Ah, fair, I wouldn't describe his voice as 'beautiful' or 'elvish'. But Tony Stark did call him "Legolas" in The Avengers (on account of his bow and arrow), so....there is that....
And you guys...this is all Nick's fault, but now I really, really, really want Jared Padalecki to be an elf for no reason at all, so you've got your choice of Rhogrin, Ecthelion, or Caranthir, but I'm probably gonna wind up nominating him for all three roles just because at this juncture. Fair warning.
Okay, okay...not really "no reason at all." I could see him taking down Gothmog. And he's pretty enough for CW casting, so...yeah.
