I was just watching TTT yesterday when I noticed something a bit odd. Correct me if I am wrong, but Grima Wormtongue was a man of Rohan, right? Then why do you think PJ chose Brad Dourif who is not very tall, and gave him a black wig? The men of Rohan were said to be taller than mortal men and with golden hair. Grima dosen't quite fit this desription. I checked the book and couldn't find a description of him that said how tall he was or what color his hair was, so I am just going off the movies. So my question is: Why? Perhaps he is a move-in to Rohan, from Gondor or somewhere.
What are your thoughts?
