Plot hole: On arrival at the Summerland castle the Polar Bear King becomes human during the midnight hour (as part of the spell) and performs his husbandly duties with his carry-on wife. Why did he not become human during the journey from Winterland to Summerland which took several days? (00:32:40)
Plot hole: When Frank gets the phone call that Bobby has been shot, all that is said is that Bobby has been shot on the street in Italian. They never said Richie shot him.
Plot hole: The helmet design is rubbish. The eyeholes are far too small - that close to the eyes the divider between the eyeholes would block almost a third of the wearer's vision. He would hardly be able to see what was right in front of him - and it is not too close nor too narrow to fall into the "blind spot" between the eyes. This is not a character error by Peevey - the helmet design came from the original plans - it is even shown in the German propaganda film!
Plot hole: When Toby is checking everyone to make sure their costumes work, wheelchair-bound Bud is shown standing in a coffin-fixture. Since he was in the coffin costume, there was nothing there to be "holding" the character in a standing position, and he was obviously not in his wheelchair, as he is at standing height with everyone else.
Plot hole: Cady's plan to get revenge on Bowden includes raping and assaulting Lori. This part of the plan, however, hinges on Lori not reporting Cady to the police, which he had no way of knowing that she wouldn't. If she reported him, the investigation would have created huge problems for Cady. He bit off a chunk of her face, so the wound could have been matched to his teeth, as well the chunk of skin he bit off and spit out most likely would have had traces of his saliva on it. Not to mention evidence that could have been gathered from a rape kit and eyewitnesses that could have placed Cady at the bar with Lori beforehand (the bartender, for example). In all likelihood, he would have been arrested, tried and convicted. Lucky for him, Lori was too ashamed to report the incident.
Plot hole: The Bishop in the film is performing the duties you would expect of someone in his position (giving mass, hearing confessions, performing weddings etc.) He has his own private chambers in the cathedral, refers to Robin as 'the boy I knew' and talks about hearing his Father's confession four months earlier; so he's been around for a while. The problem is the credits refer to him as the 'Bishop of Hereford'. No explanation is ever given for why the Bishop of a city 100 miles away is living and working in Nottingham rather than looking after his own diocese; or why the Bishop of Nottingham isn't around to look after his. (The Bishop of Hereford was an enemy of Robin Hood in the original ballads, and it's likely the filmmakers just gave that name to the Bishop in the film due to its familiarity, without thinking about the plot hole this creates).
Plot hole: At the bar shootout where everyone except Marlboro and Harley are murdered, the two jump through the window, over the fence, into the airport, and into an airplane luggage compartment. They would have been caught by security. The missing, and dead, airport worker would have been missed and searched for, the gunfire would have attracted attention, and the police would have been called. They never would have left the airport.
Plot hole: When the police chief asks Joe 'where's the briefcase they were telling me about?' Joe tells him to look in the back seat of the white BMW. There are a couple of problems with this. First, the police chief is looking for a case with a bomb in it, because he received a phone call from the guy who had his BMW stolen. Even if he knew about the money, which is unlikely, the police chief has no way of knowing that the case he is about to open is not a bomb, since no-one saw Marcone steal the case with the bomb in it. Yet he opens it without calling the bomb squad. Second, Joe saw Jimmy put the case with the bomb in the back seat, so why doesn't he warn the police chief about it? (01:35:00)
Plot hole: No amusement park ride company would ever produce a prop scythe that was as sharp as depicted in the movie.
Plot hole: Laura moves to Iowa and rents a nice, large house, conveniently furnished with everything she could possibly need, by using a fake name, having no job, no established financial history, has no current bank account or credit cards, or any references. She merely hands cash to the agent to seal the deal. She later lands a job without proof of identity, citizenship (legally required), and has no references, no credible work history, or a different social security number. Laura is resourceful, but certainly lacked the illegal avenues to obtain a convincing fake identity and other false documentation. If she had been able to do any of that, then it would have to be incorporated into the plot as credible exposition. Movies audiences are sometimes expected to employ a "suspension of disbelief" for the sake of the plot, but this stretches credulity.
Plot hole: When Clarice visits Lecter in his new makeshift cell, she brings his drawings, which were left behind in Baltimore. She tells him how she saw the lambs being killed and heard them screaming, taking one lamb with her when she ran away. As the guards approached his cell after she leaves, the camera pans across the cell, taking in the drawings Clarice had brought, and the top one is a very detailed drawing of Clarice holding a spring lamb. She only told just told Lecter about the lamb, not enough time for him to have done that drawing.
Plot hole: When Torch, Blade and Leech Woman go to the farmer and his wife's house while they are asleep, they killed both the farmer and his wife. The wife was consumed by flames, but not the farmer. When Torch and Blade returned to the Puppet Master with the brains, the Puppet Master says the brains are burnt up. The farmer's brain would not have been burnt up, only his wife. (00:31:50 - 00:37:50)
Plot hole: Splinter knew all along the name of the company who made the Ooze, and literally sat on this vital piece of information for over a decade just because he was too stupid to simply look the name of the company up, written on giant letters and far from being hidden - he merely had to open the yellow pages, no doubt. Nobody with such a telling piece of evidence about their own origins (the canister that mutated them is in his hands and has the logo of the company with the name spelled out) would be unable to find out something this obvious. (00:22:00)
Plot hole: The famous line "There can be only one" is uttered in every Highlander film. At the end of the original, Connor obtained the prize by killing the Kurgan and being the last one. However, in this film and others, you find out that there are still others around, such as Duncan, the woman who was Duncan's girlfriend in Endgame, the other immortals following Jacob in Endgame, and the ones that showed up in The Source. So, why did Connor obtain the prize? He still wasn't the last one.
Plot hole: After Cali's father is killed the decision is made to cut power to the school so he or his men don't find out about his father. But if power was cut to the school then what is powering all the machinery in the kitchen that's providing food for 90 students?
