Also, Rhea McAdams is supposed to have mixed European/Asian features, at least according to her description in The Body Electric. I'm thinking maybe Lexa Doig for her, as a nod to the fact that she's played an android before (on Andromeda).
Interesting, that certainly wasn't the vibe I got from Immortal Coil back in the day. I was picturing someone more along the lines of Bryce Dallas Howard or someone like a modern day Maureen O'Hara.
On another note, how about Maury Chaykin for Ganz?
