Factual error: When we first see Bambi as an adult, it is meant to be the same year (no revolving of the seasons or such to denote time passing). Yet the adult Bambi seems to be three years old as his antlers have two 'tines' or forks on them. In a male deer's first winter he grows two straight horn-like antlers on his head, which is the first 'tine'. After this the number of tines on the deer's antlers increase one with each year. So, counting the year when Bambi was a fawn and had no antlers, he has the body of a 3-year-old deer. Yet judging by the story's progression and the relative ages of Thumper and Flower (remember, smaller animals mature faster) Bambi is only 2 years old.
Factual error: When Wilbur and the others are going to save that black sheep from the fox, you see some pawprints on the ground, supposedly from the fox. Fox prints are smaller, and should have claw marks.
Factual error: When Bud-dha is meditating one morning, to his left is the way they came from, and to his right is the way they had been headed the day before (which they say is true north). But, He's facing the sunrise. The sun rises in the East, not the West, so the sunrise should be behind him. Then, after that, when the puppies set off again, they head towards the sunrise, though they're supposed to be headed "true north".
Factual error: When Chuck discovers the dry rot, he tells the Persons that he played 36 seconds for the Lakers in the 1986 NBA Finals. The Lakers weren't in the 1986 Finals.
Factual error: Selena, the Goddess of the Moon, sets the next "earthset" as Zenon's deadline. One shot shows the Earth slowly sinking towards the lunar horizon while Zenon and Dasha watch. However, the moon takes exactly as long to rotate on its own axis as it does to orbit the Earth. As a result, the Earth does not rise and set as seen from any one location on the moon. It only rises and sets as you move across the surface of the moon.
Factual error: When Ralph is shooting the final two free throws of the championship game, his feet cross the free throw line before the ball hits the rim. This is a lane violation in the National Federation of High Schools which governs middle and high school sports. The correct call would have nullified both shots and the points they scored.
Factual error: When Cindy is giving her "fossil-to-chromosome ratio" report, she calls her model dinosaur skeleton a plesiosaur. However, the skeleton is of a bipedal dinosaur (likely a hadrosaur, judging by the "duckbill"), while plesiosaurs were aquatic reptiles with flippers instead of feet.
Factual error: There are mountains in the background in several of the scenes, but there aren't actually any mountains in or near St Louis.
Factual error: American style fire hydrants are seen at least twice, but they aren't used in the UK.
Factual error: Zuko pulls out a family portrait out of his shirt and the portrait looks nothing like the characters in the movie, they look more like the cartoon characters.
Factual error: When the alien craft speeds away from the NASA base, its slipstream tears off the roof of a small booth. But the wake also should sweep the people in its flight path down to the ground; it is too close for that not to happen.
Factual error: When the family is driving from New York to New Jersey, you see a highway sign for the exit for New Jersey. In the background is a Dofasco building which is in Hamilton, Ontario, very far from New York or New Jersey.
