Orlando Bloom is not on my list of Really Great Actors, but I can think of worse ones.
I think since he's new in the business, the only kind of jobs he can get are pretty-boy-look-at-me roles, and I think Peter wanted him to sum up Aragorn's eloquent speech for all the girls who were concentrating on just him.
Please don't kill me.
Anyway. I thought he was good in Black Hawk Down, even though he had a tiny role and it was all his character's fault.
I have a question. Why didn't they dye his eyebrows blond? It honestly isn't that hard, especially for the incredible makeup people they had. I mean, if you can create hundreds of orcs, I hope you can dye eyebrows to match someone's wig. Oh well, maybe they just overlooked it.
