Continuity mistake: In the scene on the Golden Gate Bridge when the apes are pushing the bus, the police shoot the bus numerous times, but when the camera goes off the bus and then shows the bus again (twice) the bullet holes are not there anymore.
Continuity mistake: When housewife Alice is trying to escape with her daughter in the laundry room, she slams a mop through the ceiling. When she slams the mophead through the ceiling the last time and pulls it out, the hole left behind is maybe one foot across. When she lifts her daughter up into the hole it is now a good two or three feet across and reaches from ceiling support beam to support beam. (00:09:20)
Other mistake: When Nick is in the spoon, the milk around him turns green.
Other mistake: During the lightspeed skipping sequence, there is a scene where two Millennium Falcons appear on screen.
Suggested correction: These are mirror spires, a reflective surface. It's not a mistake.
It was confirmed to be a mistake in rendering. The "mirror spires" was made up to try and excuse the error.
No, the director actually said that this was a planet that shows reflections. Because you can see the towers reflected.
Continuity mistake: In the cafeteria scene, Ripley gets a square of what looks like cake and pours half a glass of orange juice. When she sits down her glass is full. (00:27:00 - 00:27:50)
Continuity mistake: When Doug is running from the bad guys after finding out what was going on from his "wife", he tucks his big gun in to his jacket pocket. When he is running through the scanner, that big gun is now in his pants. (00:28:15)
Factual error: Take a look at Google Earth - the section of the Golden Gate Bridge Magneto breaks off (about a mile - tower to tower plus a section each end) isn't anywhere near long enough to reach Alcatraz from anywhere on the mainland.
Visible crew/equipment: During the freeway chase, when both the Hummer and the Dodge Magnum are shown flipping over at the same time, the "Bay Buster" camera truck is briefly visible in the background.
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)
Continuity mistake: In the scene where Dr. Grant and the others walk in on the feeding T-Rex, his mouth is slathered in blood. But when the T-Rex is battling the Spinosaurus, its mouth is clean.
Visible crew/equipment: After Reggie touches the metal poles, he goes flying backwards. As he hit's the floor, you can see a thick white rope attached to his left foot. (01:11:10)
Factual error: When Chicken Little is in his bedroom, after he scored during his baseball game, he looks into the spoon he is using as a microphone to see his reflection. He looks into the side that is curved away from you. When you look at that side of a spoon your reflection is upsidedown, but Chicken Little's was right side up.
Continuity mistake: In the scene where Rico is first in boot camp and Dizz says she is being transferred to the unit, she gets ready to fight the drill sergeant. She drops her papers, her jacket, and her bag. It cuts away for a few seconds, then goes back to the drill sergeant and Dizz in fighting stance. The piece of paper is farther back than before, this can be overlooked because of wind, perhaps. But the jacket and bag are both gone. (00:25:55)
Continuity mistake: When the eggs pop out of her bag and start cooking on the counter, they're in different positions depending on whether it's a close up or wide shot. (00:18:55)
Revealing mistake: After the trained chimp is shot and is crawling into the cage, they show a shot of an ape turning around. You don't even have to look hard to see it but there's a two inch strip all the way down his face with no makeup. Clear as day. (01:41:30)
Revealing mistake: When Frank is knocked down with the tray, the arms of the person operating Johnny 5 are visible when the robot turns to run.
Visible crew/equipment: When the blob just misses Laverne, you can see a crew member under the raft (probably operating the mechanical special effect).
Other mistake: When Leela is signing the petition, Amy grows a third arm for a split second.
Continuity mistake: Right after Marcus gets the Jeep to start, they begin running from the Aerostat. They start off going down a steep hill and the windshield is practically sparkling clean. Once they get to the road at the bottom, the shot shows the windshield caked with mud. (00:34:00)
Continuity mistake: During the first fight, the boots of Alice change from high heels to no heels and back to high heels several times. (00:08:10)
