Deliberate mistake: When Lara and Terry escape the Shay-Ling, they are shown leaving the area and pass a sign that says 'Shanghai - 74 KM.' On a remote mountain passage, coming from a presumably well-secluded encampment. In English. Fat chance. (00:47:45)
Deliberate mistake: When Bilbo finds The Ring, he kneels down to get it. In the prologue in Fellowship Of The Ring, Bilbo is lying on the ground. The direction he looks toward when he overhears Gollum is also different.
Deliberate mistake: Before Dorothy is sent to Kansas there's a close-up of her shoes. All of the group's feet, Glinda's dress, and the rest of the elements around are gone and replaced by a black background. Despite being a deliberate directorial decision to give the shoes a more dramatic focus, it is really awkward to see everything disappear, nevertheless.
Deliberate mistake: When the house is splitting in two, the board game should have fallen long before it actually does. (01:25:25)
Deliberate mistake: When Kimberly is being revived, it's obvious that they are using a defibulator. But when Kimberly finally comes to and is covered by a sheet, you can see she has a bra on. This is impossible to have because you need direct contact with the skin in order for it to work. And the machine would start the heart working if it was lower on her chest.
Deliberate mistake: When the hillbilly is dragged into the cellar, the resulting explosion of blood has a much greater volume than the actual amount of blood in a human body. This is done to support the campy gore motif of the film. (01:03:20)
Deliberate mistake: On the DVD, in the scene where Jim Carrey finds a picture of his girlfriend (Jennifer Aniston), and holds it out of her reach, you can see that parts of the photo are blacked out, presumably to protect the identity of the person in the photo? (00:05:10)
Deliberate mistake: When Jonathan and Emma are beginning to know each other, they make their way to the wood shop, where Emma picks up an "air powered tool". The tool is a staple gun, but shoots two 3" nails close to Jonathan.
Deliberate mistake: When Gale and Lucy see the Blue Star for the first time on the Volcanic island, on the second shot of the beach, the sea and the boat and star, the view from the beach, it is a still picture, the waves are not moving. All of the characters are moving but the sea is perfectly still.
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: 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: During the entire movie nothing is mentioned about the rape of Merrin until the very end, even though it is quite obvious for a forensic investigator to determine she was raped, and something like that would be very important to help find a suspect. This is done deliberately to continue the plot as rape would make Iggy less of a suspect (being her boyfriend for years) and someone like Lee more (known by Iggy and others he had feelings for her).
Suggested correction: Boyfriends (and even husbands), are routinely accused of and found guilty of raping their partner. Given that they were seen arguing and told by the waitress that she saw Ig dragging Merrin to his car, there's no reason to think the police wouldn't suspect Ig of rape. We don't see any of the proceedings and we are told only a little bit of information about how the characters got to where they are at the start in order to build suspense, it has nothing to do with continuing the plot.
Deliberate mistake: When they are listening to the tape, Cheryl yells out and shuts it off. Scott says he wants to hear the rest of it, but then deliberately fast-forwards it a bit before starting it playing. If he wanted to hear the rest of it, why does he skip part of it? This allowed Cheryl to shut it off as soon as she finished her line/action, but then Scott could fast-forward it past a mark on the visible reel-to-reel tape so it would start immediately on the chanting rather than in the middle of the lecture where Cheryl stopped it.
Deliberate mistake: In the opening scenes just after the restaurant dialogue, as soon as the scene changes there is a quick cutscene which shows the screen zooming in on the Pentagon. If you look In the lower left corner, the text on screen gives the Pentagon location as being in Washington D.C. however, The Pentagon is located in Arlington, Virginia. (00:19:02)
Deliberate mistake: Several times, you see an exterior shot of Nathan's house, and it is very clear that it is the same shot being used over and over, sometimes reversed.
Deliberate mistake: When Gulliver is first placed in the dungeon, he is attacked by a tiny seagull, however comparing the size of the bird with Gulliver's foot, it appears to be about the size of a fully-grown Lilliputian. This was obviously done deliberately as a correctly-sized seagull would be far too small for the joke to be effective.
Deliberate mistake: When Spidey jumps on the hood of the truck, Rhino squirts him using the wipers. Funny, but he can do that only because the detergent sprays forward instead of the angle actual windscreen washers are pointed at. (00:12:50)
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: Rocks on the water suddenly appear when the rabbit shows up, which allow for Alice to chase him.
Deliberate mistake: All Minor Hockey Leagues in North America require players to wear visors with their helmets.
