Everything We Know About The Princess Diaries 3
Shut up! We have more details about The Princess Diaries 3, and our teenage selves are screaming. When it comes to comfort movies, The Princess Diaries is at the top of the list. Following Mia Thermopolis (Anne Hathaway), as a secret princess who gets called to Genovia by her royal grandmother, Queen Clarisse Renaldi (Julie Andrews), it has provided our generation with quotable moments and, of course, the big makeover scene — which is recreated on TikTok constantly. While the movie has been in development since 2022, the biggest casting announcements were made in 2026. And yes, that includes whether or not Chris Pine will be back as Nicholas Devereaux. Below, we’ve rounded up everything we know about The Princess Diaries 3, including the cast, plot, trailer and other details from the creatives. Which original cast members will return for The Princess Diaries 3? In 2024, Anne Hathaway shared the Princess Diaries 3 announcement on Instagram and seemed to confirm she will be back as Mia. “Miracles happen. Back to Genovia with [director] Adele Lim. The fairy tale continues,” she said. In 2020, Julie Andrews said she would be “up for” returning as Queen Clarisse Renaldi on The Talk, saying she would love to work with Anne again. However, in 2022, Andrews changed her tune. “I think it would be too late to do it now. There was talk of a sequel many, many years ago,” she told The Hollywood Reporter. “It’s too far down the line now to go back to it. It’s a lovely thought, but I don’t think it would probably be possible.” This doesn’t completely rule Andrews out, but it looks unlikely. However, there are some other key cast members returning. During a BookCon panel, author Meg Cabot revealed that both Robert Schwartzman, who played Michael Moscovitz, and Chris Pine, as Nicholas Deveraux, were both in the script. “There’s a part for everybody, because there’s a thing that happens where everyone has to show up. Robert Schwartzman’s in it. Chris Pine obviously is in it. Although he says he’s not, but he is,” Cabot teased. What is the plot of The Princess Diaries 3? In August 2025, director Adele Lim shared an open casting call for The Princess Diaries 3, which gave fans some clues about the potential plot. The studio was seeking an actor to play a 15-year-old character named Olivia Robinson. Fans of the book series instantly connected this to The Princess Diaries, Volume XI: Royal Wedding, where Mia discovers half-sister Olivia, from a secret affair between Olivia’s mother and Mia’s father, Phillipe. After Olivia’s mother passes away, Mia tries to gain custody after hearing her half-sister is being mistreated by other family members. What has Anne Hathaway said about The Princess Diaries 3? On April 20, 2026, Anne Hathaway confirmed The Princess Diaries 3 was still in the works. During an interview with EW, she noted that The Devil Wears Prada 2 took over unexpectedly. “We’re constantly working on [The Princess Diaries 3],” she said. “The intention is to make Princess Diaries hopefully next [although a third film] is not greenlit or confirmed yet.” Hathaway and her team have been “chipping away at the script” because everybody seems to want the film. “If I learned anything from [Devil Wears Prada 2], it’s that expectations are very, very high, and if you’re going to do it, you have to knock it out of the park,” she added. When will The Princess Diaries 3 be released? The Princess Diaries 3 hasn’t been filmed yet, as Hathaway has been so busy. During BookCon, Cabot said, “I don’t know when they’re going to film it, because Anne Hathaway, as you’ve probably seen, is making a million movies right now.” “One of these days she’s going to go to the castle that we have actually rented and is sitting there waiting… movie number three, it’s going to be amazing.” We’re going to have to sit tight and wait a little longer before we see any more mattress sliding antics. Is there a trailer for The Princess Diaries 3? Not yet, the film hasn’t been made.
