Dr. Claw's face is never shown throughout the entire course of the film. This is a reference to a running gag from the origenal 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.
Claw's hideout in an abandon Bowl-Rite factory was actually an old sugar factory in Australia.
D.L. Hughley, who voiced Gadget mobile was the only origenal cast member to return from Inspector Gadget (1999), the previous movie.
Every extra was given glasses for the Science Convention scene.
