Confused about Quotations!!

[Firefoot]

I don't really mind that he changed the quotes around. What does bother me is when I am trying to remember a specific quote and I cannot remember exactly how it goes because the movie switched it up. That does bother me. The most specific one that I can think of right now is actually a very small one, but one of my favorite book quotes nonetheless: the movie says something like "I am glad that you are with me, Sam, here at the end of all things" whereas the book is "I am glad that you are here with me. Here at the end of all things, Sam." The part about Éomer talking about chopping off Gimli's head is another that bugs me a bit.

As to why, sometimes I think that the book uses 'higher' language (which I like very much) and like Estel said switching it around would make it flow better, and sound more 'common' so that people could better understand.
