Star Trek IV: The Voyage Home picture

Other mistake: After they take off from California, Kirk gives a heading to Alaska. He then tells Sulu "full impulse power", and Sulu says "aye, ETA 12 minutes." Full impulse is 1/4 the speed of light. No way they would use speeds like that to go a few thousand miles.

Dark Phoenix picture

Factual error: The space shuttle is spinning due to a stuck thruster. In such a case, the spin would be continually increasing as there is no air resistance. The X-Men shoot out of the thruster and the spin stops. Not factual. They would have needed opposite thrusters to stop it. (00:11:55)

Dawn of the Planet of the Apes picture

Factual error: When Koba steals an Armored Security Vehicle class M1117A Guardian, he kills the gunner from the turret and then somehow manages to use the 240B attached to the turret. First, it takes three men/apes to operate the ASV, and second, the ASV cannot be operated from the turret. In that scene, it is assumed that Koba is operating the entire vehicle, something most humans cannot do or do not know how to do. Let alone a 240B, MK19, or .50 Cal M2 Browning. The ASV turned in the direction of the wall, which was the only way that the Apes were able to breach the city walls. This is also kind of an important plot hole blunder too because if it were not for the breach from the ASV, the Apes would not have won. The other blunder from this is that the gunner would not have been exposed from the hatch, since the ASV was using .50Cal and MK19. No need to use the 240B.

Star Trek: The Motion Picture picture Star Trek: The Motion Picture mistake picture

Continuity mistake: In the final scene on the bridge, Spock and McCoy are wearing colored arm bands which identify their departments: Spock's is orange (for Science) and McCoy's is green (for Medical). In the very last shot, Spock is wearing the green band and McCoy is wearing the orange one.

Aliens vs Predator: Requiem picture

Continuity mistake: The birth of the Predalien in this movie is completely different than it was in the first AVP. The lights on the table are different and the Predalien bursts out differently than in the first film. (00:01:30)

Starship Troopers picture

Continuity mistake: Toward the end, Carmen Ibanez gets stabbed through the shoulder when she is brought before the big master alien thing. If you were to sustain such an injury, there would be so much swelling, not to mention just destroyed tissue, that you wouldn't be able to move that arm for weeks. Yet a few minutes later, she is seen hefting around a very large assault rifle, and seems to have no difficulty. I guess it's a pretty standard action movie "heroes can temporarily ignore injury in order to save the day" kind of oversight, but it just seems exaggerated in this case, considering how severe the shoulder trauma looked. (01:48:15 - 01:53:40)

Star Wars: The Clone Wars picture

Other mistake: During the Battle of Teth (the pillared jungle planet), the AT-TE's shoot the ledge at the top and there's not a single mark on the ledge afterwards, despite being hit with several joules worth of fire.

Space Mutiny picture

Continuity mistake: While this movie is so bad and full of mistakes, its barely worth finding them all, one stands out in the history of movie mistakes. One of the officers on board the ship, Lt. Lamont, is killed by the villain. A few scenes later she shows up on the bridge as an extra.

Baby Geniuses picture

Continuity mistake: When Sly is in the attic, and the fake power dude comes up to kidnap him, Sly uses a ski to "hit him in the gonads". But if you look closely at his face, the guy who was hit in the nuts wasn't the same guy that fell down the stairs.

Blade Runner picture

Other mistake: When Deckard visits the Tyrell Corporation, he prepares to test Rachel with the "VK" machine. He is shown putting his briefcase of the table and lifting the "VK" machine out and onto the table. If you look closely, the "VK" machine is already on the table and Harrison Ford is miming the lifting - there is nothing in his hands! (00:19:45)

About Time picture

Plot hole: They aren't able to travel before the birth of their children or their children become different. Despite that, he visits his father one last time before their third child is born. His Dad and he then travel back to when he was a kid, which would have changed his first 2 kids.

Upvote valid corrections to help move entries into the corrections section.

Suggested correction: This is not necessarily inconsistent with the movie's time travel logic. Since Tim goes back in time to visit his father and inside that particular time travel, they use time travel to go back to a day where Tim was a child. Then, they return back to the original time travel where they're playing ping pong. At that moment, both of Tim's kids were already born. So, when he returns from the ping pong scene, there's no change regarding his kids.

Continuity mistake: During the street chase in Brazil, the time of day changes from night, to perhaps late afternoon/evening, to night again.

Alien Vs. Predator picture

Factual error: When they're first entering the whaling camp, a penguin startles Miller. That penguin was a black-footed penguin, which is a bird native to much warmer climates. If that little guy had actually been in Antarctica, he would have died within minutes. (00:20:40)

Demolition Man picture

Continuity mistake: When Simon Phoenix gets out of the sewer system (after gunning it out with the rebels and John Spartan) his left eye has the brown contact and his right eye has the blue one after going the entire movie with those contacts in the opposite eyes. (01:30:25)
