Other mistake: When Adam comes in and says "when I woke up this morning, the pain was gone", Connie is mouthing his lines behind him.
Other mistake: Throughout the film Mason goes through all sorts of shenanigans - explosions, fire fights, falling off a cliff, almost drowning, this woman really goes through the wringer. It's a bit surprising then, that at the very end of the film when the good guys finally come to the rescue that she looks like she has just finished posing for a shampoo commercial with not a hair out of place.
Other mistake: In the slaughterhouse scene, after Harrigan has injured the Predator with his shotgun and Keyes reappears, the Predator throws its disc, and severs Keyes in half at the waist. We see his legs flop to the ground, and blood pour from above, but his upper half (torso, backpack and weaponry) mysteriously remain hovering out of sight. (01:21:50)
Other mistake: Murphy lands the helicopter on a railway line so an oncoming train will destroy it completely, and this happens exactly on cue with huge, dramatic explosions and flying debris. Apparently the train driver doesn't think this is important enough to interrupt his busy schedule - he doesn't stop the train. We do not hear brakes being applied - the wheels would make a noise like the sky coming down - and the train doesn't slow down at all - it just keeps on going.
Other mistake: At the carnival, you can see an African-American man staring at the camera for a while. I am unsure if he is a crew-member watching over the scene, or if he is just an extra trying to get onscreen.
Other mistake: When Rick and Ardeth Bay save Evie from the warehouse after Imhotep is resurrected, there are four mummies chasing them when they get on the double-decker bus. Rick shoots one of the mummies and "kills" it. He shoots another one in half and goes to the top of the bus to fight another one. The top portion of the mummy that got shot in half then fights Ardeth Bay. Evie kills the mummy that got shot in half and the top part of the bus gets torn off by the bridge and kills the mummy Rick is fighting. John stops the bus and they all sign with relief. Whatever happened to the fourth mummy chasing them? (00:43:20 - 00:46:40)
Other mistake: There is a scene in which Piter DeVries is talking about the Landsraad (one of the governmental organizations in Dune). Twice he mispronounces the name, saying "Lansdraad" instead.
Other mistake: When the hobbits are hiding under the tree trunk from the Ringwraith in the beginning, you can see space to the left and right of the tree above them. Logically when the Ringwraith walks past the tree you would see it on the right side of the tree first, then on the left, but you don't - it looks like it walks out of the tree instead of behind it. [Confirmed on the commentaries - Elijah Wood asks his fellow actors if anyone spotted the mistake: 'It kind of magically comes out of the tree'. Sean Astin: 'You mean it doesn't pass from the other side?' Wood: 'No, it comes out from the centre.'] (00:51:40)
Other mistake: The scene at Columbia University was filmed on an unseasonably warm spring day, however, the costume department had provided the high school extras with cold-weather clothing. The real Columbia University students can be seen in the background wearing shorts and t-shirts by contrast. (00:05:35)
Other mistake: The female journalist is called Samantha Coleman through the movie, but appears in the credits as Samantha Copeland.
Other mistake: How is it that one slash on Amidala's back ripped off the entire midriff of her shirt, and a sleeve? (01:47:00)
Other mistake: When Ray pulls up to Mary Ann's home, the front exterior layout and dimensions of the house are evident, from its near center front door to the two car garage, in front of Ray's van. The side exterior wall contains two large garage doors, which are about 35-40 ft from the location of the front door, with no small basement windows at ground level; inside, beside the front door, the stairs that lead to the basement run parallel just under the stairs in the foyer. In the basement, the small windows on the far end of the furnace room they run into are only about 20 ft from the basement stairs. Not only are the small windows non-existent in the exterior shot, but it's entirely impossible for two small windows to be where they are, considering the exterior footage of the house.

Other mistake: At the end of the film when they arrive in NYC looking for the library, we know that they survived because they are inside with a roaring fire burning. But where is the smoke up above, as Jack Hall approaches? There must be a chimney, or else they would have all died of asphyxiation.kiazersoza
Other mistake: When the Disco Volante separates to escape the cruisers firing on it, the "cocoon" is seen facing the pursuing ships stern first. When the shot changes to show the gunners firing on the ships the back half of the "cocoon" has turned completely around; the gunners are firing from the separated mid section of the Volante and the stern of the "cocoon" is now facing away from the cruisers, making it easy to see which parts of the scene were filmed live and which were done in the studio.demodon
