The Lord of the Rings: The Return of the King "The Lord of the Rings" trilogy was the most nominated film franchise in Academy Award history with 30 nominations, but the "Star Wars" film franchise overtook it with 37 nominations when the sequel trilogy was released (starting in 2015).
Viggo Mortensen estimates that during filming on the trilogy, and including all takes, he "killed" every stuntman on the production at least fifty times.
In February 2004, it became the second movie to break the $1 billion mark in worldwide box office revenue. "Titanic" (1997) was the first.
The dead oliphaunt carcass used in this movie is reportedly the largest film prop ever built. According to those in the prop department, director Peter Jackson still thought it could've been bigger.
