Trivia: According to the Guinness Book of Records, the Lord of the Rings holds the record for the greatest number of false feet used in one movie: 60,000.
Trivia: After Stuart Townsend was deemed too young for the role, Viggo Mortensen was convinced by his son, Henry, to take over the role of Aragorn.
Trivia: When the Hobbits enter Bree, right after the wheel of the carriage passes in front of them, there is a man you see to the right who's holding a carrot and burps. That is Peter Jackson making a cameo appearance.
Trivia: While filming the trilogy, Viggo Mortensen got so into character that, during a conversation with Peter Jackson, Jackson addressed him as "Aragorn" for more than half an hour, and Mortensen didn't even realize it.
Trivia: Viggo Mortensen wasn't originally cast as Aragorn. Two weeks before shooting, Peter Jackson realized that his first choice for the role (Stuart Townsend) was too young and decided to offer the role to Mortensen.
Trivia: When Merry and Pippin have just taken the dragon firework from Gandalf's cart and are in the tent tossing it back and forth, Pippin shrieks when it goes off. Apparently, Peter Jackson had told Billy Boyd it would only spark and fizzle, so he was fairly surprised when it shot off in his hands. He talks about this in the commentary on the DVD.
Trivia: Lawrence Makoare, the actor who plays the Uruk-hai leader Lurtz, later plays The Witch King of Angmar in The Return of the King. He also plays Gothmog, the orc commander in ROTK, plus several other Uruk-hai and orcs throughout the trilogy.
Trivia: When filming "Fellowship," the actors playing the Hobbits required hours of work just to get on their Hobbit feet. It was so long and terrible that Sean Astin (Sam) counted the amount of times they had to put their feet on when it never showed up on camera in that day of filming. The final count was 50.
Trivia: When running away from the Balrog, Boromir is the first to reach the bottomless stairs and Legolas pulls him back to safety. When this piece was shot, there were many retakes, and each time Sean Bean would get pulled back by Orlando Bloom, Bean would land back onto Bloom's soft lap, while Bloom would slam back onto the hard steps with the full weight of the two of them. As a result, Bloom had bruising on his backside and legs, for some time. Bloom joked, "I gave Sean a few beatings for that, I can tell ya." Cast commentary, extended DVD.
Trivia: When the four Hobbits are in the woods running from the Ringwraiths, they run onto the boat at Buckleberry ferry and go to Bree. Merry, Pippin and Sam get on alright but Frodo has to jump. The first time the filmmakers shot this scene, Elijah Wood jumped right over the ferry and into the water on the other side.
Trivia: In all the close-up shots of Galadriel, you can see a reflection of a ball of white Christmas lights that was held up near the camera. The filmmakers did this to make her eyes look deeper and more complex.
Trivia: The Orc blacksmiths beneath Isengard are the WETA workshop staff who made the weapons for the film.
Trivia: The actors who played the members of the Fellowship all got the Elvish symbol for "9" tattooed somewhere on their bodies, apart from John Rhys-Davies (who plays Gimli) who sent his stunt double instead.
Trivia: During the scene before Bilbo's party, when Gandalf and Bilbo are inside Bag End, Gandalf hits his head on a beam upon entering Bilbo's study. This was actually unintentional, but Ian McKellen did such a good job of acting through it that Peter Jackson left it in the movie.
Trivia: Alan Lee (a Tolkien artist and conceptual designer with John Howe) has a cameo as one of the nine men who received a Ring of power in the Prologue.
Trivia: According to the book, Frodo is the oldest of the Hobbits in the Fellowship, but Elijah Wood, who plays Frodo, is actually the youngest of all the Fellowship actors - he was seventeen when filming began. The actors who played the younger Hobbits (Merry, Samwise and Pippin) - Dominic Monaghan, Sean Astin and Billy Boyd - ranged in age from 23 to 31 at the beginning of filming. Ironically, in the book Pippin is the youngest of the four Hobbits, whereas Billy Boyd, who played Pippin was actually the oldest of the four actors portraying the Hobbits.
Trivia: Sean Bean (Boromir) was deathly afraid of riding in the helicopter that had to take the actors to and from the many filming locations. After the scene on Caradharas, the one where Boromir tries to take the ring from Frodo, Bean refused to go anywhere else by helicopter. Many times he had to take a ski lift and climb many hundred feet in full Boromir gear to get to the set.
Trivia: When Frodo falls over in the snow and loses the Ring, there's a close-up of the Ring, with Frodo in the background. A giant ring of six inches in diameter had to be used to keep both Frodo and the Ring in focus.
Trivia: Christopher Lee (Saruman) read "The Lord of the Rings" once a year, and was the only cast member to have actually met J.R.R. Tolkien.
