Stupidity: Sherlock Holmes, a "simple" detective, knows the whole story of an English officer and that of a Nazi secret agent and their great physical resemblance, but Barham's colleagues in British Intelligence do not know any of these facts and are surprised when Holmes tells them all the details.
Stupidity: How would a devout catholic like Angela not believe in the devil, as she tells Constantine? Makes no sense.
Suggested correction: Some Christians don't believe in the literal personification of the Devil. They see him more as a metaphor for all human sins. So according to them, the Devil is not something to blame evil on. Everybody has God and the Devil in them.
Stupidity: Why does a safe house have a skylight? It is a secure building with hardened doors but a window in the roof?
Stupidity: They have the technology to track the movement of the rebel troops, and while the Nigerian airspace is too hot for extract, the fighter jets landing behind Tom Skeritt on the carrier could easily wipe out 300 rebel soldiers.
Stupidity: The first time they see the bad guy in the Land Rover, Morgan has him in his sights but can't shoot, as he doesn't want to kill him. Clearly, the obvious thing to do is to shoot the car tires, but he doesn't and lets him drive off.
Suggested correction: Shooting out car tires is not an actual effective strategy to get a vehicle to stop. A 9mm bullet simply doesn't cause enough damage to a tire to get it to go flat immediately. It causes similar damage as running over a nail. It is a movie cliche, similar to using a gun to shoot out a lock or a rope, it just doesn't happen in real life.
Stupidity: At the end of the film, Abel had nothing to gain from lying about having a gun to the police officer. He had no way to prevent Chris and Lisa from presenting the informant's cell phone and exposing his involvement in the break-in and vandalism of the couple's house. Additionally, testing from the shots fired in the house and the car would prove that there were two different guns involved. As a long time police officer, Abel should have known that giving up the gun would have been the easier way out instead of lying about it.
Stupidity: After suturing the woman's gunshot wound in the barn, the Virtuoso finds a space heater. He sets the space heater on top of a low stand of some kind and then uses an extension cord to plug it in - two things that should NOT be done when using a space heater. Also, there is sound as though the space heater is running, but there is no change in color (coils turning red) that would indicate it is on and heating. (01:12:44 - 01:13:06)
Stupidity: Glenn's house is next-door (with not much space between) to Susan's. Christina's bedroom window is opposite Henry's bedroom window, but both 11-year-old classmates do not close their curtains (leaving space in the middle between the panels). Furthermore, Police Commissioner Glenn Sickleman - suspected of abusing Christina - does not bother to close Christina's curtains when he goes into her room to abuse her! This enables Henry to suspect (possibly KNOW) that Glenn is abusing Christina. (00:18:20 - 00:19:06)
Stupidity: When one of the robots gets stuck in the cave, the group moves past it and doesn't bother to try to disable it or take its weapon. A trained Navy SEAL would never leave an enemy combatant just lying there with its weapon within reach.
Stupidity: At the end Vince fires a grappling hook at the passenger seat of the truck then attaches the other end to himself, all the truck driver has to do now is hit the brakes and Vince would be dead under the truck or dragged along the road.
Suggested correction: In point of fact, the truck driver does slam on his brakes; but, defying physics, Vince is catapulted around the right side of the truck to the passenger door.
Stupidity: Patrizia Reggiani is no rocket scientist in this movie, but it's quite bizarre that calling the fortune-teller she sees on TV, with her name written in giant letters in two different spots on screen, she asks her "What's your name?" It makes sense for the international audience who may not recognize the word "Pina" as a name, but an Italian wouldn't have any doubt. (00:41:05)
Stupidity: Carl buries the case with the money in a field by a fence. He looks at the fence line and wonders how he is going to be able to find the spot when he returns. He plants an orange ice scrapper to mark the spot. The scrapper is only 6-8 inches, but it's the middle of winter in Minnesota. The scrapper will be buried by snow. He should have marked the spot by tying something on the fence. (01:18:26)
Stupidity: When the two Russians are walking past the security guard after killing Gregor, they are just allowed out without being detained because one of them shows a Chilean passport. The French gendarmes are not that incompetent. They would detain the men until everything is (or is not) cleared up. (01:49:05)
Stupidity: The kidnappers steal a silver Citroen van and take it to a junkyard to switch the plates. They steal plates off an older green color Asian type sedan and place them on the van. If the cops run the plates as they normally do random checks as they drive, those plates will not match that vehicle. They should have found the same make and color of Citroen van they stole and swapped plates for plates, the chances of the owner noticing are small. Now if the plates get run they match that vehicle. (00:00:38 - 00:01:18)
Stupidity: There is a scene in which the phone rings back at the house and Andy goes to answer it. None of the henchman respond immediately, but instead WAIT for him to almost answer the phone before becoming making a move. You would think they would yell at him to not answer it or have one of them rush to guard the phone the moment it rings. Obviously the entire scene was done this way for the sole purpose of suspense.
Stupidity: Jimmy parked his truck on the side of the road with woods running parallel and starting about 10' away. Jimmy moved to the passenger side so the Sheriff could sit in the driver's seat (for no apparent reason). After Jimmy threw the "white powder" into the Sheriff's face, he quickly got out of the truck and ran straight ahead on the road instead of ducking into the nearby woods. The Sheriff had a clear and easy shot to hit and kill Jimmy. Also, Jimmy should have been much further away. (00:11:51 - 00:12:21)
