Fahrenheit 451 picture

Deliberate mistake: Montag's hair gets intermittently shorter, longer and shorter again (and acquires a "cow lick" that wasn't there before) near the end of the film. (Oskar Werner had clashed with Francois Truffaut and deliberately had his hair cut to spite director.)

Deep Rising picture

Deliberate mistake: At one point during the big escape chase scene, Finnegan takes a turn and the jet-ski he and Trillian are on side-swipes a wall and it's clear that they're about to fall off. The film cuts away briefly and then we see them and they're zooming along again as though nothing happened. The scene is portrayed in real-time so there's no way they had time to spill, get back up again and build up enough speed in the time between edits. Slightly sloppy editing. (And this is not referring to the other moment in another mistake where the same thing happens when they exit the boat. It actually happens twice during the scene - that moment and this one).

Ghostbusters: Afterlife picture

Deliberate mistake: When the kids are about to jump start the trap Phoebe hides behind the school bus door. Half a second later, when the trap opens, she's nowhere to be seen, not even jumping or stepping inside the bus. Then half a second later she has managed to get inside, turn around and protect her head while the bus windows burst. It all happens in real time for their hairs are still fluttering. It sure paces up the scene, but it's really awkward.

Star Trek VI: The Undiscovered Country picture

Deliberate mistake: It's not particularly believable that the away team to stop the assassination would consist of the ship's entire senior staff, and raises the question of who was left in charge of the bridge (the answer: apparently nobody, as they return to a completely deserted bridge). Of course this is dramatic license, and at this point the audience won't care or likely even notice.

Face/Off picture

Deliberate mistake: When they fight in the hangar and Troy is thrown back by the jet engine, his face and other parts of his body should have been burnt quite heavily. Such a jet engine has temperatures higher than 450°C about 5 meters away, and Troy is even closer than that.

District 9 picture

Deliberate mistake: After the SAD unit shoots down the command module, Christopher falls to his knees in sadness. In the next shot, the mercenary supposed to be pointing his gun at his head is looking and pointing as if Christopher was still standing, as revealed when he actually gets back up again.

Iron Man 2 picture

Deliberate mistake: The whole Monaco race sequence is totally (but deliberately) ludicrous. First no driver would be allowed without a fireproof mask and rest of required security measures, as Stark does. Second, the real-life security controls are very strict: When an accident occurs a safety car shows up, flags and audio advices signal the racing cars for them to lower their speed and avoid accidents. Nothing to do with the wild, uncontrolled race depicted here.

Robocop 2 picture

Deliberate mistake: When Robocain tries to use his chaingun on Robocop and it isn't armed, he snatches the remote unit from the OCP psychiatrist. If you look carefully, the remote unit changes from real to animated as soon as he grabs it.

Blade Runner 2049 picture

Deliberate mistake: When Deckard wakes up in Wallace Corporation, there is a wide shot of the platform he is on. All four corners of the platform are empty in the wide shot. Deckard then looks at Wallace's visual aids as they float away, and then realises Wallace is standing in the corner directly facing where he is sitting, speaking to him. This corner was empty in the wide shot, with no sign of Wallace. Wallace could not have entered in between shots because Deckard would have seen him approaching or at the very least, heard his footsteps. This was likely done intentionally as to not give Wallace's reveal away too early. (02:08:55)

Megamind picture

Deliberate mistake: When Metro Man flies towards the observatory to save Roxanne, we see a typical "the-characters-see-what-the-audience-sees" shot - a Super-Man-esque shot of him with his arms stretched out in front of him with his fists clenched. This shot is then projected onto a monitor that Minion is watching. It would be impossible to achieve this. It's as if there's some sort of camera on top of the observatory filming Metro Man, which there isn't. We see the observatory enough times to see that there isn't, and even if there was, the angle at which it would need to be at would be impossible to achieve. The shot of Metro Man on the monitor is positioned right in front of him, panning backwards. A camera would need to be very long to achieve this kind of shot, but there simply isn't one present.

Resident Evil: Retribution picture

Deliberate mistake: Empty magazines aren't that heavy, but when Alice kicks it into the face of one of the zombies, it looks like he's being hit with a baseball bat. (00:22:45)

Skyline picture

Deliberate mistake: When Jared is picked up at the airport in the limo, after the scene where the limo is driving down the interstate it cuts to a shot of several tall buildings. In the street at the bottom of the shot, the traffic is moving backwards if you watch the facing of the vehicles. Looks as if the film plates were flipped. (00:06:30)

Back to the Future Part III picture

Deliberate mistake: During the train sequence at the end of the film in 1885, it is blatantly obvious that the train is not going the speed that the DeLorean's speedometer is showing. In some shots, the train looks as though it is going little more than 20mph. (01:38:55)

Evolution picture

Deliberate mistake: The energy the meteor would displace upon impact would have created a crater of significant size compared to what was portrayed. It also didn't appear to have any impact to the structure of the cavern it crashed into either.

Universal Soldier picture

Deliberate mistake: At the start of the movie when the articulated truck is leaving the aircraft, you never see the attached trailer until the truck is completely flat on the runway. This is because of the steepness of the loading ramp, the trailer would ground and get stuck on the ramp.

2001: A Space Odyssey picture 2001: A Space Odyssey mistake picture

Deliberate mistake: When Dave is in the pod arguing with Hal to let him back in, various patterns of light are projected on Dave's face presumably from the video screens that say NAV and COM and such. Light on such a screen would diffuse and not project like this. It is likely those screens had rear projection and they merely removed the screens for this effect.

Short Circuit 2 picture

Deliberate mistake: When Johnny Five is assembling the first toy robot, he takes a screwdriver to the neck and body of the robot toy, even though there are quite obviously no screws there for him to tighten.

2010 picture

Deliberate mistake: Dr. Chandra returns to the Leonov at the end of the film with the device that Dr. Floyd designed to cut HAL's memory circuits. He hands the device back to Dr. Floyd, who tosses it in the air and catches it when it falls back into his hand. One problem - there was no gravity on the ship at the time. (01:44:00)

Mad Max 2 picture

Deliberate mistake: When Max opens the dog food, the lid should be all jagged because of the type of can opener he uses, but when dog and the gyro captain have the can the lid is cut smoothly. This was done so dog didn't get cut whilst eating out of the can.

Lockout picture

Deliberate mistake: The bomb is placed on M.S. One and Snow and Emilie get in the space suits. A cut to the bomb shows 14 seconds. Then back to Snow and Emilie as they talk for a bit. About 14 to 15 seconds go by, and then it cuts back to the bomb, which now shows 10 seconds... It counts down to 8, and then cuts back to Snow and Emilie as they run and jump out of M.S. One. The shot lasts about 7 or 8 seconds, then cuts back to the bomb, which now shows 2 seconds. The timing between shots and syncing with the bomb is way off here. (01:20:20)
