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: 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 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.
Continuity mistake: In the 'circle of death' scene, after the small tribesman has bitten Ace's hand, Ace shouts something about biting. In this shot, he throws off his watch - you have to look very closely to see this. Later in this scene, his watch is back on his wrist, most obvious when he is pointing at 'the do'.
Continuity mistake: At the beginning of the movie, after the monk gives Ace the medallion, we see a front shot of Ace grasping the medallion with his fingers bent around it. The shot then changes to a sort of side shot of Ace and a front shot of the monk. In this shot, we can see that Ace is no longer grasping the medallion, but holding it with his fingers open. When the shot changes back to Ace's front, his fingers are no longer open and he is once again grasping it with his fingers.
Continuity mistake: During the Circle of Death fight, Ace is hit with two spears, one in each leg. When he falls backwards onto the ground, the spear in his right leg remains straight up, while the spear in his left falls flat on the ground. The warrior then walks over, steps on Ace's groin, and yanks out the spears, both sticking straight up in the air.
Continuity mistake: When Ace is tied to the raft, he is wearing a completely different shirt from the one he was wearing in the previous scene. 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.Maxamania
