I tend to be with those who think the voice should be an unknown, since having one that is too recognizable brings along potentially unwanted baggage. But that said, the one voice I can think of that I would've liked to hear do Smaug belongs to an actor who, alas, is now dead: Andreas Katsulas. Regardless of accent, I think the quality of his voice would have been wonderful (somehow, I keep thinking of G'Kar in the lift on Babylon 5, holding out a blood-dripping hand, chanting "Dead... dead... dead...").
