Production

Development

The Sisters Grimm author Michael Buckley originally conceived the concept for the book series as a pitch for a TV series, but decided to turn it into a book series instead at the encouragement of his friends. Following the books' success, Buckley received offers to adapt the books into a TV series, which he rejected due to the ideas suggesting changes he felt missed the books' "heart and soul". He ultimately agreed to adapt the series after meeting Amy Higgins, who he felt understood the source material. [3]

A series based on the Sisters Grimm book series was first announced to be in development in May 2023. [4] In August 2025, Amy Higgins was announced as the series' showrunner and executive producer alongside Buckley. Additional executive producers include Elliot Blake, Philip Alberstat, Steven Amato, Theresa Park, Chris Prynoski, Shannon Prynoski, Ben Kalina, and Antonio Canobbio, while Sage Cotugno serves s supervising director. Titmouse, Inc. was also announced as the series' production company. [2] Erika Rothchild originally developed the series, before being replaced by Higgins during production; Rothchild received a co-developer credit in the series. [5] [2]

In September 2025, Buckley said it was possible for the series to get renewed for a second season. [6]

Writing

In addition to executive-producing the series, Buckley serves as a writer alongside Higgins and story editor Todd Casey. [6] [3] Buckley said the series includes departures from the book that were decided according to what the writers' room felt were the best ideas for the series. [7]

Higgins said she wanted the series to have an optimistic message, havimg started development shortly after the COVID-19 pandemic, with the series' main theme being that "you can help make your own story" as a reflection of that. [3] The first season adapts the book series' first entry, The Fairy-tale Detectives. [7]

Casting

In August 2025, the series' main cast was announced, with Ariel Winter and Leah Newman cast as the titular sisters, and Abubakar Salim, Billy Harris, and Harry Trevaldwyn starring in additional main roles. [2]

Animation

The series' animation was produced by Titmouse, Inc, which made use of the Toon Boom software for the series; production for each episode of the series lasted over a year. [3] Higgins wanted the animation to have a "storybook quality" throught its use of colors and lighting, while also wanting characters such as Prince Charming to look like regular persons that expressed "these very human emotions". [2]

Release

The Sisters Grimm was released on Apple TV+ on October 3, 2025. [1]
