In March 2002 a 3-minute preview of the sequel, The Two Towers, was added to the theatrical release right before the end credits, making the film's running time 181m. This was later an easter egg on the extended DVD.
In the US theatrical and DVD releases (both versions), the New Line Cinema logo at the beginning says "An AOL Time Warner Company" underneath it. For the US Blu Ray release (both versions), the logo has been changed to simply say "A TimeWarner Company" underneath it.
The Extended Edition DVD includes the following changes to the film.
- During the prologue, more is shown of the ambush and death of Isildur, emphasizing his betrayal by the Ring.
- After the prologue, we open with a close-up of the Middle Earth map and pan to hear Bilbo writing his book, starting with a description of hobbits. Much of the Gandalf-Frodo dialog in their first scene together is removed, including the subtitle "60 Years Later".
- When Gandalf and Bilbo are in Bag End, Bilbo notes that the people knocking on his door are the Sackville-Bagginses.
- During the party, Bilbo greets a guest, then hides from the S.B's with Frodo. He tells Frodo how much the latter means to him.
- After the Ringwraiths set out, the Hobbits (prominently Merry and Pippin) are shown dancing and singing in the Green Dragon Inn. References are made to troubles in the outside world and Frodo encourages Sam to pursue a relationship with Rosie Cotton.
- After Frodo and Sam set out, they hear singing and find the woodelves leaving for the Gray Havens.
- After the company leaves Bree, they pass through the Midgewater Marshes. Later, Aragorn brings a killed deer to the hobbits. Frodo wakes up late at night to hear Aragorn singing about Beren and Luthien.
- The stone trolls from "The Hobbit" are shown.
- Additional dialog between Aragon and Boromir during the "still sharp" scene with Narsil.
- In the Council of Elrond, Boromir mentions his dream and reaches for the Ring. Gandalf recites the poem "One Ring to rule them all.." in black speech, causing the ground to shake and sun to go dark and provoking Elrond.
- After the Council of Elrond, Aragorn visits his mother's grave and remembers Elrond telling him of his destiny. This is followed by another scene in which the company are sent off by Elrond and the elves.
- Gandalf stops Frodo as they approach Moria to warn him about the Ring's power growing.
- In the mines, Gandalf mentions mithril and lights up an old mithril mine. He notes the value of Bilbo's mithril shirt.
- Additional fight scenes during the battle in the Chamber of the Marzabul.
- Lothlorien is completely revised. The company are first on Haldir's left with the Elves distrusting Gimli and leery of Frodo.
- Scene of the elves and the company approaching Caras Galadhon.
- More dialog when Celeborn and Galadriel meet the company.
- Sam recites a poem verse about Gandalf.
- Galadriel acknowledges her possession of one of the elf-rings.
- As the Fellowship leaves, Galadriel gives them each a personalized gift that will end up being critical to their future. Legolas gets a special bow, Sam gets some elven rope that comes in handy when he & Frodo make their way through the Emyn Muil, Frodo receives the Phial of Galadriel, and a touching moment occurs between Gimli and Galadriel.
- Celeborn gives Aragorn a knife before they leave and warns them they are being tracked by something.
- Boromir spots Gollum following the boats. Sam tries to get Frodo to eat or sleep. An exchange between Aragorn and Boromir about going to Minas Tirith before setting off for Mordor.
- Extra action in the final battle.
- An important extra line of dialog in Boromir's final scene.
- 10-15 minutes of fan club credits during the final credits.
One photograph from unused publicity shots shows the four hobbits making there way through a swamp, presumably the Migewater Marshes from the novel. This sequence does not appear in the final cut of the movie but is included in the Extended Edition DVD
In the Extended Edition, the opening title, "The Fellowship Of the Ring", appears while Bilbo is writing "There and Back Again: A Hobbit's Tale", contrary to appearing while Frodo is reading in the theatrical release.
In the extended DVD, the discussion Gandalf and Frodo have in Moria about Gollum has several more lines. In particular, Gandalf tells Frodo Gollum's original name, Sméagol, and that Gollum was once a Stoor Hobbit. Frodo's knowledge of this becomes important in the next film, The Two Towers.
The extended version was originally planned to be rated R, but due to most of the new scenes focusing on more character development than extra violence. The PG-13 rating remained intact, if not slightly more intense.
In the extended version there is actually a line missing. In the very beginning of the movie Gandalf mentions Hobbits as being ignored, thing of which he is most thankful; this line is not in the extended DVD version.
In the theatrical release and the Extended DVD, when Aragorn is fighting the Uruk-hai that killed Boromir (Lurz), Aragorn stabs him in the leg with a knife, the uruk-hai then pulls the knife out of his leg and greedily licks the blood off of it before throwing it at Aragorn. This scene is cut out of the Theatrical Edition DVD.
In the extended edition, the nature of Bilbo's party plan is very different. In the original, the film made it seem like Gandalf was in on the joke and was keeping mum about it with Frodo, keeping the happy air of the Shire scenes. However, in the Extended Edition, further close ups and different dialogue takes show that Gandalf not only is unaware of the trick but actually is concerned about it.
In most TV versions of the film the "Infamous Car" can still be seen (see goofs)
