Normally I don’t cast actors in the roles in my books, they’re just who they are, but each of the aspects is an actor to me. If you look really closely, you might be able to guess who they are, because they’re all famous actors. For instance, JC’s personality is based on the sort of characters Adam Baldwin tends to play (Jayne Cobb, John Casey, etc). Ivy was based on Gwyneth Paltrow.
