The superb question from our financially oriented Canadian friend is this:
Was JEJ, as pure voice actor for DV, a creative or financial decision?
My supposition is this:
True, SW had no budget and voice is cheapest.
True, JEJ didn't cost much, one way or another.
Lucas is, I think, I believe, please help me you SW historians, on record as admitting DV was modeled on DOOM.
This leads me to believe, on balance, that we are talking about a deliberate creative decision: the mystery of a faceless villain [with a compellingly villainous voice]
Marvel readers [forgive me, but I think our Canadian friend is a DC chap] know the long history of the dramatic power of a faceless DOOM.
SW fans know DV and that voice, even better.
No Tom Cruises or RDJ's, please.
