Factual error: When the Titanic sinks all six dwarves and Kevin end up in the sea clutching a lifebelt. The water in which the Titanic sank was freezing - that is how most of the casualties died, by freezing, not drowning. In water like that you'd be lucky to stay conscious for more than a few minutes. Despite this none of them show the slightest effect of the cold. Maybe the dwarves have some 'magical' ability to withstand lethal cold, but Kevin doesn't even react to being plunged into freezing cold water. He'd be screaming in pain, but he doesn't even show the slightest sign of discomfort.
Visible crew/equipment: When Wez rips the door off the tanker you can see a crouched crew member next to Max. This has been disputed but it is there, watch underneath the steering wheel just after Wez starts shouting "Go! Go! Go!". (01:19:05)
Continuity mistake: When Snake kills the wrestler he falls forward shoulders forward, next minute his arms are over the ropes, next minute his arms are in a different position again - quite active for a dead man. (01:16:55 - 01:18:10)
Continuity mistake: The name patch on O'Niel's uniform changes between "O'Neil" and "O'Niel".
Continuity mistake: In the head exploding scene the table gets covered in blood and brain matter, but in the next shot the table is clean. (00:13:05)
Factual error: Franklyn Hart keeps his car running by pumping out the gas from the bottom of abandoned gas pumps which the pumps themselves couldn't reach. In reality, as this gas is on the bottom, it would be full of sludge and garbage, and since it has been sitting there for 20 years, it would barely be usable and would probably damage the engine. He certainly wouldn't be able to do high speeds with it.
Factual error: After the autopsy of "Sheila," the medical examiner tells the entomology expert that "she has no internal organs whatsoever." Yet, we're looking at "Sheila," and she has not been cut open at all, certainly not in the standard Y-shaped incision used in autopsies. Wouldn't even the worst medical examiner at least look inside before stating that internal parts were missing?
Continuity mistake: In the scene where the robots run out of battery, the female robot stretches out her right arm and shuts down in that position. The male robot walks up and stretches out his right arm and shuts down holding hands. In between shots of holding right hands, you see them holding left hands. First right hands, then left hands, then right hands again.
Visible crew/equipment: When Anne and Tyler break into the morgue, the shadow of the camera can be seen on the wall outside.
