Update — Arabella Stanton says she has “just started filming” Hermione Granger for HBO’s Harry Potter TV reboot, while Audible’s new Harry Potter: The Full‑Cast Audio Editions launch on November 4 with a monthly rollout through May 2026.

What’s new in the Harry Potter TV series and audiobooks

Stanton, 11, confirmed the TV production milestone in an Associated Press studio interview with her audiobook co‑stars Frankie Treadaway and Max Lester: “I can’t say much, because they’ve cast a Mimblewimble tongue‑tying spell on me,” she said, “but I’ve just started filming, and it’s great at the moment.” She added, “I think when I was 8, I started reading the first one… I’ve loved Harry Potter. I love it.”

The AP visit also captured frank, funny moments about snacks (“The chocolate fridge is dedicated to chocolate.”) and craft. Stanton said, “I love books. I love writing, I love reading… And I think books [are] the main connection between Hermione and I.” She’s eager to hear “all the spells,” and singled out the Time Turner and Invisibility Cloak as favorite magical objects.

Why the dual casting matters

Stanton’s “double duty” consolidates character continuity between screen and audio at a moment when a new generation is meeting Hermione through two formats at once. Her comments about spellwork, books, and the Time Turner echo classic Hermione traits and suggest a grounded, studious take that aligns with the character’s canon.

Context, quotes & notes

  • Stanton on secrecy: “Mimblewimble tongue‑tying spell… I’ve just started filming.”
  • Stanton on kinship with Hermione: “I love books. I love writing, I love reading… books [are] the main connection between Hermione and I.”
  • Snack‑time levity from the studio: “The chocolate fridge is dedicated to chocolate.”
  • Bill Nighy on returning as a different role: “I was pleased to be asked to play the professor after having already played a Minister for Magic… I’m hoping to be a significant part of something that will keep children entertained…”
  • David Holmes on his ‘full circle’ moment as Stan Shunpike, recalling stunt‑doubling inside the Knight Bus.

Bottom line for fans searching for the new Harry Potter series

If you’re looking for the new Harry Potter series on TV, the HBO Harry Potter reboot is actively filming for a 2027 debut. If you want something sooner, the new Harry Potter series in audio arrives on November 4, led by a full cast and monthly releases. The Harry Potter TV series and the new audiobooks share one key thread: Arabella Stanton’s Hermione.
