When Claw's hearse-limo pulls up to the bluff overlooking Riverton Harbor, we see the driver reach across the dashboard and switch off the ignition key, but the sound of the car's engine had already stopped a second or two earlier.
When you see the truck at the warehouse, there is no wall between the front and back and the truck is loaded full of standard gold bars in stacks, and several sacks of coins. However, when you see the overhead view of the truck as the rocket ship emerges, there is a wall between the front and back, there are no sacks, the gold bars are much smaller, and the stacks of bars occupy much less of the space than before.
A standard gold bar weighs about 27 pounds, and the amount of gold loaded into the ice cream truck would have overloaded the truck. It would have also caused problems from shifting during the high speed pursuit.
When Dr. Claw uses his weapon, time freezes all over the city of Riverton, showing several actions stopping in mid-motion and remaining in position. This means that the electronic devices in the building of the federal reserve - the gate, retina scan and the vault door - should be inoperable and impossible to function.
Claw and his minions break into the Federal Reserve and they have not even started loading the truck. the next shot shows Gadget and G2 racing towards the bank. but before they arrive, Claw and his minions seem to be stuffing around with the gold and not putting it in the truck. But there the truck is clearly fully loaded with gold when Gadget & G2 arrive. How did they get all the gold in the truck in that little amount of time?
This movie was dedicated to partially hiding Claw's face, mainly from the eyes up. However, there are 2 instances where they accidentally fail at this. The first is when Claw is at his Bowlrite lair. As he exclaims that they will build a super weapon, the light reflecting off his claw shines on his face thus removing the shadows & exposing him right before he begins to explain his plan.
This occurs again when the Gadget and G2 arrive at the Reserve. When Claw dragged Penny towards the Ice Cream Truck and calls for Brick & McKibble, the camera goes too low and accidentally shows us a good side-view glimpse of his face.
This one occurs near the end, when McKibble is about to run Gadget over with the ice cream truck. In a close-up on the front left wheel, you can see it's spinning backwards as if in reverse even though they are moving forward. This is corrected in later scenes.
