Someone brought up Charles Dance in the comments of the AV Club article about this, and while I personally think he isn't right physically for the role, I'd much rather they go that route than digitally recreate a dead actor. Whether or not they can pull it off, I'm a little squeamish about it ethically. It's like that Audrey Hepburn commercial for . . . I want to say . . . Chocolate? I found that whole posthumous endorsement deal thing really unsettling. Anyway, I have to think that to do this in an actual movie would set a potentially dangerous precedent.

aside from all that, even though I don't like him for Tarkin, I'd love to bring Dance into the saga in some other capacity. He'd be great.
