On the carpet of the floor of Peter JacksonPeter Jackson's house, they filmed the facial reaction of Smeagol/Gollum when he realizes Frodo intends to destroy the ring.

- John Rhys-DaviesJohn Rhys-Davies provides the voice of Treebeard (uncredited for this movie, but credited for The Lord of the Rings: The Two Towers).
- Filming was progressing on The Lord of the Rings: The Fellowship of the Ring in the location of Queenstown when suddenly the town was hit with massive floods and exterior filming had to be suspended. The only available indoor facility that could be used for a studio set was the squash court in a local hotel. Thus, the next day the next scene to be filmed was the intense moment from The Lord of the Rings: The Return of the King when an obsessed Frodo sides with Gollum and sends Sam on his way. Both Elijah WoodElijah Wood and Sean AstinSean Astin balked at having to do such a pivotal scene without preparation (Andy SerkisAndy Serkis had not been cast at this point so someone from the crew filled in for Gollum) but filming went ahead as planned. Astin's scenes were all successfully completed. The next day, however, the sun came out and the floods abated so exterior filming could resume. The intent was always to return to the squash court (where the set remained standing) to do Elijah WoodElijah Wood's scenes, but, for the next five weeks there was no rain to interrupt exterior filming. At the end of that period, the crew had moved to a new location. Elijah WoodElijah Wood finally got to do his side of the scene one year later in the same location - the squash players of Queenstown had been without a court for that whole amount of time as the set had remained in place on the court the entire period.
- Billy BoydBilly Boyd (Pippin) sang and composed the tune for the song in Denethor's hall (Tolkien wrote the lyric).
- The last shot of principal photography was when the newly-crowned Aragorn bows to the four Hobbits. Although Viggo MortensenViggo Mortensen did not need to be on set for that day, he nevertheless insisted on attending. He didn't have a crown (it wasn't necessary - he wasn't being filmed) so he fashioned one out of paper. With each successive take, the crown was becoming more ornate and sillier as crew members kept decorating it, so the four actors playing the Hobbits often had difficulty suppressing their giggles.
- In the scene when Denethor burns Faramir on the pyre, the pyre could not truly be on fire because Gandalf's horse would not go near it. To solve this, the crew reflected a real fire onto a pane of glass in front of the camera so that it looks as though the pyre is burning.
