Plot hole: There must be a lot of dumb scientists in Sebastian's lab. While defibrillating the invisible gorilla, (s)he becomes completely visible for a moment. However, not once do the scientists consider that applying a mild electrical shock to the system renders the invisible animal visible again - that electricity may be the key to the whole invisibility problem. They don't even comment upon the fact that the gorilla does become visible.
Factual error: Near the end of the film Knox is flying a Huey helicopter and the Angels hitch a ride by shooting it with a spear gun and dangling on the line behind it. Suddenly adding about 200kgs to a Huey in flight like that is going to cause all sorts of problems with the trim and airspeed of the aircraft - the pilot would know immediately that something was wrong.

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.
Factual error: The cavemen Harrier pilots are shown using the hover mode frequently. Harriers, even with drop tanks as depicted in the film, can hover for at most 5-10 minutes, as the thrust required to keep the aircraft in the air without any lift consumes massive amounts of fuel and overheats the engine, and real-life Harrier pilots are instructed never to hover for long periods of time, unless absolutely necessary. The amount of time the cavemen spent hovering (hiding out of sight in a parking garage, sneaking up on the Psychlo gunships, etc.) would have easily caused their fuel to run dry.Dom
Continuity mistake: When Daniel is being chased by the Yakuzi in their black Mitsubishi Lancer Evo 6s, one of their Lancers crashes into the tanks. The car used for that crash is however a Lancer Evo 4, which is older than the Evo 6, and has a different front bumper, bonnet and rear spoiler. (01:17:25)
Factual error: In "Pikachu and Pichu," when Pikachu and the Pichu brothers come to the big play structure thing, there are a bunch of Pokemon around, including a red-and-white, ball-shaped Pokemon called Voltorb. The dubbers for the English version made a very noticeable error here: instead of Voltorb saying "Voltorb," (almost all Pokemon say parts of their names when they speak) it says "Electrode," which is the name of a similar-looking, but different Pokemon. The two are both red and white, but the difference is that Voltorb has eyes on the red part of its body, while Electrode has eyes on the white part of its body.
Continuity mistake: When Wolverine crashes into the tree knocked over by Sabertooth, notice that the entire front of the truck gets completely folded up and the windshield breaks into a thousand pieces. In the next frame, Wolverine gets thrown through the unbroken windshield and the front of the truck is practically undamaged... (00:18:05)
Continuity mistake: In the third segment of the movie we see Davis, Yolei, Cody and their Digimon playing on the beach. In the wide shot when we see all of them playing we see that Davi's Digimon is in his "rookie" form, Veemon. When they show a closeup of him and Davis together, Veemon is now in his "in training" form DemiVeemon. Then they show them all playing again and he is now Veemon again.
Continuity mistake: After mowing down all the Immortals during the Sanctuary scene, one Watcher tells another to take their heads because they might be Immortals. You see the Watcher to the left side of the screen and a robed figure to his left about four feet away drawing his sword. Suddenly, that same robed figure is now to the Watcher right side and about two feet away.
