Continuity mistake: When the Bellas just got told that they are not allowed to compete any more they walk outside and Beca gets a call. When the camera is zoomed in on her you see her calling and moving a lot. When the camera is focusing on the other Bellas she is standing completely still in the background. When the camera is back on Beca she is moving again. (00:12:50)
Continuity mistake: Charlie Brown is using a pen to write a book report. The black ink leaks and gets all over his hands. When he walks to his dresser to get a pencil, all the ink stains are gone.
Suggested correction: He wipes the ink on his shirt.
Deliberate mistake: While Donnie is training at Front Street Gym, when Rocky repeats, "One step at a time, one punch at a time, one round at a time," the closeup of two children watching from outside the ring is a flipped shot, note the backwards Nike swoosh logo and Everlast ring rope spacer. (00:53:05)
Factual error: The 'Post Office' is nothing like an English one would have been, even in a remote rural location in Victorian times. It seems to have been transposed from the American Wild West.
Factual error: The year is 1952. In an exterior scene, Saoirse Ronan is seen on a street in Brooklyn. In the far background, a red "WALK/DON'T WALK" sign is flashing. This type of sign was only introduced across NY in the late 50s.
Continuity mistake: Spot finds four other humanlike creatures and goes to them. Arlo is standing several feet in front of them. He begins to push some dirt by using his nose. A close-up then shows him using his nose to draw a circle around the five others but he is standing much too far away to be able to do this.
Factual error: There seem to be modern "Walk" and "Don't Walk" signs at each intersection. This film is supposed to take place in 1952. Also it is mentioned there are "Stereophonic" consoles in the motel rooms. Probably would not find those until at best the late 50s.
Continuity mistake: Near to the end Gabriel Oak leaves the farm and as he leaves his cottage he is dressed in a white shirt, cream trousers and a dark waistcoat. When Bathsheba Everdene catches up with him on the road he has completely changed his clothes and is now dressed predominantly in blue.
Continuity mistake: The full table of scores for the contestants is visible before the Carl Hayden High School students actually did the task (they were the last group to do it). (01:25:20)
Continuity mistake: In the early scene, when Maura is talking to the man in the corner, that she thinks is homeless, she stands up and has a green bag on her shoulder. When she asks for the sunscreen back, there is no sign of her bag. Then it's back on her shoulder.
Continuity mistake: The getaway car changes from a Peugeot Partner (1996-2003) to a Citroen C3 Picasso (2013-2017). (01:35:30 - 01:36:05)
Continuity mistake: When Albright's driver is taking Mark at gunpoint to the car (after leaving Mrs. Jensen's room) he has his gun against Mark's chest, but in the next shot it's against his back.
Continuity mistake: When Shaggy and Scooby are approaching the Demon as he eats, it is shown that he is eating from a platter of hamburgers and french fries. Scooby and Shaggy bump into his table, knocking the food all on the floor. When Shaggy and Scooby quickly put all of the food back on the table, it now has french fries and hot dogs.
Factual error: Herman Melville interviews whaling survivor Thomas Nickerson in Feb. 1850. Nickerson tells him "I heard a man from Pennsylvania drilled a hole in the ground recently and found oil." Oil was discovered in Titusville PA in 1859.
Revealing mistake: When Krampus walks toward Max after he yells at him to give him his family back, wires are controlling Krampus' arm. (01:24:30)
Plot hole: They have to invent Nitrotrinadium when they travel to the future because it was not invented yet, but was in the Russian drink in 2010, so should have already been available when they travel to the future.
Revealing mistake: When the twins are born neither baby has an umbilical cord attached to them. Also the baby girl has a bellybutton.
Continuity mistake: When Tris saves Christina from falling and then rolls on to her back you can see her sports bra underneath. In the next scene, she and Tobias have a brief sex scene where she removes the same top, but there is no bra underneath.
Revealing mistake: Right at the beginning of the film "rain" is falling on the car the camera shows before it moves to focus into the tunnel. However, look at the cars behind it, they aren't wet at all and it's visibly sunny. It's water being poured onto the car directly in front of the camera.
