I don't want to say too much about LoTR, for the sake of spoiling it, but I will say one thing at this point--the yaoi fangirls are going to be all over this, because there is a whole lot of manbonding and hugging going on. The Fellowship is composed entirely of men, and aside from Gandalf and Gimli, they're young, attractive men (okay, Boromir isn't that good looking [in my opinion :3;] and Sam is kind of plump, but I still think Sam is cute in general, in both appearance and the way he's so devoted to Frodo). Let me predict some pairings:
Frodo/Sam (in fact, there's already stories about this..)
Aragorn/Legolas (nevermind the fact that Aragorn is clearly head-over-heels for Arwen..)
and possibly Merry/Pippin XP
Perhaps that was a bit prematurely cynical, but... I guess we'll see.

Also, slightly off topic, I just think it's interesting to note that Frodo and friends are in their fifties when they set out on this task (Well, Frodo is fifty, I assume Sam, Peregrin and Meriadoc are around that age as well), and they look in their early twenties, which makes me wonder how hobbits age... since Bilbo is 111, and after the ring is gone, he definitely looks it.
