But like all rules, I don't follow this one specifically, and there are two roles in the Forgotten Stars books that I have mentally filled with specific actors. One is the stern, business-like, and highly competent Lieutenant Penda Rasharri, who serves as an unplanned mentor to Princess Tariana Osono, giving the Princess her first lessons in what it is to be a Stardancer. I'm not sure why, but the actor I've always had in my mind as playing Rasharri is Taraji P. Henson.
But here's something weird: via SamuraiFrog's blog, I literally just learned -- after loving Henson's work on Person of Interest for the first three seasons -- that the 'P' in her name stands for Penda.
(And who is the other character for whom I've had a specific face in mind? Hmmmm...any guesses. folks who have read Stardancer?)
