Will Rupert Grint Be In The New Harry Potter Series? Odds of a Surprise Cameo Explored!

Will Rupert Grint be in the new Harry Potter series? As HBO gears up for its highly anticipated TV adaptation of J.K. Rowling’s magical saga, fans are buzzing with speculation about whether Rupert Grint, the beloved actor who brought Ron Weasley to life in the original Harry Potter films, might make a surprise appearance in a new role.

With a fresh cast of young actors—Dominic McLaughlin as Harry, Arabella Stanton as Hermione, and Alastair Stout as Ron—taking over the iconic trio, the possibility of Grint returning in a different capacity has sparked excitement. Let’s dive into the odds, the context, and the clues surrounding this tantalizing prospect!

Has Rupert Grint Expressed Interest in Returning to the Wizarding World?

Rupert Grint has shared mixed feelings about revisiting the Harry Potter universe. Back in 2021, he told Variety that a continuation featuring the original cast would feel “weird,” but he found the idea of a new group of characters “interesting."

However, in 2023, Grint struck a more open tone, telling Metro UK he’d be keen to reprise his role as Ron Weasley if a new project came around and the timing was right, even suggesting he’d be ready to “pass the baton” for a TV series. This shift hints at a willingness to engage with the franchise again, perhaps in a fresh role rather than as Ron.

Grint’s comments leave room for speculation. While he’s not likely to reclaim his original character—given Alastair Stout’s casting—his openness to revisiting the wizarding world could pave the way for a cameo as a new face, perhaps a quirky shopkeeper, a Hogwarts professor, or a Weasley relative.

What Role Could Rupert Grint Play in the HBO Series?

If Rupert Grint were to appear in HBO’s Harry Potter series, the role would likely be distinct from Ron Weasley. The new series, set to debut in 2026, aims to be a “faithful adaptation” of J.K. Rowling’s seven books, following the journey of a new generation of young actors.

With Alastair Stout stepping into Ron’s shoes, Grint could take on a supporting character—perhaps a member of the Weasley family like Bill or Charlie, or even a completely original role created for the show.

Another possibility? A nod to fans with a brief, nostalgic cameo—think a mysterious wizard in Diagon Alley or a Ministry of Magic official. Grint’s red hair and familiarity with the franchise make him a natural fit for a Weasley-adjacent role, but HBO might opt for something unexpected to keep viewers guessing.

How Likely Is a Cameo Based on Past Cast Comments and HBO’s Approach?

The odds of Rupert Grint appearing hinge on several factors. Daniel Radcliffe, Emma Watson, and Rupert Grint have had a complex relationship with the franchise and J.K. Rowling, particularly after public disagreements over her comments on transgender issues.

Rowling, an executive producer on the HBO series, has said she “couldn’t be happier” with the new cast, but tensions with the original trio might complicate cameo appearances.

That said, HBO’s approach—casting fresh faces like Dominic McLaughlin, Arabella Stanton, and Alastair Stout after auditioning over 30,000 children—suggests a focus on new talent.

Yet, the inclusion of established actors like John Lithgow as Dumbledore and Nick Frost as Hagrid shows room for familiar names in supporting roles. Grint’s 2023 comments about being open to a return boost the odds slightly, but no official confirmation exists as of June 6, 2025.

What Are the Odds of Rupert Grint Appearing in the HBO Series?

Calculating the odds of Rupert Grint’s appearance is speculative, but let’s break it down. His positive 2023 remarks suggest interest, but his earlier hesitation and the new cast reduce the likelihood of a major role.

HBO’s decade-long commitment to the series, starting production in summer 2025 at Warner Bros. Studios Leavesden, offers multiple seasons for potential cameos. Fan demand for nostalgia could also sway producers.

We’d peg the odds at a cautious 25-30%. A cameo isn’t guaranteed, but Grint’s history, his openness to returning, and HBO’s blend of new and veteran talent keep the door ajar. No reports or leaks as of June 6, 2025, confirm his involvement, so it remains a hopeful possibility rather than a certainty.

Why Would a Rupert Grint Cameo Excite Fans?

Fans adored Rupert Grint’s portrayal of Ron Weasley, bringing humor, loyalty, and heart to the films from 2001 to 2011. A cameo in the HBO series would bridge the old and new, offering a nostalgic thrill for longtime viewers.

Whether as a Weasley family member or a fresh character, his presence would spark buzz, boost ratings, and honor the legacy of the original trio alongside newcomers like Stanton, McLaughlin, and Stout.

The question—Will Rupert Grint be in the new Harry Potter series?—lingers, and fans are eager for any hint of his return. With filming on the horizon and a 2026 premiere looming, only time will tell if Grint steps back into the wizarding world.

Could We See Rupert Grint in 2026? Stay Tuned!

Will Rupert Grint be in the new Harry Potter series? The odds of a cameo rest on his cautious enthusiasm, HBO’s vision, and the balance of fresh and familiar faces. While a 25-30% chance feels reasonable, no concrete news confirms his role as of June 6, 2025.

Some Closing Thoughts:

As the HBO series prepares to enchant a new generation, a Grint appearance would be a magical treat for fans.
