I'm hoping HBO and Ron Howard get this TV show going. The fans WANT to see it! and it'd make a great show for non-readers to watch. Following is my personal opinion on best Actors/Actresses to play key roles in the show. I'm hoping someone somewhere reads this post and thinks the same way. Ka-Tet Roland Deschain: Anson Mount Anson Mount best known for the role of Cullen Bohannan in TV show Hell on wheels. Eddie Dean: Aaron Paul Aaron Paul is best known for his role as Jesse Pinkman in the hit TV show Breaking Bad. Susannah Dean: Naomie Harris Naomie Harris is best known as the new Money Penny in the Bond films and a prolific TV show actress. Jake Chambers: Chandler Riggs Chandler Riggs is best known for the role of Carl Grimes in the TV show The Walking Dead.
