In 2017, Mandy Moore, known for her role in The Princess Diaries and her 1999 bubblegum pop hit Candy, appeared to still appreciate relics of her past, despite transitioning to more mature projects and avoiding a public meltdown, as she was often seen sporting bows.

16 years earlier, she played Lana Thomas, the popular rival of Anne Hathaway’s character in the 2001 American coming-of-age comedy film, The Princess Diaries, which was based on Meg Cabot’s novel and grossed over $165 million worldwide.

The Princess Diaries movie was released on August 3, 2001. At that time, Mandy Moore was 17 years old. Principal photography took place from September to December 2000 when she was 16 years old.

She later appeared in other Disney productions, including the 2006 American animated direct-to-video musical fantasy comedy-drama film Brother Bear 2 and the 2010 American 3D computer-animated musical adventure fantasy comedy film Tangled.

Dan Fogelman, who wrote the screenplay for Tangled, later got her an audition for the 2016 drama series This Is Us.

On the 15th anniversary of the release of The Princess Diaries in 2016, Mandy Moore reflected on her first major movie role as the high school cheerleader nemesis, Lana Thomas, and her experience working with the late director Garry Marshall, who passed away on July 19, 2016.

“I think in the light of the world just losing Garry Marshall, it’s an especially poignant moment,” said Moore. “I feel incredibly lucky that I got to work with him, and so lucky that it was my first-ever job.”

“He had no business casting me,” she added. “I was 16, I’d never done a movie before, and I didn’t know what I was doing. So I think the highlight of the film was working with him. He was the first director I worked with, and he was the loveliest. He was like everyone’s grandpa–he had so much patience and was hilarious and made everybody laugh.”

“Obviously, he’d been working with the same crew for decades, so everybody knew and loved him,” she said. “He was so wonderful, kind, and patient with all of the actors and the extras. Being around him was fantastic–his energy really set the tone.”

“I think being part of a film with a bunch of other people my age and never having done it before–kind of dipping my toe into this experience–it really set the ball in motion for me,” she said. “I was like, ‘Oh, yeah, this movie stuff is fun. It’s like going to summer camp with all of your friends.’ It was a remarkable experience.”
