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.
Factual error: There were no SS in North Africa, as shown iat the beginning of the film. There was a small SD office in Tunis. If there had been, SS would not have paraded around in Black, or normal field grey for that matter, they would have worn most likely a tropical uniform.
Revealing mistake: When Austin goes to write the Roman numeral "XVII" on the chalkboard, the erased numerals from a previous take are still visible where he's about to write it. (00:41:36)
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?
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)
Factual error: Before departure, Captain McNeely asks if the ship's mission has anything to do with the Manhattan Project. The Manhattan Project was highly classified, and it is doubtful that McNeely had heard the project's name. In fact, there is historical debate as to whether or not he knew what the cargo was that he was carrying.
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)
Continuity mistake: After the meeting with the ghost of the mansion Erin hugs Abby and she gets the ectoplasm from her, but in the next shot it disappears.
Continuity mistake: After the seal runs away from Vera, the area where Vera is standing in the ice begins to crack. When Vera's phone starts ringing, her left foot is positioned around a foot away from the crack. Vera never changes her position, but when the shot is on her feet, her left foot has suddenly moved much closer to the crack. (00:22:05)
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.
Visible crew/equipment: In the beginning where Amanda Waller is talking in a restaurant. While the camera focuses on her towards the end of the scene, they move the camera right, facing towards her left side of her face. Watch the wine glass, you'll see the crew moving along with the camera.
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)
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?
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 wounds that Juda got on his face from the fall from the horse at the beginning of the film, disappear the very same day.
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.
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.
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)
