Factual error: In the opening scene that shows San Francisco scenery there is a shot of a large TV tower called Sutro Tower. The film takes place in 1960 and Sutro Tower wasn't built until 1973.
Factual error: During the credits, as the house is shown, a paper wasp nest is shown hanging from the eaves. Crawling all over it are honeybees, which do not live in paper nests.
Factual error: In some of the shots where the cook is making meth, he is smoking cigarettes. The chemicals involved in making meth are so flammable that if somebody even walked past the room smoking, it would have exploded.
Factual error: After the cops respond to the domestic disturbance (son hitting mom), we see the male officer get in the back with the boy to show him the crime scene photos and he shuts the door after getting in. Police cars are designed so that the back doors must be opened from outside, however, he exited the car with no help. (00:21:00)
Factual error: When the group discovers the armoured truck in the woods, the officer says it's from the 1950's. After they open the door and are looking at the money, it looks brand new. Money sitting in the weather and heat would get mouldy and deteriorate after 50 plus years
Factual error: When Sweeney is sharpening his blades, most noticeably during the shaving contest, he is sharpening toward the blade, which you simply can't do with a razor blade and leather strop. A razor will slice right into the leather. He also doesn't even have the blade flat to the leather so again they're not remotely sharp as a sharp blade would easily sink right into the leather. Pirelli is using roughly the correct technique, even though they're trying to portray him as sloppy. (00:35:50)
Factual error: When they are in Costco there is music playing in the store. Costco does not play music in their stores.
Factual error: We learn that the previous sheriff, Charlie Wade, took revenge on anyone who smuggled illegal immigrants across the border in the late 1950s - we are shown the smuggling, as Eladio Cruz hides a group of Mexican men in a watermelon truck to take them across the border. However, in the 1950s, the border was not fortified the way it is now - the smuggling shown would simply not have been necessary.
Factual error: Several characters can be seen playing an Xbox game console, which was not released until 2001, although this movie is set in 1999.
Factual error: In the scene where Kananga's henchman Adam is being interrogated by Sheriff Pepper by his car at the riverside, the boat chase arrives and two boats jump clearly over head disillusioning Sheriff Pepper and allowing Adam to make a quick getaway. However, as Adam is getting away in his car, screeches can be heard coming from the tyres, but they are on a dry dirt road.
Factual error: Although you'd have to actually live in Boise to catch the myriad of differences from the movie town, the most glaring is that the movie Boise appears to be a lush rainforest, like Vancouver or Seattle. The real Boise is strictly desert, and you won't find those green interstate medians anywhere near here.
Factual error: At the very end of the movie, the Pope gives the nuns a standing ovation. The other people seated in the box with him should have immediately risen at this time. Instead, the man seated to his left looks up at him, seeing that the pontiff has stood, but makes no movement to join him on his feet.
Factual error: In the scene where the Learjet takes off the jet starts to roll. Then there is the shooting with the SWAT team, towards the end of the shooting the pilot pushes the power levers forward to accelerate. Regarding the short take off run they had on the bridge, the pilot would have stayed on the brakes until the engines were at full thrust, then released the brakes, started rolling and wouldn't touch the power levers until after liftoff or in emergency.
Factual error: The time period of the film is 1932. In the opening title sequence, you see someone playing with Crayola Crayons (I assume it's Scout). One of the Crayons is labeled "Melon". Binney & Smith didn't sell the Melon colored crayon until 1949. Crayons produced from 1903 to 1948 sold for a nickel and contained only eight colors: red, orange, yellow, green, blue, violet, brown, and black.
