I honestly don't remember all the details about the first time I watched "The Fellowship of the Ring"... But I'll do my best!
I think it was the movie trailers in the cinema during the end of summer that made me want to see the movie. I was 13 at the time and just started a new school. When I mentioned my interest in the movie to my new friends it turned out that one of them loved the books - which I had never read. Well, I had tried to when I was 10 or 11, but I thought they were boring. ._. I decided to give them another try - and I was hooked. Me and my friend had so much fun that term, always discussing the books (including "The Silmarillion" and "Unfinished Tales", etc.) and talking about the movie. We were so excited about it and in the end all I could talk about was the books and the movie and my predictions about the movie!
I didn't go to the premiere. I don't remember how long I waited, though. I guess I could look it up, as I believe I wrote about it in my diary...

I went together with some friends - but sadly I don't remember clearly who they were... But my LotR-friend, I think she watched the movie before me with some other friends of hers.
Anyway, we had seats in the top row, to the far left, right above the stairs. I do remember that! I remember walking out of there and wanting to go back inside and start the movie again... It was so amazing! So much adventure and action and friendship and beautiful views and and and... I was totally amazed that there even were such scenery in the world. There were some changes that I didn't like so much and some that I didn't like at all - and I still rant about it sometimes - but as a whole I loved the movie!
Back then, Elijah Wood was my favorite. I remember watching a lot of documentaries and behind-the-scenes before and after the movie premiere, and I was just really fangirl-ish about him... By the end of the trilogy, that had changed and my new favorite was Viggo Mortensen - I just love that voice and those eyes!
I must say that my main LotR-fan period was between age 13 to 16-ish. I still had my friend to discuss the books and movies with, and most importantly - I still had time to be fanatic about it. That changed during upper high school, sadly. But there are a few events and happenings that I remember from my crazy fan period. I would watch the movies over and over again, marathon-style, only leaving the television to eat and sleep (because my Mum told me to...). Anyway, there was this event in 2004 or 2005, I think. A group of Swedish Tolkien fans gathered at a university for a weekend, and we watched all the extended editions back-to-back. We had one break, to order pizza... Apart from that, we sat in the university's cinema room, and it was wonderful to watch the extended editions on a big screen!
Lately I haven't watched the movies much. I even think it's been two years since last time.

But they are still my favorite movies and I pretty much know them by heart as I watched them so often when I was younger! Hm, I should try to watch them again soon... Some kind of warm-up for "The Hobbit"...
I had been thinking of closing this topic after some time, but I've decided to keep it open, giving more of you the chance to reply (and earn some Silmarils)!
