IMDB has a limited list with some interesting names besides Dinklage. Nathan Fillion! Gina Torres! Claudia Black! Yet these decent actors seem to be limited to vendors in the game. Hopefully they will be involved in some story lines. I know the list is incomplete though. I'm almost certain the voice of The Speaker is Bill Nighy (Victor from Underworld, Davy Jones from Pirates), but it could also be David Warner (Sark/Dillinger from Tron). And either someone is doing a great impersonation of Terrance Stamp (Zod from Superman II) in the Grimoire or it's really him. I just wonder why they would keep some names so secretive?
