The Castafiore Emerald: Part 1 - S3-E7
Revealing mistake: When Castafiore is showing everyone the Castafiore emerald, after she says "He named it in my honour", the shot cuts to a close-up of her hand, saying "The Castafiore Emerald." At the start of the shot, she has two rings on two fingers, then she turns her hand and the two rings vanish from her fingers entirely. (00:09:00)
The Castafiore Emerald: Part 1 - S3-E7
Revealing mistake: When Castafiore locks her jewels in the drawer, she places the key inside the lock, but the key visibly surpasses the edge of the lock. (00:10:00)
The Castafiore Emerald: Part 2 - S3-E8
Continuity mistake: When Castafiore is complaining about the stairs not being fixed, the first shot of her shows nothing on the torso section of the dress she is wearing, but when the shot is on her next, a small design has suddenly appeared on the chest area of her dress. (00:24:55)
The Castafiore Emerald: Part 2 - S3-E8
Revealing mistake: When they are watching the news broadcast on Calculus' high definition television set, after the news broadcaster mentions Castafiore's stolen jewel, Castafiore says "He's talking about me." The mole on her cheek appears and vanishes from her face whilst she is saying the line, revealing a slip-up in the animation. (00:35:00)
The Castafiore Emerald: Part 2 - S3-E8
Revealing mistake: After Calculus has finished the high definition television broadcast, Tintin and Snowy are lying on the grass. When the scene starts, a bird is shown flying into frame and continues flying, but whilst it is on-screen, the bird suddenly vanishes from the frame. (00:36:30)
Destination Moon: Part 1 - S3-E9
Continuity mistake: When the car taking Tintin, Haddock and Snowy to meet with Calculus leaves the airport, the number plate is 1941, but when they are welcomed after entering the base, the number plate is now 1491. (00:02:10 - 00:03:45)
Destination Moon: Part 1 - S3-E9
Continuity mistake: When Tintin discovers the shadow approaching the ventilation shaft, the shadow is first seen with his hand passing over the stain beneath the shaft. When Tintin gets a closer look, the hand of the shadow is yet to have his hand pass over the stain. (00:11:30)
Destination Moon: Part 1 - S3-E9
Continuity mistake: When Tintin tells the man outside the ventilation shaft to put his hands up, he puts his finger about half way down the man's back to imitate a gun. In the next shot, Tintin's finger is much lower down. (00:11:40)
Destination Moon: Part 1 - S3-E9
Revealing mistake: When the radar is telling the control station that they are standing by, in the background outside, there is a mark shown on the ground outside that appears to be flickering by appearing and disappearing between frames. (00:15:20)
Destination Moon: Part 1 - S3-E9
Continuity mistake: To launch the model rocket into outer space, Tintin pushes a lever with a green handle. Once the control tower is told to engage the nuclear motor, the first lever that Tintin had pushed is now a blue lever and the second lever that Tintin is now holding onto is a grey lever. Two shots after that, both the levers are now green. (00:16:00 - 00:16:35)
Destination Moon: Part 1 - S3-E9
Revealing mistake: When the countdown to engage the nuclear reactor on the model rocket has reached zero, Tintin pushes the second lever. It is apparent that Tintin is not actually holding onto a lever, but merely the animation is just drawn in a way to make it appear that he is. The green ball shown on top of the lever is not in the shape of a ball, but is really just the colour green that has been filled in through the gap between Tintin's thumb and finger. The lever doesn't even resemble a ball shape as it should. (00:16:40)
Destination Moon: Part 1 - S3-E9
Continuity mistake: When the two men are surveying the rocket movements, one of them is fiddling with one of the buttons. There is an arrow on the button, pointing towards an upwards position, but in the next shot, the arrow is pointing more towards the left. (00:17:55)
Destination Moon: Part 1 - S3-E9
Revealing mistake: Haddock asks Tintin if he can control the rocket's nuclear reactor and takes hold of the lever. It is apparent that he is not holding onto the lever. He is merely just miming the actions of grabbing onto the lever, when the lever is shown just below where he is holding. (00:18:40)
Destination Moon: Part 1 - S3-E9
Continuity mistake: When Tintin sees the detonator for the rocket, the two levers controlling the rocket are seen behind him. The levers are both level with each other, but once Tintin has rewired the detonator, the levers are in two different positions. (00:20:00)
Destination Moon: Part 2 - S3-E10
Deliberate mistake: The shot of the plane landing in Syldavia at the start of the episode, after the recap of part one, is merely the exact same shot of the plane landing in Syldavia at the start of the previous episode. Note the vehicles on the ground are completely identical and the plane, as well as its movements are also identical. (00:25:00)
Destination Moon: Part 2 - S3-E10
Continuity mistake: The plane that lands in Syldavia has a yellow stripe when it is first landing, but has a blue stripe when the passengers are exiting the plane. (00:25:05)
Destination Moon: Part 2 - S3-E10
Continuity mistake: When Wolff is explaining to Haddock that the space suit will be lighter in space, Tintin and Snowy are standing in front of Haddock, but when they are shown on the monitor in the next shot, Tintin and Snowy are standing more beside Haddock. (00:26:05)
Destination Moon: Part 2 - S3-E10
Continuity mistake: When Calculus is driving himself, Tintin and Haddock out of the base, Calculus drives down a hill and back onto the main road. Haddock is still sitting in his seat, but in the next shot, he is suddenly standing up. (00:30:15)
Destination Moon: Part 2 - S3-E10
Continuity mistake: When Tintin, Haddock and Calculus are going up in the elevator, the three are standing side by side, but in the next shot, Calculus is suddenly standing in front of Tintin and Haddock. (00:31:05)
Destination Moon: Part 2 - S3-E10
Revealing mistake: When Calculus is showing Tintin and Haddock around the rocket, they are in the deck below. Tintin and Calculus have already climbed down the ladder and Haddock is still climbing. Whilst Haddock is climbing down, the button on the back of his space suit vanishes for one frame. (00:31:50)
