Frodo (Elijah Wood), Saruman (Christopher Lee), Galadriel (Cate Blanchett), and Legolas (Orlando Bloom) are all returning characters from the Lord of the Rings films though none of them actually appear in the book The Hobbit. This is the same for Radagast (Sylvester McCoy), who is only mentioned in The Hobbit but does not actually appear until The Lord of the Rings. Conversely however, Radagast was omitted from The Lord of the Rings films.
