Character mistake: In his opening prologue, Burt says the Graboids have been contained to the Northern Hemisphere, showing a map highlighting the Graboid attacks of the first film in Nevada and the second film in Mexico. However, it overlooks the Graboid/Shrieker attack in Argentina, in the Southern hemisphere, shown at the beginning of Tremors 3, an incursion Burt personally put down. It's not like it was classified - characters in that movie talk about it being reported by CNN, and characters in the Tremors TV series talk about it as well. And it's not like Tremors 3 is no longer canon, since Burt makes two references to being swallowed by the Graboid in that movie (which also becomes a plot point in Tremors 6).
Visible crew/equipment: When Davis comes out from the train with the headphones on in the subway just before starting to dance, a cameraman filming the scene can be briefly seen reflected on the train door's glass. (01:08:00)
Continuity mistake: In the locker room scene after Tony injures his knee, Tony walks outside the room crying and he then throws his helmet against a wall, causing the chin strap to fall off onto the floor in front of the the doors. When the coach walks in through the door, the chin strap has disappeared. When the coach and Tony hug, look just behind the coach's right arm. You can see a quick glimpse of the chin strap back on the floor where it was before.
Factual error: Bell's father was said to have been heavily in debt while establishing his business. He didn't establish the business. His father did. He inherited it.
Factual error: There are several scenes in a field of barley. Tramlines are seen. Tramlines in crops were invented in 1975 to allow tractors and sprayers to drive up and down fields. Sunset Song is set around 1914, 61 years before tramlines were invented.
Character mistake: The protagonist is reading the review of his book "Bitter Tulips." The influential literary critic publication apparently has zero proofreading, since the article says that the novel "can be described as AN failed experiment." (00:45:00)
Continuity mistake: Right at the beginning of the movie, the Sergeant pulls his jeep over and headbutts a prisoner who is carrying a Danish flag, seizing it. In the following shot he has his arms open and shoves away another prisoner, no flag in his hands. Next shot, he's standing by the bleeding prisoner, folded flag in hand. (00:02:25)
Factual error: Dev Patel is standing in front of Trinity College's statue of Issac Newton. Directly behind the statue is a marble wall with names carved into it. This wall is a list of the members of the college who died in World War II. It would not have existed in 1914.
Continuity mistake: After the disastrous double date, Claire is home drowning her loneliness in alcohol. As she gets in front of the couch, she puts the hair tie on the side table, undoing the ponytail. When the shot changes though, and does it in perfect continuity of position with her just laid feet up on the couch, the hair is back styled in the same tail and definitely tied. (00:19:15)
Continuity mistake: When Carlos goes back to Lacey's home, when she opens the front door she is wearing a long beige cardigan and a green coat. In the next shot where she hugs Carlos she is no longer wearing the coat. (01:47:45)
Continuity mistake: Charlie's mock trial: the latina maid walks up the stairs, with Sebastian saying "OhmahGod, thank you." In the foreground, London is holding her goblet with her right hand, but in the next shot she has it in her left. (00:05:15)
Other mistake: In the break-in lab scene where the characters attempt to film their second resurrection, Zoe has her right hand on the electrical circuit breaker. After she throws the breaker and is electrocuted, Frank after unsuccessfully trying to revive her removes her wedding band, which shows clear burn marks on her ring finger of her left hand. (00:32:00)
Factual error: The girls missed the bus for the football match because one of them got stuck. Luckily they manage to stop a passing truck and ask for a lift to overtake the bus, which, they stress, was bringing the girls "to Trabzon." When their custodians see them cheer on TV and drama ensues, the match is Galatasaray (GS) vs Trabzonspor (TZS); the home team is Galatasaray, so they should be playing in Istanbul. (00:27:30 - 00:29:30)
Factual error: Summer and Carmen are at the saloon and catch on the local news the report of the kidnapping. The scene is set in Tuscany, Italy, but the news anchor is Spanish actress Paz Vega, speaking with an obvious accent and mispronouncing words. To make the whole situation even more absurd, she is supposed to portray a native Italian speaker, "Giulia Carni": the last name is Italian sounding but nonexistent in reality, and the headline used for the news report, "Nonna-napper", "kidnapper of grandmother" has such an awkward and unnatural sound and feel in Italian and for an Italian audience, that nobody ever would use it. (00:37:50)
Continuity mistake: During the assault on the police station, detective Redman shoots at the bad guys from his office door. The bad guys shoot at him too and we see bullet holes appearing on the corner of the door labelled "S10". A few seconds later Redman shoots again, then protects himself in his office, and the corner of the door is undamaged. (00:44:00 - 00:46:00)
Revealing mistake: In one of the opening scenes the platoon of the captain is gunned down by a MG42. You can see the crimped fronts of the blanks in the belt.
Other mistake: Whilst the main character is having a 'talk' with the general, the world clocks on the way show 3:50 on time 1, and 3:49 on time 2. (01:25:10)
Continuity mistake: The guys pass 3 women walking on the sidewalk just before the Ciel pulls up at the hotel to visit Travis. 2 of these women are in the next shot where Vinnie and Eric get out of the car and walk into the hotel. The tall one in a floral dress walks away from the camera and stands to one side, and the blonde wearing the black top and spotted shorts is chatting in the background. (01:06:05 - 01:06:55)
Continuity mistake: When Nicolas Cage is standing on a roof top patio with the oil industry financier, an orange disappears. The oil guy is peeling an orange as he talks to NC and then when Cage leaves the scene the orange is gone without it ever being eaten or discarded. (01:00:00 - 01:05:00)
Continuity mistake: During the fight in the garage, the protagonist neutralizes (and maybe neuters) one of the baddies crotching him with the car door. In that sequence, his hands keep changing position on the door. (00:07:30)
