Development , pictured in 2009, serves as the program's central focus during its two-season run. In 2000, Hilary Duff was asked to audition for a series on Disney Channel. Created by
Terri Minsky, the series was known by the working title ''What's Lizzie Thinking?
throughout development. The series was later retitled Lizzie McGuire'', and Duff successfully auditioned for the title character of Lizzie, who was described as a regular teenager. Producer
Stan Rogow conceived a
high-concept version of the script in which an animated version of the character would be featured to convey these thoughts. This concept became known the "animated Lizzie" persona, and was also voiced by Duff. Rather than drawing a mere caricature of Duff, she tried to capture the actress's essence by giving Lizzie's alter ego a more "hip" look: cropped shirts with trim pants and high flip-flops. The drawings were
digitally inked and painted using the
Animo 3.1 software and then composited into the live-action footage at Disney's
Los Angeles studio. According to Ashley Spencer's 2024 book ''Disney High: The Untold Story of the Rise and Fall of Disney Channel's Tween Empire'', Lalaine and Duff had a "falling-out (that was) beyond repair" in the final stretch of filming of the television series, which led to her being let go early from her contract. "I don't believe that Hilary wanted her to be part of the movie,"
Lizzie McGuire casting director Robin Lippin said. "It probably would have been uncomfortable for both of them." Filming of the movie and series concluded in December 2002 after 65 episodes were produced, a standard limit for Disney Channel's series. After the series ended its original run, Disney Channel also considered producing an animated version of the series. In November 2004, a pilot for an intended spin-off was ordered, which was to center on Miranda's younger sister Stevie Sanchez and her Latino family. Lalaine returned to film the pilot, after having been released from her
Lizzie McGuire contract six episodes early due to feuding with Duff. The new series would follow the 12-year-old central character, who was played in the pilot by
Selena Gomez, and would also feature an animated version of the character like Lizzie. The pilot was described as a "real downer." On August 23, 2019, it was announced at the
D23 Expo that
Disney was developing a revival television series of
Lizzie McGuire. The series was revealed to be in production for exclusive distribution on the
Disney+ streaming service, with Duff reprising her role as the title character; the original series creator, Terri Minsky, planned to serve as the revival's showrunner. When Lizzie discovers her fiancé cheating on her, she returns home to
Los Angeles. The animated alter ego of Lizzie would also have appeared in the series. It was later announced that Lamberg would be reprising his role as Gordo and Federico Dordei would be joining the cast as new character Dominic Shaw. Further filming for the series would have taken place in
Los Angeles. Minsky departed as the showrunner of the revival in January 2020 after the first two episodes of the series had been filmed, due to creative differences with Disney. Production of the series was placed on a hiatus. In February 2020, Duff hinted on social media that production had stopped because the series was not thought "family-friendly" enough by Disney+ executives; Disney reaffirmed that the development of the series was ongoing. In April 2020, it was reported in that development was still ongoing, however, in December 2020, Duff announced that the revival was officially canceled. In January 2024, one of the show's writers revealed some of the storylines from the show, and also speculated that Disney had issues with the suggestion that Lizzie had sex with her childhood love interest Ethan. ==Release==
