“Lizzie McGuire” did not end its run due to poor ratings back in the early 2000s. The show was at its peak, particularly following the success of “The Lizzie McGuire Movie.” But in an interview with Entertainment Weekly, Hilary Duff’s mom/manager, Susan Duff, explained that the show ended due to Hilary’s financial disagreements with Disney.
Susan explained that Disney ended negotiations for a sequel to the movie when she asked that Hilary be paid an immediate bonus. She also claims Disney was trying to only offer her daughter $35,000 per episode for continuing the series, even though she claims outside parties were offering her six figures. It was that experience that halted the future of “Lizzie McGuire” indefinitely. And even when Duff tried to return to make a reboot the way the original cast and crew imagined it, it was again shut down after the company and the stars couldn’t see eye-to-eye.
