Continuity mistake: When Nick Cage and the woman get to her place and start to make out, he takes her bra off, leaving her bare chested as he fondles her. It cuts to a different angle as they are kissing and suddenly her bra is back on again, only to be gone in the following shot.
Continuity mistake: When Captain opens the bridge gate he puts his right hand to his chest. From the opposite shot it's down.
Plot hole: When Rupert brought his "secret pen pal" letters from Hollywood movie star John to school, they were stolen by some classmate bullies (and apparently never recovered). Rupert would have been around age 11 (possibly 12) at the time. It is inconceivable that a child could recall enough details from the letters to write a book about them 10 years later.
Continuity mistake: Felix on his skate jumps over a rolled-up rug some movers are carrying in the middle of the street. He jumps and the street is in the shade, he skates away and the street is full of sunshine. (00:01:30)
Continuity mistake: On his way to work, Antonio meets his ex Camilla.During their conversation, as it's particularly evident in the subway stairs sequence, passersby vanish every time the camera cuts to another angle. (00:08:00)
Continuity mistake: In the vault scene arguing/fighting with Gunnar, Taj/Lars had a clump of hair sticking up in the middle of the top of his head during most front views, but not rear views. (01:03:10 - 01:04:11)
Character mistake: When recruiting Burt to help repel the Graboid attack in the arctic, one of the team members says he's ideal for the job because of his experience hunting them on two continents, a reference to the first two films (Nevada and Mexico in North America) and Tremors 5 (Africa). However, this repeats the mistake in Tremors 5 in overlooking the Argentina incursion stopped by Burt at the beginning of Tremors 3, which gives him experience fighting Graboids/Shriekers/Ass-Blasters on three continents, not two. Burt, himself having overlooked Argentina in Tremors 5, does not correct her. And it's not as if the film is completely ignoring Tremors 3, since it shows the flashback of Burt being swallowed by a Graboid in that movie, which is how he got infected with the deadly parasite killing him here.
Continuity mistake: Kevin and his daughter handed the invite for the dream-like contest to the protagonist. He shoos her away saying "Liv, don't you need some milk with that cookie?" His arms are crossed behind his back. Next shot and she is walking away from him with his hands crossed in front of his crotch. (00:02:20)
Continuity mistake: After performing 'surgery' on the bear, Tasha goes visit another one of her little patients. Before she sets foot in the room bickering with Jeff you can see her hair flows left and right of her colourful pin on the coat. Inside the room, her hair is just on one side, switches side, and it stays that way till she exits the room, when once more there is a visible change at the cut. (00:03:30)
Continuity mistake: When Butch is talking to Dawn in his room, he puts on his headphones and begins talking to some unknown being and seems to be in a trance. His head is resting flat on his pillow as he grabs Dawn's arm. Just after she pulls away, Butch's hand is in the position as if he was still holding her. However his head is now resting up on the headboard. He couldn't have propped himself up with his hand in that position, especially in the matter of a few seconds. (00:40:40)
Continuity mistake: The clothes Tyler and Kassi were wearing at Kassi's house were not the same when Kassi came to dinner that day at the Burnside's house. It seems unlikely that BOTH would change clothes before dinner. (00:31:49 - 00:32:40)
Suggested correction: Apparently they did. It was probably Tyler's idea, presenting Kassi in the best possible light to assuage suspicion and maintain his image as a good Christian Boy Scout.
Continuity mistake: In the opening scene with the skype call, Mia's hair is in front/behind her shoulders depending on the camera angle, with no logic. (00:00:55)
Revealing mistake: The tapered half of the baseball bat was leaning against the coffee table at about a 60° angle, but after Dave said, "The bat?" the camera showed it sticking straight up from (perpendicular to) the floor. Dave's lower body is then shown walking past the bat (which reaches to his waist) and stopping, at which point the bat fades into his leg until it is almost invisible. The next view of the bat shows it leaning against the coffee table again, but the coffee table is closer to the couch. (00:09:08)
Continuity mistake: Batista knocks out of the three cops; the one that is lying further down the street is lying down at distance from the wall and oblique to the street's direction. In the overhead shot when the two staffers get back to the hotel, that cop is tucked in close to the wall. (00:32:55)
Other mistake: After the three kids took the car and caused a 19-car pile-up on the 141, Social Services got a court order removing them from the home and parents were not allowed to see them. Social/Child Welfare Services try to maintain or preserve the family unit and view removal from the home as a last resort or in cases of severe neglect or abuse that endangers the child. Social Services would not be likely to take such drastic measures for this incident. The driver may have been adjudicated a PINS.
Continuity mistake: Deanna is playing racquetball with her friend when she hits her in the lady parts with the ball. The two sit down by the wall; look at the bottle Melissa McCarthy is holding; it's practically empty, but in the closer angle when she sobs "What am I doing?" it is almost completely refilled. (00:09:50)
Revealing mistake: At the beginning of the movie, the protagonists dump the corpse of an agent in the middle of nowhere. The guy is stone cold dead...but you can see the carotid pulse on the right side of his neck, under the fake blood. (00:03:10)
Continuity mistake: The middle curtain on the passenger side of the RV is pulled open to different extents (toward the sides) when Drake is snooping around. Depending on the camera's view, maybe a foot of the curtain can be seen to the right. The other views show much more of the curtain, indicating it is not pulled to the side as far (and might possibly be closed). When a larger amount of the curtain is showing, there is also a small section of a pleat partially on the sill. (00:04:00 - 00:04:27)
Continuity mistake: LA Bar after their arrival. Tim Roth asks Uma Thurman why Irina hates her so much. Her glass is on the table then in front of her lips, in a sudden change. (00:19:55)
Deliberate mistake: Luke had a box of T-shirts he designed and Faith reached into the box and removed the top T-shirt. Without looking at the size or even holding it up to her body to see if the T - shirt would fit, Faith asked, "How much?" Luke replied, "Ten" [dollars]. Faith reached into her pocket, pulled out a wad of bills and handed it to Luke without counting the money. Faith put the T-shirt on over her top and it was a "perfect fit." (00:03:55 - 00:04:37)
