Visible crew/equipment: When Alan throws his father's broken radio into the box and he turns around to talk to the girl on the ladder, the reflection of a crew member wearing a white T-shirt can be seen in the monitor on the desk as the camera follows Alan.
Audio problem: When the Commando Elite rip out through the clear plastic 'window' of their packaging, the sound made is that of paper ripping - a different sound to what the plastic being punctured would make.
Continuity mistake: Alan's shop has been robbed and his Dad comes in and sees the mess. A few mins after that when Alan is taking off on his bike with the toy in his bag, Link Static is up in the tree radioing to Chip Hazard telling him he has seen a Gorgonite. When they sling-shot the commander onto the bike further down the road, you can see that Link Static is there pulling back the elastic when he should be up in the tree.
Continuity mistake: When Allen goes to his room, just after his Dad has left, it is dark outside, but just minutes before when he came into the house it was still light.
Continuity mistake: When Brick Bazooka has his legs torn off by Alan's bike gear, he hits the road with only the legs missing; you can see the hip piece attached to his torso. But as he hand-walks to respond to Hazard's call, the hip - which has the radio built in - lies some distance away from him.
Continuity mistake: In the scene where Alan discovers his father's shop ravaged, he writes a "Closed" sign and posts it on the window. Later on the sign he takes off the window is different from the one he puts up.
Visible crew/equipment: When Phil Hartman unveils his new entertainment centre for his wife, the mirrored doors fold elegantly away to give a nice reflection of the film crew.
Factual error: In order to incapacitate the Fimples, the Commandos fire sleeping pills into their drink via a mouse trap converted into a catapult. But in every spring- or torsion-powered one-armed catapult, a horizontal bar is required which stops the arm as it swings forward, or otherwise the load would be smashed into the ground in front of the weapon.
Continuity mistake: When Alan and Joe are unloading the truck, Joe hands Alan the first box. As Joe is talking about his father trusting him, he turns and the camera angle changes to show him putting a box on top of another one. Since this is supposed to be the first box, it should be going on the ground.
Continuity mistake: In the first shots of the toy shop there is an Oktoberfest notice in the window next to the front door. When we next see the shop that evening it is gone. There is a sign in the street implying that Oktoberfest hasn't happened yet so it is unlikely Alan would have taken the sign down.
Continuity mistake: When Alan first slaps onto the front door of the shop the "CLOSED" sign he wrote, the yellow cardboard is high on the glass, above another smaller piece of paper on the corner; then when Christy stops by shortly afterward and knocks on the glass door, the sign is slightly lower, this time covering the top part of that same small piece of paper. This can be seen even more when Alan later removes the sign from the door.
Revealing mistake: When Alan and Christie race their scooter over the ditch (and the Commandos follow suit to their doom), look carefully in slow-motion; the scooter is actually sliding down a wire, like a runaway cable car.
Continuity mistake: When Irwin is looking up the components of the toys a big red "Access Restricted" symbol appears when the details of the X1000 chip are displayed. The camera angle changes to show Irwin talking to Larry; in the background the same screen is showing on the computer but the "Access Restricted" symbol is gone.
Other mistake: When Chip Hazard's chopper is shot down, he jumps clear before it goes down. But he jumps up, and at the height his leap takes him, he should get his head chopped off by the rotors.
