The Lord of the Rings trilogy, directed by Peter Jackson, is one of the most intriguing and researched productions in cinema history. Fans of the films go to great lengths to learn about the making process and can turn the details they discover into viral sensations on social media. Due to the scenes being shot consecutively across the three films, many captivating stories have emerged, ranging from interesting moments on set to real injuries.

In The Fellowship of the Ring, Gandalf (Ian McKellen) accidentally hits his head on a chandelier while visiting Bilbo (Ian Holm) at Bag End for the first time. Peter Jackson confirmed in the DVD extras that this was an accidental occurrence and not part of McKellen's character. However, McKellen later claimed that this move was planned in advance and he thought it would add a fun touch to the scenes. Whether planned or accidental, that hit must have been quite painful.

The character Isildur, played by Harry Sinclair, has only one line in the trilogy: "No." This line appears in a flashback scene where Elrond (Hugo Weaving) tells him he must throw the One Ring into the fire. Peter Jackson, thinking Sinclair's voice was not suitable, had Weaving dub the scene later. Thus, in that scene, Weaving voiced both Elrond and Isildur.

The Council of Elrond scene in The Fellowship of the Ring is remembered for an interesting character who became an internet meme. An unnamed Elf, played by Bret McKenzie, sits next to Aragorn (Viggo Mortensen) and catches attention when Frodo (Elijah Wood) says he will take the One Ring to Mordor. This character, dubbed "Figwit" by fans due to his good looks, gained massive popularity on social media. Interestingly, his name is derived from the first letters of the phrase "Frodo is great... Who is THAT?"

Figwit's story became so viral that it caught Peter Jackson's attention, and McKenzie was brought back with actual dialogue in The Return of the King and The Hobbit: An Unexpected Journey. This viral campaign initiated by fans is one of the rare examples in cinema history of a character making a return to the screen in such a manner.

At the end of The Fellowship of the Ring, Aragorn is fighting the Uruk-hai Lurtz (Lawrence Makoare). When Lurtz finds Aragorn's dagger vulnerable, he throws it back at him. This throw was real, and Viggo Mortensen's defense with his sword and dagger was also genuinely executed. The prop used in the scene was thrown without prior negotiation, and thanks to Mortensen's reflexes, the scene was successfully completed.
