Visible crew/equipment: In the "Battle of Carthage" in the Colosseum, one of the chariots is turned over. Once the dust settles you can see a gas cylinder in the back of the chariot. (01:22:55)
Visible crew/equipment: When Émilien is chasing after the Ninjas on foot, they jump from a bridge onto the top of an orange lorry. The orange crash mats that the 'Ninjas' land on are visible in the overhead shots. (00:47:35)
Continuity mistake: When the girls figure out that Knox is after Charlie, and Dylan thinks of the picture and they zoom in onto "Townsend." The shot before the final shot of the photograph shows Knox's father's arm around Charlie, when in all the other shots, he has his arms above his head. (01:00:05)
Other mistake: When Big Momma is taking a shower, you can clearly see that the shower head is a mirror, with the water coming only out of the top, and when Big Momma bends over, you can also see her reflection in the shower head. (00:12:00)
Continuity mistake: The tyres on the crotch rocket motorcycles they were riding kept changing from knobbly tyres to road slicks, back and forth depending on what terrain they were on. Easiest to see when Ethan skids on the road to avoid the white van - clear shot of slick tyres - then about 30 seconds later they're on the dirt, he skids into the old car and you can easily see that he's got off-road tyres front and back.
Continuity mistake: When young Magneto is struggling with the guards at the concentration camp, the father's star switches from one side of his chest to the other. (00:01:46)
Continuity mistake: When Memphis is driving Eleanor he backs up and hits the right rear-view mirror. He stops, leans out the window and sees that it is dangling. The very next shot it is back to normal and it stays that way for most of the rest of the movie. (01:34:34)
Factual error: When Arnold is in the police station reporting that he has a clone and passes through a control room, one computer screen is flashing "OVERIDE." The correct spelling is "OVERRIDE." (00:38:05)
Visible crew/equipment: When Wesley is in the interrogation room with the 2 way mirror, as the camera pans around the room the reflection of the camera and the crane it's mounted on, and even a crew member, are all perfectly visible in the mirror. (00:33:25)
Continuity mistake: Before Sidney pulls the killer out of the door on the house set, we see the bedside table is lengthwise against the wall. As the killer falls towards the bed it's turns 90 degrees, so the bed is a bit closer to the door. (01:05:45)
Continuity mistake: After Johns dies and Riddick is talking to Fry you see in one shot that only the bottle that Fry is holding is lit up, yet in the very next shot you see that all three, Fry, Jack, and the Muslim kid's bottles are lit. (01:23:40)
Continuity mistake: When Spencer says, "Lots of people believe in them, even though they never see them," Molly's bed does not have a headboard, but in the next shot, it does. Also, Molly is looking straight, but in the next shot she is looking towards Spencer. (00:00:27)
Continuity mistake: When we see the police officer checking the hit counter on an adult web site, the hit counter goes down from 1,739,986 to 1,739,944 a few seconds later.
Continuity mistake: When Shuya finds Utsumi dead, the proximity of her head to the girl behind her changes between shots, as does the position of her tie and gun beside her.
Continuity mistake: In the start of the film Matthew McConaughey is sitting on a porch at a wedding reception smoking a cigar, in one shot he has a stub left then in the next it's a new one. (00:12:20)
