After the show ended, there was going to be a spinoff show called "What's Stevie Thinking?" It was to follow Lizzie's friend's, Miranda, family as they move to Australia to work at a zoo, and the main character would be Miranda's little sister named Stevie. During the early development stages of the show, Selena Gomez was cast as Stevie and even did some screen tests (which you can see online). Unfortunately, the show never saw the light of day.
The broadcast version Lizzie McGuire: Gordo's Video (2002), is different than the DVD version for some regions. In the original version, Gordo not only distorts Miranda's voice for the final cut of his film, but also distorts everyone else's and blurs out their faces, including Kate and Claire. Most of the students watching the film look very amused. In the DVD version however, Gordo only distorts Miranda's voice but shows the faces and uses the original voices of the kids he filmed. The students watching look embarrassed and upset.
