Another idea=Mathew Stover Not as lead writer, his books don't seem to me like movie material but I feel that he wrote the Vader/Jaycen transformation pretty damn well. I unfortunately read ROTS before the movie. I think he could give good input into making the darker scenes gain traction with the audience. All of his books made me understand the thoughts of the baddies, almost to sympathy. I dunno if that is good movie material though.
