Factual error: When Kharis is being examined by Petrie, he says that the lines on his face were caused by him being buried alive. In the next sentence he goes on to say that Kharis shows the best example of the embalmer's art that he has ever seen. Strange - if you're planning on burying someone alive you wouldn't embalm them first - that process would kill them!
Factual error: The pirates should have been crushed by the pile of rolling logs, but they just keep coming. No dead bodies, no blood, no guts, but hey, it's Disney.
Factual error: The copper pot Jiminy looks into shows his reflection at a larger size. It should be reflected at a smaller size though.
Factual error: The famous battle between Stegosaurus and Tyrannosaurus Rex (which is incorrectly depicted as having three claws) never took place: Stegosaurus was extinct before Tyrannosaurus evolved. (Stegosaurus lived in the Jurassic, Tyrannosaurus in the Cretaceous.)
Factual error: The movie "Santa Fe Trail" (1940) starring Errol Flynn, Ronald Reagan and Raymond Massey, is the story of John Brown's raid on Harper's Ferry in 1859. The president is shown to be Abraham Lincoln, who wasn't inaugurated until February of 1861.
Factual error: Crawley tells the girl that Rebecca's body was in the sea for two months and Maxim had to identify her, which is totally ridiculous: A body in the sea for two months would have been eaten and nibbled on by everything that eats meat and is passing by; there would be hardly anything left.
