Okay, I have another legit question about Legolas, no drooling involved (Brad Pitt? ew). This will probably be a long post, sorry.
How old is he?
Orlando has said he (Legolas) is some 2900+ years old, and he must have gotten that from somewhere, but Tolkien never actually says. So I'm curious, all you expert types, what feeling do you get? Old or young (for an elf, of course)?
He constantly refers to the rest of the Fellowship as children (and how annoying must that have been for Gimli?), and when he says that the Rohirrim came out of the north 500 years ago, he seems to be implying that he was around for those 500 years and this is something he remembers. And he makes poetic observations like the fact that he has watched acorns grow up, grow old and die. The terrifically ancient Fangorn makes him feel like a child again, even though Mirkwood is an old forest itself and he doesn't seem to have any similar feelings towards it.
And yet, he doesn't seem to have traveled much, if he's old. He's never been to Lorien, he's never been to Fangorn (and doesn't know much about it). It seems that elves are travelling less as their era ends, and though he seems familiar with Elrond's home, Mirkwood and Rivendell aren't very far apart. But he does know the Lay of Nimrodel, so he's been somewhere to learn it or it's been brought to Mirkwood, so it isn't like no one travels.
And he acts fairly young sometimes. I can't picture Elrond or Thranduil or the other older elves we know doing the head-count with Gimli at Helm's Deep (one of my favorite scenes). He has a quick temper. Elves seem to be a bit tempermental anyway, but not many of the ones we meet are given to the flashes that Legolas shows (like when Gimli is stubborn about being blindfolded). He completely freaks out when they first see the Balrog. He's flexible enough in his opinions to make friends with a dwarf. He's fascinated with the Ents and eager to see Aglarond with Gimli.
I just can't get a fix on him! The best I can come up with is that he's youngish. Maybe a younger son, probably not the heir (since he seems to be Thranduil's messenger to Elrond, and he's a member of the Fellowship. So "a" prince of Mirkwood rather than "the" Prince of Mirkwood.) He's old enough to be an experienced fighter against Orcs and he has no fear of Men (I'm thinking of the first meeting with Eomer), but he's young enough not to be jaded, like Elrond seems sometimes and like his father (not a favorite of mine) seems most of the time.
What are some other opinions? You guys are the experts after all! :)
