If he would do it, about the only person I could ever see as Pentadourn is Morgan Freeman. In fact, when I was reading the book to my mother, she even said he felt like Morgan Freeman. So there you go. Mr. Freeman- if you ever see this? You are 100% Pentadourn and will always be Pentadourn to me.
Tchéky Karyo is the only person who could play Baron Gustav Rothschild in The Raveners. He has a perfect mix of stern power. In fact, I thought of Karyo when I first started writing the character. He has a small part in The Way as a policeman and it really inspired me when I was creating the Rothschild character. He just looks strong and very capable. And his accent is like butter!
