Continuity: When the car which becomes Chitty crashes in the beginning, the vent and the front left wheel become totally loose, but in the next scene where the children are playing in it, the vent and the wheel are attached.

Audio problem: In the scene where Chitty Chitty Bang Bang is passing the train you can see a continuous trail of smoke issuing from the train. It is exiting from the train's whistle, meaning that there should be a continuous high pitched whistling noise, yet there is no such thing.

Revealing: In the king's birthday party scene Mr. Potts is dressed in a rag doll costume. In some shots you can see the wire that holds him up when he jumps.

Factual error: After they pick up Truly Scrumptious in the newly refurbished Chitty Chitty Bang Bang, look at the road surface as they run alongside the GWR train. There is a broken white line running down the centre of the road. These types of markings weren't introduced in England until the blackouts of WW2.

Other: When the Bulgarian soldiers storm the village to find the children, one soldier pushes open a door and the soldier next to him butts the already-open door with the end of his gun, making him fall forward slightly.

Revealing: In the "Truly Scrumptious" song, the children draw a smiley face in the sand. When they run across to make the smiley face, you can see that it has been created beforehand.

Visible crew/equipment: When Caractacus is being dragged across the ground by the rockets, the wire he is holding onto is visible.

Continuity: When Truly accompanies Mr. Potts and the children to the beach, her hair is first in a bun, and then later is worn down around her shoulders when they reach the beach. Also, the tightness or her curls vary from scene to scene while at the beach.

Continuity: When they are almost done singing "You Two" there is a big ripple in the tablecloth. After they finish singing and the plates are rolling down, the ripple is gone.

Continuity: In the scene where Mr Potts is putting the children to bed they offer him the objects from their treasure chest: a ivory tusk, "jewels" and a "crown". Near the end of the song he puts the objects back into the box but not the crown.

Continuity: When the child-catcher captures the children in the cage, the circus decorations fall off as the wagon quickly pulls away. Two shots later, the wagon is shown passing the fallen circus decorations on the street.

Revealing: When Truly Scrumptious is driving the children to their home, the car is on a rig or platform. The wheels are not rotating.
