For Miranda Kadohata; I was kinda picturing Thandie Newton(Brit accent comes as standard extra)
Odd, since she's African-British, and Kadohata is Japanese-British. I'm with Keith that the actress who starred in Battlestar Galactica: Razor
would be a fine choice -- well, if she were a decade or so older.
My thought for Bart Faulwell wasDerek Jacobi.
Interesting thought, but he's way too old, unless you're imagining him from the '80s, say.
