Had to fetch prop gun from ocean floor which dropped during pirate melee
That's one of my fav film trivia bits. No one is allowed to litter/lose physical items in the ocean. One of the guns they used during the pirate sequence landed in the water & sunk, they had to dive down to retrieve it lest they get fined or worse.
Not only do I like that they went to that extent, I also love that law exists & gets respected.
