Visible crew/equipment: When Ace is fighting in the "Circle of Death" the little guy picks him up and throws him over his shoulder.When he lands in the dirt you can see a rectangle shape under him flex, complete with tiny dust clouds rising up, from the air being expelled from the mat.
Continuity mistake: When Ace is solving the case in front of the guy that hired him, the guy is playing chess with no-one at all. Then Ace takes big steps towards him, moves a piece, then when the camera cuts back to the guy playing chess, all the chess pieces are gone, no sign of them whatsoever. Then they reappear later.
Continuity mistake: When Ace is singing Chitty Chitty Bang Bang, the windshield of the Jeep is cracked. In the next scene, it's in one piece.
Continuity mistake: Towards the end of the movie, the consul is talking to Greenwall and pours himself a glass of alcohol. The camera zooms out and you see the bottle of alcohol is only 1/4 filled on the table. Then Ace rides in on the elephant along with other animals. A couple of seconds later one of the animals knocks the bottle of alcohol over and you can see it's now almost completely full.
Continuity mistake: Towards the end of the movie, when the consulate general is escaping with the bat, he drives off in one of the vehicles located off to the right, in front of the house. Ace chases him in the monster truck, which was also located on the right. However, when they flash to the shot where the consulate general notices Ace is following him, they show Ace approaching from the left of the shot, and not the right where the other vehicles are still parked in the background.
Continuity mistake: When Ace spits on the Wachatti Chief, they all come out of the hut covered in snot. But, when the camera pans back to Ace he is completely clean while the others are still covered, although he was covered when he came out of the hut.
Visible crew/equipment: When Ace and Greenwall are headed to the Chancellor's for the first time in the Jeep, you can clearly see the stuntman instead of Carrey, when the car is airborne and in a slow motion action shot.
Continuity mistake: When Ace is shooting off his blowpipe at the tribesman balancing on the totem at night, you can see there's nothing coming out the pipe's other end when he blows.
Continuity mistake: After Ace says "I think I lost 'em" while running from the dart blowers, four darts hit him in the back, but in the next shot when he exclaims "Heeeeyyyy." there are five darts in his back.
Visible crew/equipment: When the Jeep is flipping, in one shot, the door flies open and reveals that Ace is wearing jeans. Ace doesn't wear jeans throughout the whole movie showing that this is a stunt double. When the car falls in the parking spot, Greenwall seen through the door is very obviously a dummy.
Continuity mistake: When Ace and Greenwall are driving towards the consulate, just after Ace says 'Now if I can just find a parking spot' he flips the Jeep. From the shot inside Ace turns the wheels sharply to the right, in the shot of the Jeep outside the wheels turn sharply to the left before it flips.

Furthermore, the one he is wearing on the raft got torn earlier in the film after he was hit with the tranquiliser darts, but has been miraculously repaired.
Continuity mistake: Toward the end of the movie, the consul guy is running from the tribes for stealing the bat and he has a rip on his right shoulder. But in the next scene when he turns around to see the gorilla, the rip has vanished. In this same scene, when the ape opens it's mouth, you can see a shining piece of unpainted metal.
Factual error: When Gadji hears Ace imitating a gorilla, he says 'Silverback'. In the next scene he says to Mick 'Female'. A silverback is the dominant male in a gorilla group, named for his coloring. See http://www.wwfus.org/gorillas/species.cfm.
Continuity mistake: When Ace first spots the raccoon on the ledge the shot of the raccoon pacing shows no other ledges to the lower right of the stranded animal. However, when Ace rescues the raccoon we see that the anchored rope is up and just left of the ledge Ace is on.
