Dragon :
*I'd like to share a revelation that I've had during my time here. It came to me when I tried to classify your species and I realized that you're not actually mammals. Every mammal on this planet instinctively develops a natural equilibrium with the surrounding environment but you humans do not. You move to an area and you multiply and multiply until every natural resource is consumed and the only way you can survive is to spread to another area. There is another organism on this planet that follows the same pattern. Do you know what it is? A virus. Human beings are a disease, a cancer of this planet. You're a plague and we are the cure. *

New Vegas had a ton of celebrities... and they all did a great job. But that wasn't made by BGS.

Whatever, Max von Sydow is the man, and perfect for the Greybeard role. Honestly, of all the actors I would put him in that spot immediately, ever since seeing him as King Osric in Conan the Barbarian....it just fits.

He should be the voice of a dog or animal like George Clooney and Sparky the Dog on South Park.

Bring a big name actor to the table, have him say 'woof' twice, and call it a day.

Plus i wouldnt mind hearing a scottish-esque sounding dog bark.

This.
