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)
Audio problem: The chef finally gets the bright idea to fire his hunting rifle at Morgan's fleeing vehicle. In a previous scene he was grabbing ammunition for his rifle, and he also loaded it. The rounds appeared to be high power rifle ammo, probably in the 7mm Remington magnum or .30-06 range, very common hunting rounds. When he fires his rifle it sounds quieter than a suppressed shot, however he has no suppressor on the muzzle end of his weapon. (01:09:20)
Continuity mistake: When Gina and James visit her sister, Gina sits down at the table with the family. Then in a close up with James and Ramon, Gina walks into the same room she should already be sitting in. (00:48:30)
Other mistake: The typewriter ribbon in Gemma Arterton's typewriter looks to be installed upside down, with the red half of the ribbon showing above the black half.
Other mistake: Daniel Blake in the first minutes of the movie is at the hospital taking an echocardiogram. On screen you can see the date of the test; 20/10/2015, so he took it on the 20th of October. The day goes on with Daniel visiting his coworkers, then he is at home, with BBC Radio Four saying it's twelve to 1:00 and broadcasting the first shipping forecast of the day for "Tuesday the 20th." (00:04:40 - 00:06:50)
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.
Continuity mistake: The blood that drips on the girls disappears between shots. (01:06:00 - 01:07:00)
Continuity mistake: The old man in the hotel lobby pulls the flowers out of the megaphone and calls the protagonist. She lowers the headset to talk to him. The left speaker is all the way across the opposite side of the neck in the first shot, less shifted to that side in close-up. (00:04:00)
Continuity mistake: The protagonist is on the couch with his girlfriend in Fresno. He mumbles worried about her dad "knowing"; his hands are joined with different placement (left on top, right on top) between shots. (00:13:15)
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.
Factual error: In the Templehoff Airport flyover scene there are Soviet era Antonov An-12 propeller driven aircraft on the tarmac. These were first used by the Soviets in 1953.
Continuity mistake: Maudie lights herself a cigarette. There are 2 matchboxes on the railing of the porch. They disappear for the rest of the scene and Maudie's cardigan and dress do not have pockets. (00:02:35)
Continuity mistake: Near the end of the film when Robert De Niro gets to make out with the college girl, the switches between camera shots show his shirt off and subsequently back on again.
Other mistake: When Warwick Davis shows Joe the form he's tricked his father into signing to allow him to transfer schools, the form is shown full screen. The "home" phone number is the same as that used in the school's letterhead, and there is text that says"insert name of fictitious school here." Also in this scene the name of the headmaster and phone number is visible, but none of those details match what is on the school's advertising board a couple of scenes later when Joe starts at his new school.
Continuity mistake: When Justin Bieber takes out his phone after being shot, the time on the phone is displayed as 1:48AM, but seconds later, when the camera pans down on the phone before the scene ends, the time displayed on the phone is now 1:51AM. Three minutes did not pass during this time.
Continuity mistake: When they are at Sarah's house, the boy's father tells her to go outside and ask Lucas to pull the van around back. When Sarah walks to talk to Lucas her long braided hair is tucked into her shirt and her arms are crossed. In the next shot when the camera comes back, her hair is on the outside of her shirt despite her arms still being crossed. (00:45:55)
Continuity mistake: Throughout the movie, fire axes seem to be the weapons of choice. Only two fire axes are used, but they appear recurrently. In the very first use, the protagonists grab fire axes to butcher the monster called Beverly. Blood and gore go everywhere; yet, the axes emerge from this bloodbath with no blood or gore on the handles - they're virtually pristine moments later. The axes are used again and again, right up to the ending, and blood comes and goes from the axe handles seemingly at random.
Other mistake: When Drek lands in New Quartu, his crashed shuttle is facing towards the Deplanitizer's direction. His shuttle should be facing the other way since he was launched straight to New Quartu.
Visible crew/equipment: A cameraman is in the bush at the start between the preacher and his mule. (00:01:06)
Factual error: After the death of his beloved pet turtle, Conner is on a downward spiral. One of the headlines that appear as paparazzi follow him (before he gets KTFO'd by Martin Sheen) has a "Friday August 08, 2015" date. Which was a Saturday. (00:58:10)
