Here she shares some suggestions for casting the leads in an adaptation of Touched:
I know of authors who cut out pictures of famous actors and actresses so they can better understand what their characters look like. I'm not one of those people, as I've slowly come to learn that readers care less about the color of one's hair and eyes than what makes a character tick. In selecting characters for my movie, I'd love to find characters who are actually young, since the two main characters are 16 and 17. The viewpoint character, Nick, has led a very sheltered life, so there is a lot of innocence there. I see him looking like the young actor David Lambert. The main female character, Taryn, who has a little more worldly experience, would be Chloë Grace Moretz. Neither are household names yet, but they're young, give them time!Learn more about the book and author at Cyn Balog's website.
Nick's mother would be Zooey Deschanel. The expression she wore during all of The Happening is the exact expression I'd imagined Nick's immature, bed-ridden, guilt-ridden mother would have. And Frances McDormand would make a great grandmother-- she's caring, but fair, and not overly emotional.
