[/I]Suppose this had happened; would the original trilogy have worked with Dooku as the films' primary villain, as opposed to Vader? Obviously, the matter of Luke and Leia's heritage would have been handled differently, but what of the rest of the OT's plot. Would fans have responded to Dooku as they did Vader?
So, Dooku/Christopher Lee would be henchman to Tarkin/Peter Cushing? That would appeal to Hammer fans, but I don't think it would have intrigued audiences the way the look, sound and mysteriousness of Vader did. Not even close.
