In November, The Hollywood Reporter and The Wrap cited sources saying Disney is developing the third Princess Diaries film, though Hathaway hasn’t yet signed on.

Hathaway, who was at the festival in promotion of her latest project Eileen, has been tied to the potential next chapter in the Princess Diaries franchise for a few years now.

Before the release of 2016’s Mother’s Day, director Garry Marshall told PEOPLE that he and the actress had been discussing another run at the movie, where she would once again take the role of Mia Thermopolis. Marshall died in July 2016.

“It looks like we want to do Princess Diaries 3 in Manhattan,” Marshall told PEOPLE before his death. “Anne Hathaway is very pregnant, so we have to wait until she has the 𝑏𝑎𝑏𝑦 and then I think we’re going to do it.”

Marshall also explained at the time that Chris Pine reprising his role from Princess Diaries 2: Royal Engagement also wasn’t entirely out of the question. Royal Engagement, which marked Pine’s film debut, premiered in 2004.

One name that appears unlikely to return for the film is Julie Andrews, who told Access Hollywood in December that transforming into Queen Clarisse Renaldi once more may be a long shot.
