In Elrond's vision of a dead Aragorn, it is Anduril he has clasped to his chest, not his ranger sword. This is a bit of a spoiler, as Elrond himself reforges and gives the sword to Aragorn in the third movie. In the books, he reforged the sword right before or after the council at Rivendell.

During the filming, Viggo Mortensen (Aragorn) and Orlando Bloom (Legolas) would rib each other quite a lot. Mortensen would tell Bloom to go brush his long, blond hair and get another manicure, because the Elves are so prissy. Bloom would call Mortensen a dirty human (which is entirely true as he rarely bathed during filming) and say that at least the Elves live forever (which is entirely false and is based on a popular misconception of how long they live).

When Elrond gives Arwen his hard-father talk before sending her away, he asks, "Do I not also have your love?" and she replies, according to the subtitle, "You have my love, father." Actually she said, "Gerich veleth nín, Ada." Adar = "father", but Ada = "papa". One of many nuances lost in translation in the films' subtitles.

During the location shooting at Edoras, there were very strong winds, as can be seen by the actors' hair, especially Éowyn's. During one particular day's filming, the wind was so strong that it tore Peter Jackson's glasses right off his face, and was blown straight down the hill. He had to spend the rest of that day without them. Submitted by Rikki
