Continuity mistake: When Fin stops near the school bus, the bus number changes from "278146" to "278245" during the rescue of the kids.
Character mistake: When Harley asks Tony what the light is coming from his chest, Tony responds "an electromagnet." Harley replies "What does it power?" An electromagnet is not a source of power. The arc reactor is the power source which powers both the electromagnet (to keep Tony safe from the shrapnel near his heart) and the Iron Man suit. (00:43:25)
Plot hole: The most secure prison in the world, designed with the advanced schematics of world leading prison-building architect (J.D Ray Breslin) has cameras somehow interconnected to one another so tightly that physically neutralizing one puts every other camera out of commission as well.
Continuity mistake: When Teresa is yelling and hitting Jordan because he cheated on her with the blonde girl in the limo, the car disappears and reappears between shots. (01:00:35)
Plot hole: Each of the four magicians are given a tarot card that has a date (March 29), a time (4:44pm), an address (45 East Evan St), and a city (NY). When they enter the building on that date, they know which apartment to go to. The problem with this is that it was never stated on any of the cards which apartment to go to once they reached 45 East Evan Street. (00:08:40 - 00:10:05)
Continuity mistake: During the dinner scene at Tom's, a couple of shots before Tom's phone rings and he goes to answer it, Nick's wine glass is about half full. After Daisy leaves to go to Tom and the shot cuts back to Nick, the level of wine in his glass has notably decreased, without him touching it. (00:09:50)
Plot hole: They aren't able to travel before the birth of their children or their children become different. Despite that, he visits his father one last time before their third child is born. His Dad and he then travel back to when he was a kid, which would have changed his first 2 kids.
Suggested correction: This is not necessarily inconsistent with the movie's time travel logic. Since Tim goes back in time to visit his father and inside that particular time travel, they use time travel to go back to a day where Tim was a child. Then, they return back to the original time travel where they're playing ping pong. At that moment, both of Tim's kids were already born. So, when he returns from the ping pong scene, there's no change regarding his kids.
Also, paraphrasing the Dad, he said they aren't going to change anything. It is more like reliving a memory than changing the future to get what you want. The Dad couldn't go back to not smoke before his kids were born because that was major and would have changed the course of his life; walking a bit differently on a secluded beach that you walked on in your younger days (as long as you spent the same amount of time - presumably) would not alter the trajectory of one's life.
The slightest change in 1 second of being on the beach would absolutely affect his kids. A man produces 1500 new sperm every minute. Altering the timeline and delaying every event that is going to happen by literally 1 second would most definitely alter which exact sperm was used when conceiving both of his first two children.
Continuity mistake: When Theodore goes to Amy for comfort in her apartment, there's someone (or something), walking at the front door, but then not again in the next shot. Keep your eyes top right, it's very visible. (01:26:50)
Continuity mistake: In the scene where Grug is chasing after Guy, they both wind up stuck in a tar pit. After successfully escaping they are covered in tar and Grug even gets himself stuck to Guy. In the next scene everyone is running from the exploding ground up between the mountains and both Grug and Guy are completely clean and free of tar.
Visible crew/equipment: When the young lady is trying to drag her dead husband away to bury him, as she takes a hold of the blanket you can see the covered wagon in the background and someone's legs behind the wheel begin to move to the right. She was suppose to be alone except for her dead husband. (00:34:00)
Continuity mistake: Lotte barges in the pizza place and carves her name onto Shaggy and Scooby with her sharp nails. LOTT on Shaggy's shirt, and the E in Scooby's fur. They run out the door and then come back to pay for their food. Suddenly the rips in Shaggy's shirt and the scraped off fur on Scooby's chest have vanished. (00:23:45)
Other mistake: The old man executed in District 11 was shot in the head from behind. However, when Katniss looks out the window from above there are no blood stains on the floor, nor is there a gunshot wound to the head. (00:20:50 - 00:22:30)
Factual error: The coastal wall in Sydney is shown as being inside the Sydney Harbour (right next to the Opera House). But Sydney Harbour is not on the Pacific coast but a part of the Parramatta river, several kilometres from the ocean (where the wall should have been). So the wall is either not shielding the northern part of Australia or (more likely) the producers decided that the audience cannot tell that it is Sydney unless we see the Opera House.
Suggested correction: This entry is wrong. According to the world-building of the universe, the area that would need the wall was destroyed by a previous kaiju attack, meaning that nobody would live there; thus, there is no need for a wall.
Other mistake: Sam draws an orange vest for Lockwood using a dark crayon. (01:10:45)
Continuity mistake: When Sandy takes a taxi and goes to Diane's house, as he is arguing with her, the sweat pattern on his shirt changes several times as the scene switches from him to her and back.
Continuity mistake: After Batman shoots Reverse Flash through the head, Flash rushes over to Batman and catches him before he falls over from his wounds. As Flash is lying him down slowly, there is no blood on Batman's face. It then cuts to a close up as Batman reaches up to pull off his mask and there is suddenly blood on his lips and chin. (01:12:20)
Continuity mistake: In the shot where Holly is done injecting Anna with the syringe and stands up to shoot at Detective Loki, the syringe and two "medicine/poison" bottles are all close together next to Anna's hair. Next three shots showing the room far out with Holly getting shot and killed has the two bottles next to the edge of the rug and very far from Anna's hair, as well as the syringe which is slightly closer, but far away. The next shot of Loki picking up Anna has the syringe and bottles in their original position next to Anna's hair.
Continuity mistake: Approximately two scenes after Kitai leaves the pigs' burrow where he sheltered for the night, the "cutlass" is suddenly missing from his backpack. He later retrieves another from the ship's tail section. There is likely a deleted scene which would have explained the loss of the cutlass.
Continuity mistake: In the bathroom after she feels sick, Jackie's wife is at the sink. After a brief conversation, another woman tells her she might be pregnant. She looks at the mirror with her mouth open as she thinks. It cuts to showing the mirror and her reflection shows her mouth closed.
Factual error: The Whyte character says it is Checkmate even though he moved the queen into a position that doesn't threaten the king and could not have blocked anything that does threaten the king. You can also see all positions that might threaten the king, and none of them do. (00:27:40)
