Factual error: Whenever they open the trunk of the Eldorado, it acts and sounds like there is a push button. In fact you have to use a key to unlock and open the trunk.
Factual error: The horn on the LT's Range Rover is at the end of the signal lever not in the middle of the steering wheel as shown.
Factual error: When Judith wakes up chained to the engine block she notices the Sony camera on a pole. The guys are presumably watching her through that camera. The problem is that there are no cables running from that camera to provide the video feed to the TV. Sony cameras always have the video output connections on the front right hand side. There are no cables attached to this camera. (00:35:40)
Factual error: When Corky is trying to get into his family's underground casino and is being worked by the wrestler girl and the "little person", his wallet falls out. The little guy picks it up and looks at his license. The next shot shows you the license is from Florida and this license number starts with an "L". That is incorrect because in Florida your license number always starts with the first letter of your last name. In Corky's case the letter "R".
Factual error: The bank Steve Coogan wants to rob is in Manchester. When he sees the bank for the first time, we see a CMT bus drive past behind him. CMT buses operate in Liverpool, not Manchester.
Factual error: In the end where Larry and Brian are sitting in the garage, one of them is watching a hit counter for their website, and the other is watching the news stream on the computers. When the reporter is walking up the driveway, she mentions that the site has had 18 million hits.. how did she know this? The SkullBocks server was inside the garage, so the reporters couldn't have checked before hand. And even if there was a counter on the website, they were getting 400 hits per second (1,000,000 hits takes 41 minutes). Assuming they looked at a counter, before the reporters left, it would have been a lot less then 18 million. In addition to this, when they open the garage door up, another reporter asks "How many hits have you guys registered?"
Factual error: In a short scene, Sissy Spacek is seen walking down the sidewalk with a 16 ounce cardboard cup of coffee with a cardboard cup holder. The film is set in the mid 1980s, well before regular people walked around with coffee shop coffee in a cardboard cup.
Factual error: When Farva is talking to the Rookie about country music awards, Farva lights a cassette tape on fire. The flame would not spread that quickly.

Factual error: The Kiss of the Dragon acupuncture point, known as "Point 15," is in a delicate area of the spinal column, a little below the second cervical vertebra. It's a definite knock-out target in fighting, and it can even be a lethal target. But Jet Li's explanation that it somehow prevents blood from flowing away from the brain is pure nonsense.
