Visible crew/equipment: Towards the end of the film you see the long haired baddie grab Milo by the hind legs (just before Milo puts the mask on). As Milo starts to change you can just about see the baddie who is holding his legs, except he is now a different person with brown curly hair, nobody who is seen prior or following this shot. Presumably he is the dog trainer. (01:23:15)
Continuity mistake: When Ace is sneaking into Ronald Camp's Private Aquarium, he begins to look around and open some doors. If you look at the colour of the wall it is red. When he opens the door to the giant tank, the wall outside the door (which should be red) is now white. The door also reverses - the handle goes from Ace's left to Ace's right. (00:28:50)
Continuity mistake: After Inspector Todd is shot, Axel chases after De Wald and fires at the truck. When the guy at the back of the truck is shooting at Axel, we see multiple bullet holes near the truck's back right window, but in his close-ups the bullet holes are gone. The window frame's scratched paint differs as well in the close-ups. We know it's the same window because we also see him in the shot of the truck's interior.Super Grover
Deliberate mistake: In the scene where the bad guy is attached to the missile and fired, in the split second before it hits the helicopter you can see below it a building called SUN BANK, but the letters are backwards. A close look reveals the likely reason - to the right of the reversed building is one which looks just like the building to the LEFT of the Sun Bank building behind the harrier a few seconds earlier. Most likely they couldn't film the chopper from the right side because there was a building there (the one the camera flies through), so they filmed it from the other side (the same side they'd filmed the harrier from), catching the "Sun Bank" behind, then had to flip it to have everything facing the right way. (02:06:55)
Continuity mistake: When the cops first pull up beside the BMW and Jack pulls a gun out to shoot the cop with the shotgun, he hits a bump and blows the cop car's tire, causing it to flip. They show it flip behind the BMW, but the other 2 cop cars (on the passenger side and behind the BMW) have disappeared. (00:27:25)Jason Sieberg
Continuity mistake: During the car chase scene near the end of the movie when Connors jumps on to the black car the windshield is only slightly lowered. Later during the chase the gap is much bigger and when we see Callahan struggling in the back seat it's lowered all the way down. Also, Connors grip on the car keeps changing between closeups and far off shots.
Continuity mistake: In the opening rodeo sequence, Pepper's horse is brown in the chute, but black on the close-ups out in the arena. (00:01:25)
