Sean Bean is so afraid of flying that while filming The Fellowship of the Ring, he chose to hike across the countryside rather than take a helicopter.
Before filming LOTR: The Fellowship of the Ring, Jackson made the principal actors train for 6 weeks in sword fighting, riding and boating to allow the cast to bond. Later, most of the actors portraying the Fellowship got a tattoo with the Elvish symbol for the number 9.
Christopher Lee received Tolkien’s blessing to play the role of Gandalf, if a movie was ever released, but he played Saruman instead. He was also the only person involved with the Lord of the Rings films to have actually met Tolkien himself.
Sean Connery was offered the part of Gandalf in the Lord of the Rings trilogy, and 15% of the box office takings of the movies, but turned it down because he didn’t understand the script. The 15% ended up being nearly 450 million dollars.
Tolkien didn’t write the Elvish languages to fit into the Lord of the Rings, but wrote the Lord of the Rings as a history for his over 15 different languages.
Filming of the Lord of the Rings trilogy pumped roughly $200,000,000 into the New Zealand economy.
