It’s hard to believe it’s been nineteen years since Peter Jackson’s fantasy epic The Lord Of The Rings trilogy hit theatres. The films ruled pop culture, the awards circuit, and the box office during their release in December of 2001, 2002, and 2003. For years, studios and directors alike deemed the books by J.R.R Tolkien “unfilmable.”

Even director Peter Jackson didn’t imagine he’d step up to the task twenty years after finding the world of Middle Earth. The trilogy shot back-to-back in his native New Zealand, which developed an entire industry out of the success of The Lord Of The RingsSome of the then-unknown actors skyrocketed to super-star status and had numerous opportunities coming their way.

The Lord of the Rings: The Fellowship Of The Ring is a labor of love. Much of the technology didn’t exist before filming. Weta Workshops made all the prosthetics, weapons, miniatures, and about everything else. The series revolutionized the film industry. Read on for 15 things you didn’t know about the making of The Fellowship of the Ring.

Bilbo’s (Ian Holm) returns to Bag End and packs his things to leave the Shire. Bilbo gets a little Gollum-y when Gandalf (Ian McKellen) reminds him to leave the Ring. He reluctantly turns his palm and drops the Ring. Sound engineers added the thud in post-production, but the magnet pulls the Ring, symbolizing its weight and power.

Audiences spot Gollum three times during the trilogy’s first installment: in the prologue, voiced by Galadrielle (Cate Blanchett), his torture by the Ringwraiths in Mordor, and his eyes, in the Mines of Moria. WETA hadn’t completed the character’s design, so he changes between the first and second films.

Gandalf’s firework display is a highlight of Bilbo’s one-hundred-and-eleventeenth birthday. Merry and Pippin, nosy as always, find their way onto Gandalf’s wagon and unwittingly set a dragon upon Hobbiton. Billy Boyd, who plays Pippin, didn’t expect the prop to make noise, so the shriek audiences hear was his genuine reaction, and it made the final cut.

When trapped on top of the Tower of Orthanc, Gandalf uses his magic to call upon an ally. A moth flies into the shot and lands on Ian McKellen’s hand. The moth was born right before filming started that day and died right after director Peter Jackson got his shot.

One of the most significant challenges while shooting The Lord of the Rings trilogy was balancing the different actors’ heights, depending on the species of Middle Earth they play.

Actor Christopher Lee was the only member of the cast to have met J.R.R Tolkien in real-life. Ian McKellen took inspiration for the voice and accent of Gandalf after listening to recordings of the famed Oxford professor lecturing. It makes sense to model the wisest character on the world’s creator.

In the prologue, audiences see Bilbo stumble upon the Ring in the Misty Mountains. With Andy Serkis not yet cast in the role of Gollum/Smeagol, Dominic Monaghan, who portrayed Merry, stepped up and took on the part. Gollum shrieking after losing the Ring in the final film is Monahan.

While it wasn’t comfortable for the Hobbit actors to undergo the near two-hour process of having their prosthetic feet and ears put on, Orlando Bloom was allergic to the blue contacts he wore to portray Legolas, which explains the inconsistent eye color. John Rhys-Davies broke out in hives, and his face reacted to the full face prosthetic.

None of the Hobbits wandered beyond the Shire before the events of The Fellowship. Pippin bemoans Aragorn for his ignorance toward Hobbits’ feeding schedule.

The full-body prosthetics required to play chief Uruk-hai Lurtz made it hard for the actor to move and aim. The script called for Lurtz to launch the dagger at the tree. Viggo Mortensen reacted quickly and blocked the blade with his sword. The epic move made it into the final cut.
