Visible crew/equipment: When Melissa dodges the truck that has fallen from sky and Dusty rushes to open a door and help Melissa get out of the truck, the reflection of a camera is seen in the bottom right corner of the truck window. As they move out and pan to the right, you can see a reflection of the same camera and cameraman at the bottom right corner of the truck door as they move away. (00:33:50)
Continuity mistake: Arnold goes to the gay bar to solicit the help of the guy he saved at the beginning of the movie. The guy is wearing a white shirt and a vest black/gold lamay. During their conversation he takes off the vest, then it cuts to another bartender. When it cuts back the guy has the vest on, another shot and the vest is off again. (00:08:05 - 01:10:50)
Plot hole: After the kidnappers kill the trooper and then one chases after the 2 eyewitnesses you can see that they are on a straight road (no turns and he catches up to them fairly quickly) but the next morning when Marge arrives on the scene of the 2 bodies she arrives from the direction of the trooper's body (the first shooting). After examining the bodies of the eyewitnesses she asks her deputy "where the trooper is" and the Deputy points in the direction she just came from and states "down the road a bit" how did she miss it? She would have had to have driven right past the trooper's crime scene to get to the 2 bodies.
Deliberate mistake: In the towel-dance scene after Demi has put on her white panties and spins off the towel from her hair she starts to rip off her body towel. Then in the next frame the towel is again tucked in. Apparently they didn't want Demi topless when she leaned over to slip on her blue shorts.
Factual error: The actual Tsavo lions responsible for the killings had no manes - see for yourself; they are on display at the Field Museum in Chicago. [The filmmakers employed artistic license in using maned lions. They were also certain to include -- at the very end of the movie -- footage of the real Tsavo maneaters, as they appear in the Field Museum.]
Continuity mistake: When Jack is in his new classroom for the first time, he sits at a metal desk. He falls with the desk when he tries to reach his book bag, which is sitting next to a broken wooden desk. Next, he sits in the same - miraculously whole - wooden desk, then proceeds to break it to smithereens.
Visible crew/equipment: After Keanu finds Dr. Alistair Barkley dead on the lab floor and goes to attempt to revive him several shots show nobody else is around him, but straight after he starts to push on his chest a crew member can be seen stood over his right shoulder in a red top with a blue sleeve.levi247
Continuity mistake: Jamie steals a gay magazine at a newsagent. Before he pinches a copy, there are three copies on the shelves. When he pinches it the number of copies on the shelf indeed changes from three into two, but when he leaves the shop, lo and behold, there are three copies on the shelf again. (00:42:15)
Continuity mistake: Towards the end, Danny Aiello fires at James Spader, and we see a brief close-up of the door frame being hit - there are two bullet holes seen in the door - one above and just to the left of the other. Then we cut away, and when we cut back and see James Spader looking around the door frame, there's just one bullet hole.
