No information has been revealed about which actors will be playing which parts. The GIA speculates, however, that Donald Sutherland will take the role of the old man "Charles," the demure woman seen in the trailer will be voiced by Ming-na Wen, and that James Woods will play the villain. Hopefully, future announcements from Square will put to rest our endless speculation (and betting pools).
