Factual error: Winter in Antarctica would not have a night and day as portrayed, with the amount of light changing so much during the course of 24 hours.
Factual error: When Nate dies by the alien moon rocks, his helmet visor "explodes." The visor in the film shatters like glass, but the real visors on actual spacesuits are made of polycarbonate, a plastic that does not shatter but deforms.
Factual error: In the scene where Olivia's body is being removed from her home. Olivia was covered in blood, yet the sheet covering her has blood only in her chest area. The sheet would have had way more blood on it. Also, I'm an EMT, sheets are not used on victims that are dead. A body bag that zips closed and is made of rip proof plastic is used to transport deceased victims (especially if they are as bloody as Olivia was supposed to be). White sheets on a corpse are only seen in the morgue. (00:40:00)
Factual error: The Song "Looking for the Magic" by the Dwight Twilley Band plays on repeat several times throughout the movie, however it comes up as track 1 on the CD player each time."Looking for the Magic" was never the first track on a Dwight Twilley CD - It was track 2 on the group's 'Twilley Don't Mind' album released in 1977. You can tell the disc is not a homemade mix CD by the printing on the top of the CD the first time it is placed in the tray.
Factual error: During the sleepover in the tent Dennis gives the girls M&Ms to snack on. If you look closely you can see one of the girls eating a blue M&M. These didn't hit the market until around 1995, a full 7 years after this movie takes place.
Factual error: In Sam's premonition, when Isaac is still in the bus when it is falling down to the water, he is at the front of the bus. In reality the falling force should be pushing him to the back of the bus.
Factual error: The character Peter has a modern haircut that would not have been found during medieval Europe; his hair defying gravity despite being a time without hair gel.
Factual error: During the end where the girl gets her phone back she has a text. However inside a submarine with the hatch shut there is no way for a mobile signal to get through.
Factual error: Colonel Meyer's promotions are listed in his SS ID card as Hauptmann, Oberstleutnant and Oberst. Since the SS used a different ranking system from the Wehrmacht, they should actually be Hauptsturmführer, Obersturmbannführer and Standartenführer.
Factual error: Jerry digs up a natural gas pipeline in the backyard and jerks it so hard that a pipe coupling in Charlie's house breaks, venting natural gas into the house for about 4 seconds. Then Jerry uses a cigarette lighter to send a flame through the pipeline, exploding Charlie's house like a fire bomb, catching virtually every room in the house on fire. In reality, it would take an hour or more for vented natural gas to accumulate sufficiently to blow up a house, for one thing. For another thing, Jerry broke the gas pipeline in the backyard in order to ignite it; so, while the broken pipeline leading to Charlie's house had no gas pressure, the pressurized side of the pipeline was still in the backyard with Jerry. Meaning, Jerry himself should have been engulfed in fire as soon as he sparked a flame.
Factual error: In his crude attempt to replicate the Human Centipede surgical procedure, Martin employs several handyman tools, including a carpenter's staple gun (using T50 staples as sutures). Problem is, carpenter's staples would never join soft human body tissues, they'd pull right out with little effort (T50 staples only join to very solid base materials, such as wood). Martin's victims, hysterical as they were, could have freed themselves from the T50 staples almost immediately.
Factual error: The young priest sees images of a red-eyed horse, but later, it is referred to as a mule, which looks much more like a donkey.
Factual error: Mallory tells Florence that the school is in Cumbria. Cumbria didn't exist in 1921. It was created in 1974 from Cumberland, Westmorland and part of Lancashire.
