Other mistake: When they are in San Francisco, notice the pianist. The keys he presses don't correspond with the notes he's supposedly playing. It's a little bit obvious that the music was recorded in advance.

Sir Francis Gromarty: One thousand pounds for an elephant? It's outrageous! You've been diddled.
Phileas Fogg: Undoubtedly. But it's not often one needs an elephant in a hurry.
Trivia: There was no balloon in Jules Verne's book. Thank to this film, most people now can't imagine "Around the World in 80 Days" without the balloon. (Gas balloon, not a hot air balloon as most people think).
