Star Needed for ‘The Princess Diaries 3’

Author Meg Cabot told attendees at BookCon 2026 in New York City that filming for the next Princess Diaries sequel has not begun. She blamed the delay largely on Anne Hathaway’s packed schedule.

Production status

The project was first announced as in development in 2022. Disney continues to develop the film with producers and writers attached.

Adele Lim is set to direct. The movie is planned as a direct sequel to The Princess Diaries 2, not a reboot.

Filming location ready

Cabot said a castle location has already been rented for production. The site is reportedly prepared for shooting in Toronto.

She also expressed gratitude to fans who have supported Genovia. Cabot said she looks forward to attending the premiere when it happens.

Casting and crew

Anne Hathaway is expected to return as Mia Thermopolis, though some confirmations remain pending. Her availability is central to casting plans.

Chris Pine and Mandy Moore have signalled interest in reprising their roles. Julie Andrews has not publicly confirmed her participation.

Scheduling challenges

Hathaway’s 2026 slate includes multiple high-profile projects. Titles reported for that year are Mother Mary, The Devil Wears Prada 2, The Odyssey, Flowervale Street, and Verity.

Those commitments have complicated efforts to set production dates. Coordinating calendars remains the main hurdle.

Outlook and fan reaction

Cabot described progress as slow but steady behind the scenes. Fans remain enthusiastic about a new installment.

Talk of a Star Needed continues, since Hathaway’s timetable will largely determine when Princess Diaries 3 can move forward. Filmogaz.com will monitor developments and report updates as they emerge.
