I am a beginner French learner, yet my native language has tu/vous distinction, loaned from French, so I thought I would have no problems with it. Alas. I was watching The Lord of the Rings: The Two Towers and noticed that pretty much everyone uses vous to talk to each other (I even drew the chart below).
I find this unexpected. I would expect Aragorn, Gandalf, Legolas, and Gimli (all close friends) all use tu among each other. I would definitely expect Gollum being addressed with tu - no-one has much respect for him. And I find it odd Gandalf addresses Saruman and Balrog with vous ("Vous ne passerez pas !") when they are in the middle of a fight.
As far as I can tell from searching on the Internet, French people don't speak that way outside the Middle-Earth (do they?). So where else would I expect to find people using vous so extensively? Is this some kind of archaism that is supposed to give me medieval courtesy vibes?
Edit: the arrow between two uruks had to be pink for tu.
