Factual error: When Tripp enters the garage and we see his truck in progress, he states that the truck will have 425 horsepower. The Hemi pulled out of the Terravex truck is not a 6.4L Hemi (only a 5.7L Hemi) and even if it was a 6.4, they only produced 410 horsepower in the heavy duty trucks. The 5.7L Hemi makes 375 horsepower in the trucks and 390 horsepower in the cars.
Plot hole: When the dome of crystal collapses, all the animals inside immediately grow old, including Brook, implying that the magic from the crystals is completely gone. However, when a tiny piece of crystal lands in the hot spring, it creates a 'fountain of youth' which the animals then bathe in to regain their youth. If that little piece of crystal worked, then why didn't the many crystals from the broken dome still work? Also, how is Brook able to leave the fountain of youth and go looking for Sid at the end of the movie without growing old?
Factual error: The present day "Grimsby" train station shows electric wires and trains. The real Grimsby only has diesel ones.
Continuity mistake: When they are in the big hall he goes to demonstrate that he can shoot. He shoots 5 arrows. When you see the arrows hit the bowl only three hit. (00:32:00)
Sometimes he shoots 2 at a time. He does shoot 3 times, but he shoots five arrows.
The correction is valid. He never shoots 2 arrows at once. You may need to watch in slow motion if you can't see what happened. He grabs 3 arrows with his right hand and keeps them in his hand as he shoots 1 arrow at a time. This is probably most obvious on the 2nd shot where you see the 2 arrows in the bow, but when he releases his hand, you see one arrow still in his right hand and 1 arrow leaving the bow.
He starts holding all 3 arrows, shoots 1, reloads holding 2, shoots 1, then reloads and shoots the last arrow.
Continuity mistake: The protagonist is fondling his pregnant wife in bed when she pinches his nose. Between the two shots the blanket covers /uncovers the baby bump, and her hair is bunched on the pillow in entirely different ways. (00:01:40)
Continuity mistake: At the end, when Gloria hurls Oscar completely out of sight beyond the horizon, a huge crowd of South Koreans rush up directly behind Gloria, cheering and applauding, only a few feet away from her. The camera cuts to a frontal shot of Gloria, and now the crowd is 30 feet or more in the background.
Continuity mistake: The crew arrived at the volcanic island in turmoil, and are talking with the local captain. The captain asks them to carry also some of the dead people, and they start asking him what the plan is, if there's one at all. The pass at the neck of the captain shows the side with the symbol in one shot, the blank one in the next. (00:25:10)
Continuity mistake: Jane is back at the dinner table after supposedly recovering from her illness. In the wide shot of the room, Mrs. Bennet says "I know of no-one who is coming." Mr Bennet at the other end of the table is sitting back, hands off the table. But, he answers in a close-up, where he is buttering his toast. (00:32:35)
Continuity mistake: In the first scene, the old alien man comes to pick up his spaceship and Ratchet instructs him to "Now, let's fire up that mag booster." The old alien pushes the switch forward to start the mag booster. Later in the movie, Ratchet flips the switch backwards to "engage mag booster" as Clank commands. (00:06:30 - 00:26:30)
Continuity mistake: The bank employee is dragged back towards the doors (seems to have been propelled a long ways backward). but he shows no sign of bleeding from either arm, one of which had been stabbed. (00:03:44)
Continuity mistake: When Batman and Batgirl are about to have sex on the roof, Batman lets his left hand slip down from her back to her butt. In the next shot, it's on her back again.
Visible crew/equipment: A cameraman is in the bush at the start between the preacher and his mule. (00:01:06)
Continuity mistake: At the beginning of the movie, the hunter is looking for his dog. The rifle on his shoulder keeps changing position, being upside down or not - which is easy to spot because of the big scope. (00:01:30)
Continuity mistake: The gang Bo is reluctantly part of gets to Maurice's crib where he is playing cards with his homies. The red jacketed one is defiant, and grabs a handful of red and blue chips in front of him tossing them in Angelo's face. But if you check out of the table in the wide shots before this occurs, you'll notice that red chips were never in the stack in front of him to begin with. (00:19:05)
Continuity mistake: While Jax is held against the wall by two of the Furies it shows her bare feet held off the ground. As she moves across to Sinbad after he plunges the sword into the third Fury she is wearing flip-flops. (00:29:17 - 00:29:54)
Revealing mistake: Despite Sigourney Weaver supposedly having had her fingers cut off if you watch her when she's in her straitjacket you can see her fingers moving around.
Revealing mistake: Set in Pittsburgh, PA, scenes were obviously filmed out of sequence. Many scenes were "out of sync" with the snowfall, whether in progress or amount (if any) already accumulated. For example, there was no snow downtown, but views from the helicopter showed snow-cover around the nearby parkway (Route 376). In another scene, it was snowing when Ryan turned his Jeep into a downtown road that was covered with at least one inch of snow; switching to a "live" newscast, the sun was shining outside.
Revealing mistake: In the opening scenes, we see a very pregnant Draka reclining on a bed of animal hides as Durotan watches over her. In the extreme closeup, we see Draka twitch her lips, and her small tusks flex from side-to-side with her lips, instead of remaining firmly aligned with her jaw as they should.
Revealing mistake: When Gabby and Fin are hanging off the building in Las Vegas, you can see that Gabby isn't holding on to anything in some close-up shots. (00:11:47)
Continuity mistake: After their fight with the monkey Sara has some scratches on her forehead and cheekbone but when she gets to the castle with Freya they are gone.
