Peter Jackson's and Fran Walsh's children are listed in the credits as 'Cute Gondor children'. In the Fellowship of the Ring, they were 'Cute Hobbit children' and in The Two Towers, they were 'Cute Rohan children'.
At the end of the credits, a very long list of names from the Lord of the Rings Fan Club whom the authors want to thank to is displayed. The name of Elijah Wood is in that list.
There's a text written in maori: Me mahara tonu taatou nga Uri- aapakura noo tuaanuku nei, noo te waaotuu te tu kekehua ana o ngaa Eldarin kua hohouu mai i te Uru-moana. Which is in english: Let us dedicate our memories to the spirits of the Eldar who came to us from the Ocean that lies to the West.
The credits are accompanied by preproduction sketches that appear along the left and right sides of the screen. The final sketch, in the center of the screen, is The One Ring.
Christopher Lee, who played Saruman in the film was not originally credited at the end of the film as all the other main characters were because he did not appear in the theatrical version. For the Extended DVD however, he does appear in the film and justly gets his drawn character and name credit with the other actors.
In the theatrical version Sean Bean receives a major on- screen credit at the end of the film, even though he only appears on screen momentarily in a flashback from the first film.
Concept sketches behind the credits show images of locations in the sequence they were seen in the film, ending on the rounded doors of the Shire.
Just like the two previous "Lord of the Rings" movies, there are no opening credits after the title has been shown.
