Yessss! Brad Dourif as Grima Wormtongue! Cast a freak to play a freak! He is uber cool. He was Piter De Vries in David Lynch's Dune, played a great troubled character in one Episode role in Babylon 5 (which was really like LOTR in space), Saavedro in the video game Myst III: Exile, the voice of Chucky in the Child's Play movies, and lots of psychos in lots of other films and TV. He really is a fantastic character actor.
Glor... fin... el? Darn... Well, I can accept my flaw with spell check, now... But whacking orcs still makes me feel good! BAM! BAM! BAMBAMBAM!!! Yeah... Take that, Orc-face.
