New this week Continuity mistake: When Tintin is investigating Mueller's room, he comes across a file with various articles in it. Before Tintin goes to pick up the file, the articles are on the right hand side of the file, but when he has the file in his hand, in the exact same shot, several articles have immediately appeared on the left hand side of it.
New this week Continuity mistake: When Tintin opens the secret passageway, the fireplace retreats backwards leaving an open gap about several feet wide in the fireplace. As he heads down into the passageway a couple of shots later, the open gap in the fireplace has suddenly expanded much further.
New this week Continuity mistake: After Mueller has caught Abdullah, Tintin shoots the lock off one of the cells and hides in it. When he is inside, the bullet damage from when he shot the lock is visible and is coloured green. A few shots later, the damage is suddenly beige and the same colour as the door. Then a few shots after that, the damage is suddenly green again.
New this week Continuity mistake: After Thomson and Thompson have inadvertently taken the Formula 14, Tintin, Haddock and Abdullah approach them with Mueller. There are oil stains all over one of side of Mueller's jacket and no oil stains on the other side, but after Thompson tells Mueller to get in the car, there are oil stains all over the jacket.
New this week Continuity mistake: When Abdullah opens the cell door, Tintin runs in and grabs Abdullah leaving the door open by a few inches. The shot cuts to the guard that Tintin had knocked out, and the door, visible in the background, is suddenly open entirely. The door has also changed from being grey to beige.
New this week Continuity mistake: After Mueller's car has crashed and Abdullah asks for ice-cream, Mueller replies "Ice-cream?" and we can see his tie is unfastened. In the next shot, Mueller doesn't move, but when the shot cuts back, Mueller's tie is suddenly fastened completely.
New this week Continuity mistake: On the drive back, Tintin looks at the bottle of Formula 14 pills. In a close-up of Tintin looking at the bottle, the bottle is blue, but after Mueller tells Tintin if he destroys the pills he can make him rich, the bottle is suddenly green.
New this week Other mistake: When Mueller is at his desk, writing, a fly comes into his view. Just before the fly appears in view of him, he is writing on his paper, but he is just shown writing in the exact same spot and nothing ever appears on the paper.
Continuity mistake: Whilst examining the wrapper with "Karaboudjan" written on it, the "K" is a centimeter away from the letter "A" and all the other letters are about a fifth of a centimeter away from the letters. Tintin then places a magnifying glass above the word "Karaboudjan". After doing this, the "K" that was a centimeter away from the "A" is now a fifth of a centimeter away from the "A", but none of the other letters seem to have changed distances.
Continuity mistake: When the military police are looking through the detectives' bags, one of them finds a bag that Thomson and Thompson assume to be the secret documents. The man begins to shake it and diamonds fall out. In the first shot of the diamonds falling out, as the shot ends, two diamonds are in the man's hand, followed by a third diamond falling out. The shot cuts and there are suddenly five diamonds in the man's hand, followed by a sixth diamond that falls out.
Continuity mistake: After Tintin realises he was right that the man was Mueller, the shot then pans back to Mueller looking at his face in a small mirror. When the shot stops panning, there is nothing reflected in Mueller's mirror. The shot changes to a close-up of the mirror and Mueller's reflection suddenly appears in the mirror.
Plot hole: Thomson and Thompson fall asleep whilst driving their jeep and are arrested because whilst they were asleep, they drove into and damaged several people's markets and as well as driving into the wall of a building. Although the decision to arrest them would seem normal due to the vandalism, it does not make sense why both of the detectives would have gotten arrested. Even if they both fell asleep at the wheel, only one of the detectives was actually responsible for the vandalism caused by this.
Continuity mistake: Tintin is waiting for his meeting with the Emir in the castle. In the first interior shot of the castle whilst Tintin is waiting, the handle on the left side of the door is slightly lower than the handle on the right of the door. A few moments after Tintin walks into the room, the door closes behind him and the two door handles are suddenly level with each other.
