Revealing mistake: In the second murder, the killer of the first one is bashed in the head by a monkey wrench, her head split open. A second hit ensues, but there's no reaction to it, no further spraying or damage, the head itself barely moves, and with delay. (00:04:30)
Continuity mistake: When the sniper starts shooting at the audience, at one point he hits a guy in the press sector. However the blood splatter at the victim's shirt appears yet before the bullet actually breaks the window.
Factual error: When a Rear Admiral and Captain are walking together, the Captain's epaulets are the wrong way round. A cardinal sin in the Navy. (01:30:00)
Continuity mistake: The movie opens with a gang of thieves taking the luggage of several Japanese tourists distracted by a guy pretending to defecate on the lawn. One of the robbers is snatching a bright red suitcase in the first shot, which turns into a plain brown suitcase in the next. Also in this second shot one of the bags is lying on the street, while in the previous they were all on the sidewalk. (00:02:40)
Revealing mistake: When the children stay with the tribe, all of the horses being ridden, although shown having a saddle blanket, actually have saddles under those blankets.
Continuity mistake: The protagonist (Renato Pozzetto) is having an argument with his superior while smoking a joint. He gets back in line after threatening him with a stone; the joint is in his mouth. Cut, and he is holding the joint in hand and putting it only then in his mouth. (00:19:00)
Plot hole: Since the criminals who used the dogs to rob the bank in the first movie were never apprehended (No criminal worth their salt would tell the authorities their caper was spoiled because the canines ran off with their loot), there is no way the people who are hunting the dobermans in the beginning of this movie would know the dogs were still carrying the cash. (00:18:00)
Other mistake: Legendary wrestler Antonino Rocca makes a cameo appearance in the movie. He is, as correctly listed in the closing credits, one of the "Funeral Attendants" together with Michael Weil. However in the opening credits he was specifically billed as the Funeral Director, which is Ronald Willoughby's role as correctly listed in the end credits. (00:00:50 - 01:45:15)
Other mistake: On the assault course Hero and Rockbottom are wondering how they are going to get to the concert now that they have lost their van, Rockbottom says that they are well out of the London transport system but when they are on the zip wire you can see two red London transport buses on the road outside.
Revealing mistake: While Funn and Bell are warding off their attackers by throwing Coke cans at them from the machine, Eggs is busy rewinding the retrieved film reel around his body. However, when he's done 'winding', it's obvious the amount of film wrapped around him is significantly less than what was on the film reel.
Continuity mistake: When Christella is slapped by the possessed Ike, her pose changes between shots.
Revealing mistake: By order of the shrewd Harry Webb, the helicopter just destroyed the Cessna on the ground. The two guys decide that they are gonna walk back to civilization. Cut to the vehicle driving to the explosion site, and you can see in the desert sand ahead of the jeep fresh tire tracks from previous takes. And it keeps happening during the desert chase. (00:10:20)
