Mia Thermopolis will always be one of our favorite princesses.

It’s hard to believe that it’s been almost 20 years since The Princess Diaries first hit the big screen. The family-friendly Disney film sparked a sequel and a large part of the cast is still raving about the special project. Case in point: in May Anne Hathaway honored the director of the film Garry Marshall in an ABC special.

“One of the things I love about Garry is that he was never afraid of the spontaneous moment,” Anne shared during the Happy Days of Garry Marshall. “If it was good, it was in the movie. He didn’t care where it came from, he didn’t care what happened.”

In fact, Anne described a scene with Lilly Moscovitz (Heather Matarazzo) that didn’t exactly follow the script. The actress “never” thought about the scene until it appeared in the film’s trailer six months later. As she recalled, “he kept it because it was a charming moment.”
