Continuity mistake: The two cucumber slices that Jesper puts in the palm of the Drill Sergeant change position between shots - in particular, in the close-up with Jesper walking away and putting the teacup in his hand as well, the two slices are side by side, while they are instead one on top of the other before and after. (00:02:25)
Character mistake: Right at the beginning of the movie, introductory technobabble. "In this canister, there's a solution of protons. The canister is attached to a rotor circuit that generates the protons to the speed of light." I believe the science genius and creator of time travel mixed up the words "generate" and "accelerate" here. (00:00:50)
Continuity mistake: When Gatsby and Chan are talking in the taxi, her hair appears to be tucked behind her ear when the camera is on her left but it isn't when the camera is on the right. Every time the camera changes, the difference in her hair can be seen. (00:33:51)
Continuity mistake: Throughout the movie in several scenes the living room has 2 couches even up until the Parks are getting ready to leave for their camping trip, 1 big one and one small. The very next scene when the Kims are getting drunk, the small couch has disappeared. This must be to make room for the Kims to slide and crawl out from under the table. The strange thing is when the Parks come back home, they don't notice that one of their couches is missing. It remains missing until the end.
Continuity mistake: At the skate park (which is supposed to be Thursday after school), Max is wearing the clothes he wore on Wednesday and Friday - not the clothes he wore in school on Thursday.
Factual error: The family supposedly left Ex-Yugoslavia (what part isn't made clear exactly) "because of the war", but the only conflict still going on there in 1999 (when the family is still there in the opening scene) was the NATO bombing of targets in Serbia in order to get the Serbs to lay off Kosovo, and that was long over by Christmas of that year.
Continuity mistake: When Ash and friends are entering the wharf, there are two people that change between shot. There is also a person who goes from having his right hand in his lap to having it scratching his head. (00:23:06)
Factual error: She fires the entire magazine of a Glock into the alligator's mouth. When it is empty, rather than the slide locking back and the trigger freezing, there is an audible click every time she pulls the trigger. This could not happen.
Character mistake: Queen is an attorney and should know how to conduct herself as a passenger in a car pulled over by police, yet she fails to behave in an acceptable way. Even though certain things may be permissible under certain circumstances, a lawyer should know exceptions and extenuating circumstances, but she apparently does not. She did not have the right to interfere with a police officer and "demand to know" or get out her cell phone to record if she was told to keep her hands where he could see them. (00:10:25)
Plot hole: So when he travels through time whatever he has on him or with him or whatever he's holding goes back in time with him just like his dog or the wood. Now he's sitting on the rock drinking a beer and his friend is talking to him and all that's heard and seen is his beer bottle breaking on the rock when he disappears through time. Makes no sense for it to fall from his hand and break if he's in possession of it. The beer should've gone with him. (01:26:30 - 01:27:30)
Factual error: In 1940 3 of Alf White's men are arrested. As they are taken out of the pub they were in Alf and his son stand in the doorway. To their left (viewer's right) are posters for Floyd Patterson (who would have been aged 4 or 5 at the time) and the Platters (formed in 1952) and Lonnie Donegan (started performing 1949). (00:20:03)
Other mistake: Jesse does not talk because of his traumatic childhood (which includes being kidnapped at a young age by Mr. Charlie), so it doesn't make much sense for him to be the narrator.
Other mistake: Aerial views of Yonder gave the impression that a basic grid pattern was used - parallel horizontal and parallel vertical lines that form right angles; yards were of equal area, either a square or rectangular lot. [However, some of the views from the couple's car as they were trying to find the exit showed some slightly curved roads that didn't fit the grid.] Following the sun as a way out, the couple was jumping over fence after fence - but they could've simply walked along perpendicular roads.
Suggested correction: But they tried getting out using the road by car, and they felt that the roads were causing them to go into a loop. So instead they take a route they know for sure is straight. Btw, Yonder isn't real so the way the roads bend and how the grids are made up is purely an optical illusion.
Walking (not driving) along the perpendicular fences would be the same difference only easier and less exerting. If/when they encountered a fence that looked different, that's when they could jump over it to see if it made a difference. How could they "know for sure" that the fences they were jumping over took them in a straight line? Also, they realised the clouds weren't real, so following something in the sky (the sun) was not necessarily a good idea. [This will be my only response here.].
Continuity mistake: After being buried alive, Wake returns to attack Howard with a pick. There isn't a speck of dirt on him.
Continuity mistake: When 7 (Tom) tells 8 (Molly) to get her metaphors straight, a woman carrying flowers, her hair tied in a short bun, walks by. In the reverse shot, she turns into a different woman with long hair. (01:07:30)
Continuity mistake: At the beginning of the movie, the girl gets assaulted from the back: you see at first exactly from the shot from behind that the backpack she is carrying escapes her arms, but in the subsequent shot she is still holding it. (00:02:10)
Other mistake: Daniel realises that Adereth gave him his own passport. When he looks at it, notice the machine code line; it's the passport of someone born on April 30, 1963, far off from Daniel's age, and more importantly, not matching the ID's date. October 10th 1982. (00:20:30)
Other mistake: Elsa Brecht is holding an official piece of mail sent from the Coconut Grove Hotel in Miami but it's postmarked Orlando, Florida. There's no legitimate reason the mail would be postmarked Orlando when Orlando is 235 miles from Miami. (01:24:16)
Other mistake: Throughout this, a running gag is that Fred can't drive stick/clutch. However, in "What's New, Scooby-Doo?" Series 2, Episode 6 "A Scooby-Doo Halloween," he yells at Shaggy that he's riding the clutch too hard at the beginning of the episode. If the Mystery Machine has a clutch mechanism, he would know how to drive stick/clutch.
Continuity mistake: The way Linda holds her coffee cup changes numerous times, often instantly with front versus rear views. The handle switches (changes 90° or 180°) from facing towards her chest to her left knee to opposite her chest while holding the cup between her bent knees, which vary in distance apart. The cup is held a few inches above, below, or about even with her kneecaps. (00:44:35 - 00:48:23)
