Here she discusses her ideas on casting should her series ever be adapted for the big screen:
For me, it’s the characters who make a book, and their relationships that weave the story. I’ve never been big on physical descriptions in my books, yet I have a detailed image of each character in my mind as I write. A couple of months ago on my blog, I thought it’d be fun to have my fans weigh in on who they thought should play my characters should I ever get The Call from Peter Jackson. It was amazing to me how many different impressions readers have of my characters—and it was a lot of fun.Read the first few chapters of both Magic Lost, Trouble Found and Armed & Magical at Lisa Shearin’s website.
My main character, the elven sorceress and seeker Raine Benares, defends her friends by going toe-to-toe with the bad guys. She’s tough, yet caring, and you never know what she’s going to say or do next. I think Felicia Day (Buffy the Vampire Slayer and The Guild) or Miranda Otto (LOTR) would be excellent choices. For the hot and handsome elven Guardian, Mychael Eiliesor, Gerard Butler would be my hands-down choice. Vincent Irrizary would be excellent as the wicked sexy goblin and nightclub owner, Tamnais Nathrach.
For Raine’s cousin, the scion of the most notorious criminal family in the seven kingdoms, Johnny Depp gets the nod. Give this devilishly delicious man some elf ears, and he'd be good to go. Piaras Rivalin is a young, yet incredibly powerful elven spellsinger who manages to get tangled up in any trouble Raine finds. Josh Groban would be a perfect Piaras: big brown eyes, dark curls, killer set of baritone pipes. Sign this kid up.
For my villains, Richard Armitage who plays Sir Guy of Gisborne in the BBC's Robin Hood would make a wonderfully evil goblin grand shaman, Sarad Nukpana. A young Frank Langella would be a good casting choice for the power-hungry goblin king, Sathrik Mal’Salin. And for Sathrik’s younger brother, the exiled Prince Chigaru Mal’Salin, I think that Stephen Caudill (independent film actor of End of the Spear and The Other Side) would fill the bill nicely.
