Revealing mistake: When Anna and Hans are dancing in front of the lighthouse, we don't see the shadow of the railing or the ground they're standing on.
Revealing mistake: Early on, after Clary blasts the demon with a homemade explosion that blows a huge fireball across the kitchen and blasts out the window, there is no sign of anything being burned, not even the curtains. The kitchen is only in a slight shambles and there are small fires burning in isolated areas that never spread or char anything.
Revealing mistake: When the freeze frame for Swindel comes up, he is being interviewed and looks at the camera. When time is supposed to resume, the Channel 3 news logo moves, but Swindel on the television is still frozen for about a second for some reason.
Revealing mistake: When Roderick confronts the monk, a plastic outline can be seen around the part of the monk's hair that has been shaved off.
Revealing mistake: In one of the first scenes, one of the characters is standing with an umbrella close to a landing helicopter - without the umbrella being the least affected by the wind.
Revealing mistake: When Smaug confronts Bilbo and weaves around the gold in his lair, as the dragon asks "What else do you claim to be?" his tail passes through one of the pillars (audience's left).
Revealing mistake: Barry is handed a file at his work. He starts reading it but the paper is totally blank. (00:12:35)
Revealing mistake: As the gang is watching The Phantom on the security monitors, he turns around and takes off down a hall. The only lights in the hallway are suspended from the ceiling in the center. Yet the Phantom's shadow is cast to his right on the wall, when there are no lights to his left. (00:10:50)
Revealing mistake: When Khan and Spock are fighting on the garbage scow as it glides over San Francisco, you can easily see Spock's stunt double being beaten by Khan's stunt double. And vice versa.
Revealing mistake: In the funeral scene where Dr. Viper Lady is videoing Logan fighting, she starts lowering the smartphone, but the "faked" image on the screen doesn't change to match her arm dropping down.
Revealing mistake: When Jack says "Screw you" to Sergeant Sykes, Sykes pulls his pistol and shoots Jack. You see the gun flash, and you see an impact on Jack. But if you watch closely, they do not line up. The special effects charge goes off indicating the hit on Jack's right breast. But when the gun goes off, while still moving, at that moment it was pointing at Jack's lower left abdominal region. (00:58:50)
Revealing mistake: When Walter is floating in the water, his shoulders are well out of the water because Ben Stiller was wearing a lifejacket under his shirt. In real life, he'd be up to his neck and have trouble keeping his head above water.
Revealing mistake: Right after the huge bird soars back to the trees and Kitai begins to run along the river something has either been moved or cut from the scene...look almost to the bend in the river in the rocks.
Revealing mistake: When Oz first meets the Munchkins, some of them begin flipping down some stairs. The animation of this is very jerky and noticeable. (01:20:30)
Revealing mistake: Close-up views of Billy riding Allie on the mini-bike (trying to escape the men following in the Jeep) did not include the lower half of the mini-bike; they were probably on a platform/trailer being pulled by a car. A 12-year-old (?) boy would have difficulty steering and maneuvering a mini-bike with a rider similar in size/weight and would have undoubtedly wrecked when he turned his body around from the waist up to look in back of him at the tailing Jeep. Billy also kept turning the throttle. (00:25:40)
Revealing mistake: In each one of his scenes, every time you see Captain Fuller you can see that the actor is wearing contacts to make his eyes blue. It's obvious contacts with the brown rings of his natural eyes around them. And contacts were not invented for a long long time after this movie takes place.
Revealing mistake: Robin is running away from company investigators. He comes across a supposed wire link fence. He breaks it with his bare hands, and by the flapping of the open piece you can see it is made with strings not wire.
Revealing mistake: At the end when the drone crashes in front of the car and the soldier gets out you can see the footprints in the sand from previous takes, in the exact spot where he steps.
Revealing mistake: Just after Superman and Supergirl have their talk about him going after Brainiac, it cuts to Lois at the Daily Planet on her laptop. There is a close up and you can see her fingers on the keyboard. She is typing really fast, but the animation shows her fingers just hitting the same 3 or 4 keys over and over again. (00:20:05)
Revealing mistake: When the 47 Ronin write down their names to swear fealty to the mission, they are cutting their thumbs on the swords to imprint their fingerprints on the document. The mistake is that they use the blunt edge of the sword to do this.
