Continuity mistake: Ace watches two villains through a metal grate while inside the rhino, but when it shows the rhino from the outside, there is no visible grate. Also, if there were one, light from it should be seen as well as the ray of light coming from the rhino's posterior.
Continuity mistake: When Ace is inside the robotic rhino, the fan stops working. Soon after, when the shot focuses on Ace, he has a strand of hair on his forehead. The next shot it is not there, but in the next shot it is.
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.
Visible crew/equipment: In the scene with the two Australians in the hut when the camera switches to a wider shot as soon as the bald headed guy says, "Disgusting rat!" the boom mic dips into view for a second.
Continuity mistake: When Ace is driving the car (near the beginning), before he turns into the jungle "short cut", they are in clear terrain. When they show him turning, there are tons of trees around.
Continuity mistake: During the Cliffhanger skit at the beginning, the rigging holding the racoon starts to break, at first it shows the stress fracture breaking left to right. When it breaks, it breaks vertically.
Continuity mistake: In the mansion in the scene at the chess table for half the scene the chess pieces are there. The end of the scene, the pieces are gone.
Other mistake: When Ace supposedly wipes the loogies from his eyes you can see his palms are under his eyesockets.
Continuity mistake: When Ace is hit with darts, his shirt falls off his shoulder but in the next shot, it's back on.
Other mistake: When Ace is dancing with the unconscious Monopoly Guy, you see a shot of the woman with the fur scarf near the bottom of the stairs. But, when Ace turns around near the bottom of the stairs, she is not there. It might be hard to see, but she was there, the guy on Ace's shoulders would've hit her.
Other mistake: When the Wachatti chief spits in Ace's face, you can clearly see it goes to the side of his body, thus never hitting his face.
Other mistake: When Ace is singing "Chitty Chitty Bang Bang" in the car, he drives his car through a creek. Then we see a shot of Spike (the monkey) covering his head with a map to keep him from getting wet. In the very next shot we see Greenwall with that same map in his hands.
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.
