During Boromir’s death scene in the Fellowship of the Ring film, you a hear a choir in the soundtrack. The choir isn’t singing random vowel sounds; they’re actually singing in Elvish.
The English translation of the lyrics? It’s a line from the books: “I do not love the sword for its sharpness, nor the arrow for its swiftness, nor the warrior for his glory. I love only what they defend.”
For bonus hurt points– in the book, those lines were said by his little brother Faramir.
