It’s time to visit Genovia once again, as Variety is reporting a third Princess Diaries movie is in the works.
As of now, franchise star Anne Hathaway isn’t signed on to the project and it isn’t known if she will. However, she has expressed interest in returning to the character of Mia Thermopolis over the years, as has co-star Disney Julie Andrews, who played Queen Clarisse Renaldi.
Plot details haven’t been confirmed, but the threequel is expected to continue the story in the first two Princess Diaries films rather than rebooting the series. A few years back talks of a Disney+ spinoff were planned and centered around Mia’s half-sister. It is unknown if this new film will pull from the now-canceled spinoff.
Aadrita Mukerji (Reacher, Supergirl) is currently writing The Princess Diaries 3. My guess is like Hocus Pocus 2 and Disenchanted, this film will be exclusive to Disney+, but that has yet to be confirmed at this time. Sadly the original Director Garry Marshall passed away a few years ago so the search for a new director to tackle the project is underway.
