Now that I think about it, the movies really have impacted my view on a few of the characters:
*Treebeard- I never could really imagine how he looked, or make sense of the description, although the movie's version of him is obviously not exactly to the book, I have a lot more to go on when I try to visualize him.
*Frodo- I imagined him as the typical hobbit, a bit less hefty because of his frequent walks that he liked to take, but still more or less the typical hobbit. I've got to admit that I like his movie look a lot better, PJ really did a good thing when he aged Frodo down to about 20 something (in the movies of course).
*Orcs- I always imagined them as these dark, hairy creatures, but you couldn't really see anything except their red eyes, very steriotypical of me

. When I first saw them in Fellowship of the Ring I thought two things:
Oh yeah, this is definitly how Orcs should look...

This is going to be an awesome movie!
