Continuity: At the end of the movie where Inspector Gadget gives an award to Penny he puts it around her neck and when the camera faces her, her hair is in the ribbon and when they show her back it is out of the ribbon and then repeats itself about 3 times.

Continuity: In the scene where Penny is strapped to the cart, Inspector Gadget frees her and they both run away from the cart. The cart then explodes and Inspector Gadget is propelled forward. The Gadgetmobile pulls up and Inspector Gadget lands on the bonnet from a position directly above, which would be impossible if he was going forward.

Other: When Claw steals a whole bunch of gold, there seems to be a lot in there. First: How did he get so much gold in there with so little time? They seemed to have been throwing around the gold coins and stuff not to have enough time to do that. Second: Later in the movie you get an above look while they are trying to escape Inspector Gadget, there is less gold in the truck than there was earlier.

Revealing: When they freeze time towards the end, we see a boy jump into a pool and then the splash is in mid air. If you look closely at one point you can see him move a little underwater.

Continuity: In the scene on the bridge where Claw's Ice Cream Truck is coming toward Inspector Gadget, G2, Penny, and the Gadget mobile, the first shot shows the truck not far away. It is driving toward them, but takes a long time to get there. The truck takes about 15 or 20 seconds to reach them, although it should have taken less than five, according to the first shot.

Plot hole: Why did Inspector Gadget put his glove on his right hand? We see a toilet brush in place of his hand with a glove on it, yet when he's flying through the air doused in toilet water, he has his glove back on.
