19. Speaking of the film, The Lizzie McGuire Movie became a surprise hit when it was released in May 2003, debuting at No. 2 at the box office behind X2: X-Men United, going on to gross over $50 million.
20. Many fans were upset that Miranda was not in the movie and was M.I.A. in some of the last episodes of the show, with her family going on an extended vacation, but that was actually because Lalaine wanted to focus on her music career.
21. After becoming a teen idol thanks to her time as Lizzie, many were surprised when Duff chose to take a break from acting, a decision she opened up about in a 2015 interview with PrideSource.
"Everyone thought I was just absolutely nuts because I was really successful and making a lot of money. And it was scary, because there was no guarantee that my career was still gonna be there," she said. "I really needed it personally. I grew up in the spotlight and on tour and with everyone just knowing me and knowing me a certain way. At some point I was like, 'I don't even know if I'm that person anymore, and I don't even have the time to figure that out.'"
She admitted that she found being known as Lizzie "torturous" at times, explaining, "I loved it during the filming. I just didn't know what a success the show was gonna be, and after that...I was still Lizzie McGuire to people and that was super annoying. Now it's not. I don't care now."
