Yet to read Simillarion at all, mainly as i was under the impression that its a grand sweeping...but unfinished story.
Like Grom - read the hobbit whilst i was at school at around the age of 9 or so. It was our class book, and although our English teacher was a complete cow - she was a Tolkien fan luckily. I then read the Fellowship and Two towers as well, and i was hooked (bear in mind that i only read fantasy stuff like Tolkien, Eddings etc at this age). The Library didn't have ROTK for a good year or two due to a pupil nicking it, and i think i finally read it by around the age of 12. The whole story stayed vivid (strangely enough mainly the Fellowship!) until I read the books again a few months before the film came out.
Love the books, love the films, love the extras on the DVD that show just HOW hard they tried to get everything perfect.. The only thing that didn't seem to match my immagination was that i imagined orcs as per the normal short, fat green guy with pointy ears and teeth sticking from his lower gum out through his mouth, wearing some armor, and carrying a round sheid
The films really impressed me
