Guyver: Dark Hero picture

Deliberate mistake: During the final battle, at one point Sean kicks Crane off a rope bridge. When this happens, if you look closely you can see the rope railing on the side of the bridge fall away right before Crane falls. It's supposed to look like Crane is falling through the ropes, but they drop just a split-second too early (he's not even touching them when they start to fall), so it was done on purpose and mistimed. (It was likely timed to drop away just a split-second before Crane fell so that the stunt-person wouldn't accidentally get tangled in the ropes as they fell).

Scanners picture

Deliberate mistake: When the scanners escape the apartment in the van and the assassins are in pursuit there is a street view shot of the assassins driving up next to the scanners' van. If you watch the street on the right side of the screen you can see people stood watching the filming in groups, out of harms way. (00:50:28)

Abbott and Costello meet Frankenstein picture

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.

The Langoliers picture

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)

LEGO Star Wars: The Padawan Menace picture

Deliberate mistake: When C-3PO, R2-D2 and the younglings are driving through the battle zone, Anakin Skywalker and General Grevious can be seen battling. Later, Darth Vader can be seen on Hoth. This would be impossible due to Anakin Skywalker being Darth Vader. (00:08:50 - 00:12:20)

Superman picture

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.

Venom: Let There Be Carnage picture

Deliberate mistake: When Kasady and his symbiote are fighting for control at the bell tower, they are reflected inside Venom's eyes...who is lying on his back in the middle of the cathedral and is nowhere near and at the totally wrong angle for a reflection like that to happen. (01:15:50)

Super 8 picture

Deliberate mistake: The scenes involving the 8mm projector and screen did not also contain legitimate light rays from the projector to screen or show any obstructions on the screen despite Joe or someone else between the projector and screen. What showed on the screen is what would be expected if using a videotape or DVD.

Encounter picture

Deliberate mistake: Kurt was close to the passenger side when Malik shot him from the opposite side of the car, but he fell backwards some distance from the car (and not from the force of the bullet). (01:24:40)

The Last Starfighter picture

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.

Kids vs. Aliens picture

Deliberate mistake: After Sam freed Gary from being tied up by the aliens, Gary pulled off the cast he got earlier that day and was able to use his left arm as though it had never been broken. (00:45:43)

Reminiscence picture

Deliberate mistake: The angle of the light coming from the film projector (which was up high on the back wall) was too high to actually project onto the screen across the room. Also, people were standing in front of the screen and should have been blocking part of the projection and have light on their backs but did not. The screen operated more like a DVD player on a TV. (00:35:20)

Universal Soldier: The Return picture

Deliberate mistake: If this movie takes place 7 years after the original, how could his daughter be 13? He was part of a government project, I doubt they let them leave for relationships.

Suggested correction: This is a retconned film made after 2 other direct-to-video Universal Soldier movies were made. While the film is considered non-canon in the series, in the film itself, the facts of the original are altered to allow Luc to have a daughter.

Bishop73

Exactly. If this movie changes things that happened in previous films than they don't make sense in context to the series, that's a mistake.

brianjr0412

Essential the film can be considered the same as a reboot. Reboots and remakes can alter characters without being considered mistakes because they're not actually part of the film series, just like "Universal Soldier: The Return" is not part of the Universal Soldier film series. However, changes to characters in retconned films, shows, or books, by definition, are not mistakes.

The Darkest Hour picture

Deliberate mistake: This mistake was admitted to in the DVD commentary by the director. When at the embassy, once they open the window, the camera pans up to show a destroyed helicopter on top of the building. This is a mistake as in Moscow, it is restricted airspace for helicopters, with none at all for any purpose to be allowed to fly over the city, not even to land on the American Embassy. However, the director really wanted the visual of a destroyed helicopter on top of the building so added it anyway. (00:41:49)

Jurassic World Dominion picture

Deliberate mistake: The decaying tree trunk would have more than likely broken into pieces and/or uprooted from the force exerted by the rope tethered to the pulling Parasaurolophus when Owen wrapped the rope around the trunk to stop the heavy-weight dino, but the trunk held up without even losing a shred of bark. (00:08:36)

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.

Deliberate mistake: When Marge and Dick are being beamed in outer space, there's no way they could be breathing because there's no breathable air in space.
