Factual error: When Sid gives his credit card to Jay to pay for their meal because Jay's mom doesn't have enough money, a magnetic strip is on the back of the card. This technology wasn't used on credit cards until 1980. The film takes place in the 70's.
Factual error: Loosely based on the novel by Jules Verne, the entire story takes place on a remote Pacific island in the early 1860s. However, as pirates come under attack by a sea monster (in the second half of this two-part film), a modern fishing trawler or tugboat appears momentarily on the far right of the screen. (00:59:05)
