Tarzan (1999)

Factual error: When the humans are capturing the gorillas, Clayton fires about 15 rounds from his double rifle. This is pretty impressive, considering this is the early 1900's.

Jane Porter: I was saved! I was saved by a flying wild man in a loincloth.

Trivia: You can look in the clouds when Jane decides to stay with Tarzan and see an angry gorilla and Jane's father. They are in the clouds to the left.

Question: Throughout the movie we rarely see Clayton reload his gun. It looks like a twin barrel shotgun. During the final fight between Tarzan and Clayton how could he have fired more than 2 rounds without reloading it?
