*Tolkien's stuff, really great masterpieces.
*Pratchett, to a certain limit. Too much Pratchett makes everyone crazy.
*Anne McCaffrey's "Dragonriders of Pern" series.
*Robert Jordan's books. Especially "The Eye of the World".
*C.S. Lewis, "The Lion, the Witch and the Wardrobe"

Looking forward to the movie...
Also, I just finished reading Christopher Paolini's "Eragon". Not bad at all. When the second part of the Heritage trilogy comes out, I might add it to my favourites...
