Deliberate mistake: The Virtuoso (up several stories in a building) would not be able to hear what the boy and his mother across the street were saying. The boy even started to say "Hey, mom" when he was still exiting the building. (00:11:41)
Deliberate mistake: When Casey is hiding behind the boxes waiting to knock out a Foot soldier and steal his outfit, you can see he is still wearing his denim vest. After he knocks out the Foot soldier, he is able to put on his entire outfit in roughly three seconds. (01:10:15)
Deliberate mistake: The thug wearing headphones and facing the money on the shelves did not notice that Savage forcefully opened the door several feet to his right, slamming it against the adjacent wall, or that Savage had entered the room. The bang to and vibration from the door hitting the wall should have been enough to overpower the sound from his earphones, but - even if they weren't - his peripheral vision should have sensed the door opening and Savage entering. (00:02:55)
Deliberate mistake: In Silence of the Lambs Starling was right-handed. In Hannibal she is left handed because we see her writing with her left. Julianne Moore, the new actress who plays Starling is left handed whereas Jodie Foster was obviously right-handed.
Deliberate mistake: The F&F series always shows some amazingly advanced (and unlikely) technology; in this movie there is a big usage of electromagnets that are nothing short of miraculous. Not only they have a strength that would require them to have generators tens of times bigger than the cars they are on, and repel with the same ease as they attract; they also attract objects with varying° of precision and direction, all by turning their simple dial.
Deliberate mistake: To meet Manny, Mike walks through his store. The last obstacle is a PVC curtain. The camera has to go through the curtain, moving it and thus revealing its presence. However, it is definitely a deliberate artistic choice. (00:32:50)
Deliberate mistake: Where are the motorcades for the other world leaders?
Deliberate mistake: The front passenger's side mirror [driver's side is on the right] is parallel to the screen/camera yet there is a perfectly clear image of the passenger's face looking into the mirror. (00:00:38)
Deliberate mistake: Ryan was cooking venison (deer meat) in a pan over hot coals. He speared a piece with his knife and held it up for his young son, Billy, to take, which Billy did with his fingers. But did not get burned or show any signs that the meat was hot. Billy was even able to take a bite of the meat. The meat could not have cooled off that fast, even outdoors in jacket-wearing weather. (00:07:04)
Deliberate mistake: One of the bodyguard's rifle which is a Sig model SG553 only has a front sight and no rear sight. The rear sight can easily be attached to the Picatinny rail. Such a rifle is only good for up close instinctive shooting, anything at distance is spray and pray. (01:39:00)
Deliberate mistake: In one of the scenes where Johnny Depp goes into the bathroom (specifically, when he changes clothes with the other man), Christopher Walken's character looks under the stall. The camera then shows the legs and crotch of a man sitting on the toilet, who still has his boxers fully on, but his pants are down.
Suggested correction: That man was not actually using the toilet. He was posing as Watson (Depp) so that Walken would think he was in the stall the whole time.
Deliberate mistake: How does Lisa appear resplendent in that perfectly smooth wrinkle-free negligee when we saw it earlier all stuffed into her overnight bag?
Deliberate mistake: During the song Adelaide's Lament, Adelaide goes to her medicine cabinet, opens it, and there is a cut to a shot from "inside" the cabinet as she surveys all the medicine she takes to treat her "cold." From the inside, the cabinet is almost twice as wide as it is when it shows her open and later close it from the outside.
Deliberate mistake: When Dooley looks at the photo of himself, Jerry Lee and his wife Tracey, it's obviously a still shot from the first movie, as the angle the picture is taken from was obviously not taken by anyone else as they were the only two in the apartment with Jerry Lee at the time. (01:11:40)
Deliberate mistake: During his autopsy in Saw IV, it is revealed John Kramer was 52 at the time of his death. Kramer's role in this film is the very early stages of his time as Jigsaw, shortly after his cancer diagnosis, which would put him in his early 50's. However, he looks far too old to convincingly be that young (Tobin Bell was in his mid-70's at the time of filming). He even looks older than he did when he was on his deathbed in Saw III.
Deliberate mistake: Frequently during the movie, British surgeons are referred to as "Doctor". In Britain, surgeons are always referred to as "Mister"; this is a hold-over from the surgeon's non-medical past (barbers, etc). This would likely be confusing to American audiences.
Deliberate mistake: Declan and Preston are hanging out at an airfield in a blue car when they realise one of the numbers in the notebook they have is an FBI access code that The Jackal now has. In establishing shot of this scene you see the blue car sitting more towards the left with Declan on the hood. Then when Preston calls in this finding and they get a helicopter to come pick them up, in the shot with the chopper coming the car is now suddenly much further to the right. It seems they had to move it during filming to allow a place for the chopper to land. (01:19:05 - 01:20:30)
Deliberate mistake: During the fight at the Unity Day Festival, at one point Goblin is confronted by some cops and beats them up. Watch closely... you can tell that the first and second shots are just different takes of the same stunt from a different camera angle. Goblin's movies are exactly the same (except slightly faster in the second shot), and you can also tell it's the exact same two cops he's hitting. They tried to artificially lengthen the scene by showing two slightly different takes of the stunt.
Deliberate mistake: Poirot riles up Pennington narrating the story of Grand vizier Ptahhotep who was crushed under the weight of the silver he embezzled. It's a lovely moral story, but Ptahhotep was actually a virtuous administrator and is credited (with various caveats) with writing "The Maxims of Ptahhotep", one of the first books in human history, and there's no record of such a story. It's likely that Poirot made that part of the story up counting on Pennington's ignorance on the subject. (00:44:20)
Deliberate mistake: The driver's side mirror would not be able to capture the view of the store that Monique is robbing - the mirror is slightly angled towards the rear of the car, plus Arthur's car is parked too close across the street. (00:00:33)
