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.
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.
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.
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.
Deliberate mistake: When Supergirl flies out of the lake upon her arrival to Earth she's wet. When she lands on the shore she's suddenly dry.
Suggested correction: Incorrect. She's not wet when she comes out of the water. She emerges from the water dry in an (incredibly wonky) effects shot. Why she's dry coming out of the water is unclear, but it presumably has something to do with the teleportation process for how she got to Earth considering her costume also suddenly appears on her as well.
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)
Deliberate mistake: When King Shark grabs the guard from behind and eats him, he screams loudly, but nobody reacts to it, not even his buddy who just went left to fetch a drink. Later Cena and Elba kill 'silently' every other guard, but when they get to a group of three that Bloodsport yo-yos to death, it's pretty impossible that those three could have missed the carnage just a little off to the left. Then again, at the end a whole tower gets demolished without anyone noticing, so It'has to be deliberate. (00:33:05)
Deliberate mistake: When Sam is watching the security footage of his predecessors being disintegrated in the chamber, the disintegration happens the instant the coffin door is shut. However when he goes in to test it himself there is a ~60 second wait as a congratulatory video plays before the disintegration occurs. (01:00:00)
Deliberate mistake: When Ben is discussing boarding up the windows to Tom, he says he still needs to get a few spots upstairs. Why would he need to board up the upstairs windows when the zombies have no way of reaching them?
Deliberate mistake: While Cohagen is on Mars, he calls Richter and chides him for trying to kill Quade. Richter is in a car on Earth, yet they're having a real-time conversation, which is impossible because of the distance. [While this is true, a movie with 4 to 21 minute pauses between lines would take rather a long time].
Suggested correction: This movie takes place an undisclosed amount of time into the future. Absolutely no telling what kind of technological advances could have taken place, in a science fiction movie at that.
Deliberate mistake: After Venom eats the head of one of the Drake's henchmen there is no blood from the wound.
Deliberate mistake: The filmmakers wanted a scene where Andi is startled by Max as he spacewalks behind her at Daedalus. Given that the only way to communicate in spacesuits is through radio, and the two suits would presumably been on the same channel with the shuttle, Andi would have known Max was coming. Further, even if they were on different channels, why wouldn't anyone tell Andi that Max was coming?
Deliberate mistake: Perhaps to avoid getting an R rating or parental complaints notice how in the operating room massacre none of the doctors appear to bleed nor do Doc Ock's tentacles have blood on them.
Suggested correction: The problem is in both versions of the film, basically all of the deaths either happen off-camera, or are things like people being shocked to death or killed by being tossed around and presumably having their backs/necks broken. Most of the deaths would be bloodless or near-bloodless anyways, and the camera simply doesn't linger on the bodies enough to show any blood. This is also why the tentacles aren't really bloody. Sure, it was probably ratings-related, but it isn't technically a mistake.
Deliberate mistake: In the very first shot of Korben Dallas, his bedside clock is facing away from him, towards us. We can read it, but he shouldn't be able to because he'd be looking at it backwards.
Deliberate mistake: After trying to get away from the monster, Costello finally unties the boat as Abbott rows away from the burning dock. The next shot of the boat has Abbott slowly rowing the boat, but you can see it's not moving as there's no wake, and when they jump off the boat after the Invisible man speaks, it doesn't rock, meaning the boat was mounted to something to prevent any movement, so they could make the jumps into the water.
Deliberate mistake: The surviving passengers are all awoken from a deep sleep after Dinah realises the other passengers have gone. Yet none of them appear drowsy or tired and none of their eyes appear strained, despite having just woken up so suddenly. (00:09:20)
Deliberate mistake: At the end of the film, when Alex, Maggie and Grig take off in the Gunstar, the crowd of trailer park residents watching them leave backs into the covered portion of the restaurant, right next to the 'Starfighter' game cabinet, which is readily visible in the shot. Mrs. Rogan then wonders where her younger son, Louis, is. The shot changes to show Louis pulling a bench up to the 'Starfighter' game to play it as dust from the Gunstar liftoff kicks up next to him while he watches it fly. Yet the crowd is nowhere to be seen in the shot of Louis playing the game despite everyone being huddled right next to it on the patio (his mother was standing next to it and should be able to see him). Given the proximity of the crowd to the game a moment earlier, Louis wouldn't be able to play it, let alone put a bench next to it. It's clear the filmmakers chose the image of the younger kid aspiring to be like his brother by playing the game over the logic of where the game was in relation to the crowd.
Deliberate mistake: Before Superman traps the black missile, its beam is really big and covers half of the lettering on the side. When Superman is behind, the fire is much smaller and the lettering is visible, allowing us to see Superman.
Deliberate mistake: When Casey is hiding behind the boxes waiting to knock out a Foot soldier and steal his outfit, you can see he is still wearing his denim vest. After he knocks out the Foot soldier, he is able to put on his entire outfit in roughly three seconds. (01:10:15)
Deliberate mistake: When a man bumps into pole, it sounds as if a truck had crashed (which makes it funnier), but in reality he just bumped his chest.
