Best adventure movie mistakes of 1972

Visible crew/equipment: When Rev. Scott swims up the first stairwell, after pushing aside the dead crew member, as his head comes up the shaft, you can see, very quickly, the flippers of a crewmember swimming out of the shot behind him. (01:22:55)

Revealing mistake: When the mountain man is grinning at Jon Voight tied to the tree, you can see that his "missing" front tooth is actually painted black.

Revealing mistake: After Alice falls down the hole, into the leaves, she gets up and runs down a stone to follow the White Rabbit. As she runs down the stone, it quite visibly squashes down under he feet, revealing that it is foam.

Continuity mistake: When Tintin and the two kids are escaping from the submarine lair, the water level keeps changing. It's supposed to be more and more high, but it's lower in some shots.

Revealing mistake: Freeman Lowell has several cargo containers dumped off the spaceship, to make it appear the ship has suffered an accident. A wide shot shows the ship receding in the distance, with the containers rolling weightlessly in the foreground. As the foreground containers pass slightly in front of the more distant ones, they don't mask them; their images overlap. The containers were apparently composited into the shot with simple multiple exposures. (00:35:40)

Visible crew/equipment: When Spencer and Hill fly the second air plane, the studio headlights are mirrored in Hill's sunglasses. (00:20:35)
