Plot hole: The whole concept of a kidnapper 'pretending' his victim didn't get on the plane in the first place is utterly laughable. Even if nobody saw her in her seat, why didn't they see her walking down the aisle to her seat, or waiting to board the plane, or in the boarding tunnel itself? Why isn't she listed on the passenger manifest, or on her mother's travel documents or airline ticket? And there would have been security cameras all over the airport.
Plot hole: Toward the end of the movie, it is revealed that Silvia spent the night in the secure room where the Matabo President was taken after the assassination attempt so that she could be alone with him and threaten to kill him. With the U.N. and Secret Service on alert for an assassination attempt, wouldn't they have swept the secure room right before the Matabo President arrived that day? In addition, Silvia would have had to use her access card to get in that area of the building, so there would be a record of her being in the building but not at her station. Wouldn't that raise some suspicion long before Tobin figures it out?
Plot hole: Near the end, when Ice asks to say goodbye to the kids in the hotel room, the kids have on their pajamas, yet their luggage was left on the train earlier in the day. It is unlikely that they would have gone to the train station to get their belongings following the chaos of the Christmas party.
Plot hole: At the beginning, it shows Santiago crossing the border into the U.S. But the U.S. border patrol is on the Mexican side.
Plot hole: In the course of the story it's said that at the time the black hole went out of control, it had a mass of "half a mountaintop of granite." But in a flashback scene Dr. Krone is shown growing the mass of the hole by feeding it large numbers of lead bricks in the laboratory. It's a little hard to believe his lab could store, or even afford, enough lead bricks to equal that much mass.
Plot hole: The Hellworld website at the beginning of the film has eerie music and also Pinhead's voice reciting some of his famous lines from other Hellraiser movies, which is impossible; there's no way that someone could have gotten recordings of those moments in the past where he said the lines, so they couldn't be playing on an internet webpage.
Plot hole: In the end of the movie, when Willy Wonka decides to visit his father, his father does not recognize him until he looks at his "rare teeth." But the wall of newspaper printings that Charlie was looking at included a recent enough picture of Willy that the father would have definitely recognized him, before seeing his teeth, as Willy doesn't look like a normal person with that outfit.
Plot hole: About two thirds of the way into the film, Gina comes running into Montebello's to talk to Joe, while Joe bursts into Prestolani's to confront Gina. Of course, in typical romantic comedy fashion, they just miss each other. However, the two pizzerias are directly next to each other, and both characters were using the front doors. Therefore, there is no way that they could possibly have missed each other.
Plot hole: The movie takes place before and around 1938 and, supposedly ends in that year, following the entrance in Shanghai of the Japanese, with the exodus by many Chinese and foreign residents. Ralph Fiennes' character, as an American ex-diplomat and businessman, would have resided, have bank accounts, his car, etcetera, in the foreign concessions. The Japanese did not occupy the concessions until after Pearl Harbor, so there was no need for him to flee the city, as a refugee without a passport and with little or no money, sailing towards Macao in a fragile Chinese junk. He could just have driven or walked a few blocks to any of the "Western" concessions, from where he could have married Natasha Richardson's character, obtained U.S. passports (White Russians had none, as the rest of her family in the movie until assisted by an official in the French Consulate) for her and her daughter, purchased a ticket in a safer vessel, sold his assets (regardless of the damage to his club, he still had a house, furniture, a car, presumably bank accounts, etc.).
Plot hole: After the bird is hurt, Jimmy is shot several times and wounded very badly. Yet just seconds later, he is able to save the young boy, and mysteriously use many of his "crow powers" despite being hurt very badly.
Plot hole: There is no way Dirk, Al, and Eva could have made it from the top of the fort to their camels, raced cross the desert and then hid themselves in the sand all before the train were to have met them. The train was barely visible when Dirk saw it through the scope which means it was much farther away to begin with.
Plot hole: The survivors find their way to the internet lounge to send out a message via email about the terrorist attack. The ship was upside down. All satellite dishes used to transmit over the internet were completely submerged in water. Even if there was power to the computers, they would not have been able to get a server connection let alone send out email.
Plot hole: When the group first finds the plane, they are all able to hold their breath long enough to descend, search the plane and resurface. Yet later in the movie, even though Amanda can get a full breath of air from the air pocket in the plane, she can't hold her breath long enough to swim to the surface and has to be rescued by Jared.
Plot hole: In the opening text scroll, it is said that the creatures live in the dark, and the name of the movie is "Alone in the Dark". But at the very end (when Edward and Aline are walking around the deserted city), the camera zooms in on the couple suddenly, implied they were attacked by one of the monsters, but in broad daylight.
Plot hole: During the end of the fight scene in the hotel, Charlie gets hold of Dexter's gun. This gun is a Desert Eagle variant that fires either a .357, .44, or a .50AE caliber round. At the close proximity to Laroche that Charlie was, he would have taken his head clean off his shoulders instead of just taking out his eye.
Plot hole: The entourage of scammers travel about the city at will. One of the group is an internet junkie who always has his laptop in hand and turned on. No matter where they go, in their car, in an old warehouse, etc., they always have an uninterrupted wireless internet connection.
Plot hole: Tyler jumps into the water, then grabs his mask and puts it on and begins swimming, but he fails to clear his mask by blowing the water out of it. Without clearing it, he wouldn't have been able to see a thing.
