Goofs

Returning to the boat, Tintin and Hoddock pass their remaining vase to a deckhand before going below. They look in one room, but as they enter the captain's cabin, Haddock has the vase again.

Tintin leaps to the window to espy Midas' gunman, gripping the vertical window slats. The shot changes and now he's grasping the horizontal bars.

During Tintin's dive, the rope that connects him to the boat is sometimes visible, sometimes not.

Near the end as the marching band comes towards Haddock and Tintin, Professor Tournesol can be seen at the far right of the screen awaiting his cue carrying his latest invention.

During the car chase, the man in the white suit fires his gun at Tintin and Haddock, but there is no flash of light nor any smoke visible.

In the final scene, wires are visible holding up Tournesol's parrot-copter invention.
