Krysten Ritter for one of the Paranet women from White Night.
Giamatti's a bit old for Butters.
Giamatti was my first pick for Butters back when I started this thread. That was because there's another guy who's even better but I couldn't (and still can't) remember his name. Kinda reconsidering that, though. Maybe I'm mentally aging him downwards to make him a better fit for Andi (and for his brief physical descriptions in-text).
Someone suggested Jeremy Irons for Vadderung. I think he works better as post-strangulation Nicodemus. Got the voice for it. Kris Kristofferson way better for Vadderung.
Sir Anthony Hopkins for Ebenezar? Oh, hell no. Speaking voice not brusque enough, too whimpy.
Need someone who looks like the late Richard Attenborough (I've always visualized Ebenezar this way) but who sounds like Robert Duvall. Actually, belay that. Robert Duvall would be a good Ebenezar--and he does a variety of accents as well.
And Samantha Mumba MUST be Tera West. No one else will do.
