[Lindale]

That part was all right; otherwise, it would all be too-stereotypical Hero that does not know or show fear. It showed (a bit?) of Gandalf's human-ness, because even in the books Olorin said he was afraid. (See the UT, The Istari, I don't have that book right now in my pocket). In my opinion Jackson did a pretty good job at the movies, and though the book version is almost always better than the movie, he interpreted the book really good.
