Continuity mistake: After Emily burns her home it's night time, then she follows the police cars and it seems like evening, and when she comes out from the water the sun shines in the background.
Revealing mistake: Axel's badge says deputy sheriff. He is THE sheriff. Not a deputy.
Continuity mistake: The first time we see the zoom on the digital watch on Gabriel's arm in the vault, it's counting up the time. Next couple of times we see the watch, it counts down the time. (01:04:35 - 01:05:35)
Factual error: When Robert Bingham is shooting at Cal, an MPD (Washington, DC) squad car shows up. However, the scene is set in Crystal City in Arlington, Virginia, outside of MPD's jurisdiction. Arlington County Police would have responded instead. (01:13:05)
Factual error: In the scene where Tucker is talking with Hugh Hefner, the chess board in the background is set up backwards. The pieces are basic Stanton style, and the kings and queens are obviously in the wrong positions.
Factual error: During the surgical operation, Dr. Heiter makes incisions on the buttocks for the triangular flaps of connecting flesh; but the flaps are pointing outward, rather than inward. The only way to graft the buttock flesh to the face of the next subject would be with the buttock incisions pointing inward.
Visible crew/equipment: At the start of the scene where Evan is racing to the school to get to the choir, you see some buildings. If you look down when the angle is turning to the right, it focuses on some cranes, a camera, and a wire holding it up, and a crew member is visible in the reflection of a red window.
Revealing mistake: It's an obvious rubber dummy when Chavez cuts off Juarez's leg. (00:43:30 - 00:44:05)
Continuity mistake: When Jane is crying and staring at the sky she is not holding a napkin, as the scene cuts back she is.
Factual error: Two of the albums sent to Larry by the Columbia Record Club are Santana's "Abraxas" and Creedence Clearwater Revival's "Cosmos Factory". The film takes place in 1967. Both albums were released in 1970.
Factual error: Contrary to what the movie states, priests can be elected Pope - they are simply elevated to the rank of Bishop before taking the office.
Suggested correction: Him being only a priest was simply an excuse not to elect him. Those who did not want him to be pope were trying to find any reason to keep it from happening.
Any baptized Catholic male can be elected pope, although it has only happened once. Pope John XIX in the 11th century was a layman, ordained after his election.
Revealing mistake: After Chuck steps on the toy duck, he looks up to see the alien family and their house behind them. However, there is no reflection of this on his visor, just an empty field and the trees beyond.
Continuity mistake: In the carnivorous plant scene, Manny grabs the fruit (the bait), which is sitting in the middle of the plant. In the next few shots, the bait disappears and then is replaced with a bulb that housed the red and blue "wires".
Continuity mistake: After Esther suffocates Daniel in the hospital, Kate slaps Esther in the face. The hospital staff then hold down Kate and she drops her iPhone, screen down. The iPhone starts ringing, even though the screen is facing the floor. In the next scene, it is still ringing, but with the screen facing upwards.
Factual error: After James leaves the bar and is driving, you see a dealership in the background and you can see new trucks and a new model yellow mustang. The movie takes place in 1987, so the vehicles are about 20 years too new. (01:26:00)
Continuity mistake: In the scene where Clouseau is having his hair shampooed, the amount of shampoo on Ponton's hands changes, and then the suds disappear. (01:07:40)
Factual error: When Sam speaks with his daughter on the long range phone there is virtually no delay between some questions and answers. It takes over two seconds for radio waves just to travel from the Moon to the Earth and back in a straight line. The interval between question and answer physically can't be shorter than that and realistically should be around 3 seconds or even more, accounting for additional signal relays and time needed for a person to form a statement. Same for the communication between Gerty and the Lunar employees when Sam 2 got out of his infirmary bed.
Continuity mistake: When 9 meets 3 and 4, they open his zipper. During this scene, several close-ups show 9 with the zipper closed and open again without anyone closing or opening it.
Other mistake: When the mayor is talking behind the chainlink fence, with Brent in the background eating sardines, you can see as the mayor grabs the fence, his thumbs clip through the fence wire. This occurs on both hands and easily visible, particularly when Mayor Shelbourne says, "Otherwise, I'm just a tiny mayor of a tiny town full of tiny sardine-sucking knuckle-scrapers." (00:10:52)
Suggested correction: I watched this movie a million times and the mayor's thumbs are not going through the fence.
Then something's wrong with your eyesight, because it's very easy to see.
Factual error: After they finally start spending money, and after you see them in the older model black Mercedes Benz S-Class, you see clearly a newer model silver Chevrolet Corvette ('05-'09), even though the scene is supposed to be taking place during the latter part of 1996 or early 1997.
