Revealing mistake: When they (Finch and Frank) are on the boat to Ecuador, in the first shot you can see on the waves that the boat had sailed in what seems like a circle. (01:16:30)
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: 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.
Factual error: Saroo is in Melbourne in 2008 (as indicated by the text at the beginning of the scene). As Saroo and Lucy walk down the street on opposite sides, a red Nissan Qashqai is seen driving past. That car didn't come out until 2013.
Continuity mistake: Blood from Tom's shirt's elbow when he is attacked by Rachel appears and disappears randomly between shots.
Audio problem: On the beach, when Rodrigues asks when Inoue-sama will arrive, the Interpreter tells him that he is not coming. Rodrigues then says "He treats me kindly", but his lips do not move along with the speech. He just nods. (01:48:55)
Continuity mistake: When Jane has just found out she had been accepted into the school soccer team it's clear that on the soccer list it shows Jane is 9 years old, but when her moms speaks to her a minute later when Jane starts to worry about getting into college, Amy states that Jane is 12 years old. (00:06:25)
Continuity mistake: Gina arrives looking for first aid supplies. She has bruises on her arm. However the next day all the bruises have gone. (00:11:30)
Continuity mistake: During the opening credits the protagonist is talking with his parents. Throughout this, the whiskey in the bottle changes level depending on the shot. (00:01:20)
Other mistake: When the children arrive in Blackpool, Emma tells Jake that loop entrances can be anywhere and that "the one in London is in a subway tunnel", but on the map of all the loops they were viewing previously inside the boat, there was no marking of a loop in London.
Plot hole: The system providing oxygen can only be accessed by someone slim. Therefore John Goodman built the bunker with him unable to access the key facility that provides oxygen in his bunker. Yet he must have been able to go and get Britney when she went to that area?
Suggested correction: It's not a plot hole because he said in the film, the normal hatch to the air filtration was blocked by something that fell on top so they couldn't get through that way.
Other mistake: When Helen Mirren and Will Smith are standing on the subway platform and the scene cuts away to view them from the other side, we see them through the windows of a passing train. Dame Helen suddenly gets out of character and hastily answers her cell phone. She was playing a "spirit" on behalf of Will - not someone who'd have a phone. (01:04:00)
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: A group of people are in the copying room taking turns taking pictures of their butts on the copier. When one of them sits on the glass part of the copier, the glass part breaks. When he gets up, it's not broken.
Other mistake: During the climax, when Junior reactivates the baby manufacturing machine, the first baby to emerge from the machine is naked. The machine's hands diaper this baby. However, when the other babies emerge from the machine they're already wearing diapers. (01:15:45 - 01:16:25)
Continuity mistake: When Laina has to take off her clothes to change after she failed, there are no straps, meaning no bra. When she and Blake are changing by the pool, she has a bra on. She never had time to change/find one.
Factual error: The main character is being wooed by Lockheed - an aircraft company, whose representative then gives him gifts for his kids - one of which is a desk model of an aircraft, however it is of an aircraft produced by one of Lockheed's competitors - Grumman, which would be akin to a GM rep giving a toy Ford Mustang as a gift. Both companies continue to remain competitors as Lockheed-Martin and Northrop-Grumman since the government vetoed a proposed merger back in 1998, and at no time have the two companies collaborated on a major project.
Factual error: The present day "Grimsby" train station shows electric wires and trains. The real Grimsby only has diesel ones.
Other mistake: When "Santa" (Billy Bob Thornton) is in the bar with his mother, the bartender tells him that "smoking is not allowed in here." In the next scene, "Santa" is shown tapping his cigarette on an ashtray. If no smoking, why is there an ashtray?
