The Disney Channel show Lizzie McGuire was so successful that Walt Disney Pictures turned it into a feature film, The Lizzie McGuire Movie, which hit theaters May 2, 2003.
Asked about the milestone anniversary, star Hilary Duff told The Hollywood Reporter: “Oh my gosh. Has it been 15 years? Don’t tell me that!”
The movie follows a group of soon-to-be high schoolers who travel to Rome with their new principal, Ms. Ungermeyer. When the class visits the Trevi Fountain, an Italian pop star named Paolo mistakes Lizzie (Duff) for his singing partner and ex-girlfriend, Isabella. When Paolo finds out that Isabella left Italy when they broke up, he asks Lizzie to pose as her during the Italian Music Awards and lip-sync a performance. From there, a series of adventures ensue until (spoiler alert!) Lizzie and friends get their happy ending.
“That was a hard shoot,” Duff said. “We were in Italy for a portion of it and no one spoke English. The crew would go and drink wine in the afternoon and then come back to work and no one would finish the work day. It was insane! It was so different than filming the show in America.”
Duff also reminisced about her favorite part of filming.
“It was really fun to be on the catwalk and change clothes a bunch of times and be in a bubble-wrap dress,” she added. “The back of the Vespa was a really important moment for me.”
The series, which premiered in 2001, went on to air new episodes through 2004. Read on to see what the cast has been up to in the years since.
