Dr. Claw's face is never shown throughout the entire course of the film. This is a reference to a running gag from the original Inspector Gadget (1983) TV series. Only his eye is shown for a spilt second.
The film was shot entirely in and around Brisbane, Queensland, Australia.
D.L. Hughley, who voiced Gadget mobile was the only original cast member to return from Inspector Gadget (1999), the previous movie.
Claw's hideout in an abandon Bowl-Rite factory was actually an old sugar factory in Australia.
Every extra was given glasses for the Science Convention scene.
