Other mistake: Even though the building is said to not have power and the guards have to use flashlights, the first time Keiffer goes in the basement he is able to flick the switch and turn on the lights.
Other mistake: After the avalanche when the yetis are pulling the people out of the snow the first person they pull out is by a house or shrine, as they pull them out look closely at the wall right behind them--the "snow" flips up like paper.
Other mistake: Virtually all the text in the various articles and reports in this movie are fake. Look at the John Kramer article at the very beginning, even at first glance you can tell it's an article about pilgrims or something and has nothing to do with John Kramer. Also, when Staham is going through the articles he found on Hoffman's sister, you can very plainly see that every article (there are a few) is just the same typed out story copied and pasted into various formats. (This doesn't even require slow motion, just pay attention.) (00:11:45)
Other mistake: When Bella meets Edward's family, Esme's (Edward's mother) upper forehead (near her hairline) has no makeup, but the bottom portion does. You can see the difference between her pale vampire makeup and her natural skin (which is also shiny).
Other mistake: The ice cream in the film doesn't melt despite being in a room with a fire and several candles.
Other mistake: It is crucial to the story that Peter is terrified of moths - but when he is led through the woods at knife point by Tracey, a large moth flies around both their heads for several seconds (lured by lights of the film crew) and he ignores it, being as it's an unplanned visitor. (00:42:30)
Other mistake: When Oskar finds the solved Rubik's Cube it cuts to a shot of Eli sleeping, wearing a large shirt/dress. However, this shirt/dress is the same one that she takes from Oskar's mother's closet later on in the movie and therefore, she wouldn't have it yet.
Other mistake: At the beginning of the song "Bloodbath", the newspaper that The Graverobber is holding is headlined, "GENECO IN OPERA FUED". (01:07:35)
Other mistake: In the beginning of the movie, they're driving a red car and they crash. Then the police come and they drive away in a black car. There was no scene with a visible towing truck or anything. Did they forget to include them switching the cars or did they make an error of switching the car from red to black?
Other mistake: Jon's vehicle does not have the front license plate that is required in California. (00:57:23)
Other mistake: Misspelled word; "Complilation" on the on screen text. (01:34:50 - 01:37:00)
