The Extended Edition has the listing of the Lord Of The Rings Fan Club members, similar to Extended Edition of The Fellowship Of the Rings.
Special thanks to ... and to the thousands of others who helped make this film a reality.
One section of credits is for the "Hammerhands" (presumably for carpenters). This is a reference to the name of the "historical" founder of Helm's Deep, Helm Hammerhand. Also, apprentice builders are known as "hammerhands" in New Zealand.
On the extended edition, John Noble, who plays Denethor, has his name typoed as John Nogle.
Just like the previous "Lord of the Rings" movie, there are no opening credits after the title has been shown.
