Cillian Murphy is currently the fan-favorite to don the chilling persona of Voldemort.
Facing Down Fiennes: Janet McTeer’s Eerie Foreshadowing
Interestingly, this isn’t McTeer’s first time encountering a Voldemort-like figure. In the critically acclaimed 2022 satire The Menu, she played Lillian Bloom, an icy food critic who ends up face-to-face with a different kind of monster—Ralph Fiennes’ menacing chef, Julian Slowik.
The plot? A group of elite guests are invited to a mysterious private island for an exclusive dining experience. But the evening soon spirals into terror, as Slowik reveals he has no intention of letting anyone leave alive. Sound familiar? Although it isn’t magic, the evil force is clearly present.
McTeer’s performance opposite Fiennes (who famously portrayed Voldemort in the Harry Potter films) was intense, layered, and unflinchingly bold—much like what’s expected of her in the halls of Hogwarts.
What Critics and Fans Said About the Menu
Critics hailed The Menu as a sinisterly smart masterpiece that slices into themes of artistic pride, revenge, and psychological tension—all served with chilling visuals and razor-sharp wit. Online reviews paint a vivid picture:

• Brie Prescott praised it as “a stunning blend of dark comedy, thrills, and unexpected turns… truly unforgettable.”
• Luis called it “a haunting cinematic triumph… not just a film, but an emotional and visual symphony.”
• Kara B described it as “brilliantly bizarre, deeply clever, and shockingly easy to digest—one of my all-time favorites.”
These powerful endorsements spotlight Janet McTeer’s incredible range, proving she can command both a nightmarish dinner party and a spellbound classroom with equal finesse. From gourmet horror to wizarding halls, she brings undeniable presence to the screen.
Behind the Curtain: The Rowling Controversy
While anticipation for the series is palpable, it hasn’t been without turbulence. J.K. Rowling’s controversial views on transgender rights have sparked waves of backlash, with many fans calling for a boycott of the show. Rowling has consistently denied accusations of transphobia, but her statements have divided the Harry Potter community.
Several members of the original cast, including Daniel Radcliffe and Emma Watson, have publicly distanced themselves from her views. Others, like Ralph Fiennes and Miriam Margolyes, have defended her right to express her opinions.
This divide adds a layer of complexity to the show’s rollout. Will the magic be enough to transcend the controversy? Time will tell.
A New Era for a Beloved Franchise
This Harry Potter TV reboot is more than just a rehash of an already iconic series—it’s a reimagining with the opportunity to explore the books more deeply. Character arcs can develop gradually thanks to the longer structure, which also gives room for in-depth backstories, nuanced details, and obscure subplots.
Janet McTeer, with her formidable experience and a previous eerie encounter with “Voldemort,” is poised to bring McGonagall to life in a way we haven’t seen before. The casting choices, bold and unconventional, signal a new chapter that could either revitalize the franchise or risk alienating its base.
Conclusion: Magic, Mystery, and the McTeer Factor
The casting of Janet McTeer as Professor McGonagall isn’t just about nostalgia—it’s about evolution. She brings gravitas, complexity, and an edge honed by roles like Lillian Bloom. As the Harry Potter series steps into a new dimension, one thing is certain: with McTeer in the castle, Hogwarts is in powerful hands.
Whether the reboot will charm or polarize remains to be seen, but one thing’s for sure—it’s already got everyone talking.
