The Princess Diaries 3 Moving Forward, Says Producer Debra Martin Chase

Development continues on The Princess Diaries 3, with producer Debra Martin Chase offering fresh insight into the project's trajectory. The franchise installment has been in active development since 2022, when it was first officially announced.

Speaking to People magazine this month, Chase—who has produced both previous films in the series—expressed optimism about the film's path forward. "We are more than hopeful," she stated. "We are moving in that direction. We've done a lot of groundwork."

The producer acknowledged that initial timelines have shifted. "We had hoped to be shooting this year," Chase explained. "So, it's coming. We're intent upon making it happen. And we're excited that the people are excited. Every time something happens and we get the thing, it's like, 'Yay, okay, keep going!'"

Adele Lim, known for helming Crazy Rich Asians, has been brought on to direct the third installment.

What's the Story?

Based on casting notices that emerged last summer, the film will draw from Meg Cabot's 2015 novel "The Princess Diaries, Volume XI: Royal Wedding." The story introduces a new character named Olivia Robinson, described as a 15-year-old of mixed race who is intelligent and guarded, using sharp humor to protect deeper emotional wounds following personal loss.

The plot centers on Olivia being Mia Thermopolis' previously unknown half-sister, born from a secret relationship involving her father, Prince Philippe. After discovering Olivia's existence and learning she's been mistreated while in the care of extended family members, Mia takes her in. The narrative unfolds as Mia—who is expecting twins and preparing for her own royal wedding—becomes embroiled in a custody battle on Olivia's behalf.
