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: McVay gives the order to cease zigzagging, full speed ahead, but the Japanese sub commander gives the target speed of 12 knots for the torpedo solution. The Indianapolis was capable of a speed in excess of 30 knots.

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: 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.

Continuity mistake: In a second view at a different angle of the bank employee being shot, one of the doors that was shattered in the original shot is not shattered in the second shot. (00:03:02)

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: 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)

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.

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: 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.

Factual error: A bullhorn can be heard in the background off-screen during a battle with the zombies, even though the movie takes place during Victorian times. (01:19:30)

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.

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.

Continuity mistake: The level of snake wine changes in the glass as the camera cuts back and forth during the conversation in the Chinese restaurant between Jeff and Tim.

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 the credits, Tom Hopper sees and hears a bunch of helicopters and calmly walks indoors. He then addresses the waiter raising his left hand before the cut. In the next wide shot though we see him with a right hand raised that reaches for the champagne tray and grabs a glass. He says "Thank you" in a third shot, same angle as the first one, and in fact, the champagne flute is in his left hand now. (00:02:50)

Visible crew/equipment: A cameraman is in the bush at the start between the preacher and his mule. (00:01:06)

Continuity mistake: When Masovich kills Paolo, we see the slide stay locked in the open position. But in the next shot the slide is closed.

Continuity mistake: When Kurt and Kavi are washing clothes, the clothes change position on the line, specifically the red shirt at the end and the shorts Kavi hangs up. The red shirt is twisted around the line, but in the shot of Kavi hanging the shorts, the shirt is hanging perfectly straight down.
