Continuity mistake: In front of the station, the con man bargains with the taxi driver the fare; during the scene, the same black man with a floral shirt passes at least 3 times. (00:01:30)
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)
Factual error: When Vinny Panzienza has his cervical halo brace removed (without anesthetics), he yells and groans and grunts in pain, but his hands are relaxed on the arms of the chair. I can tell you, from experience with this exact situation, the pain is so intense that his hands should have been clenched as tight as a vise.
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: The protagonist is fondling his pregnant wife in bed when she pinches his nose. Between the two shots the blanket covers /uncovers the baby bump, and her hair is bunched on the pillow in entirely different ways. (00:01:40)
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.
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.
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)
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 Lady Susan is counseling her daughter Frederica in her bedroom, the shot shows an unlit candle on a dresser behind Lady Susan. The shot changes back and forth between Frederica and Lady Susan. When the shot changes back to Lady Susan, the unlit candle is gone, though there is no one else in the room.
Continuity mistake: Mikey dropped the wristwatch Andrew gave him and it landed face down with the bands upward. When Mikey jumped off the rock to retrieve it, the watch's face was on its side (visible to the screen) and the bands were parallel to the ground. (00:05:04)
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)
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)
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.
Continuity mistake: John Biswas is tailing the little deaf girl. His scooter breaks down and he follows her on foot. They are walking in the same road in two different shots, with a cut just a few meters apart. The toys in her right hand and the paper in her left swap hands in the second shot. (00:18:20)
Continuity mistake: The main character is chatting with Harper at the shooting range. Harper's earbuds and protective goggles change position between shots throughout the scene. (00:08:50)
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: The crew arrived at the volcanic island in turmoil, and are talking with the local captain. The captain asks them to carry also some of the dead people, and they start asking him what the plan is, if there's one at all. The pass at the neck of the captain shows the side with the symbol in one shot, the blank one in the next. (00:25:10)
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)
