Hopefully, some day, these books are done well on the big screen. If I were casting director, here are the folks I'd want to bring this story to physical life. Characters that appear in multiple stories are only listed once, in the book that they first appear.
*Note: The cast is deliberately racially diverse keeping with the racial diversity a universe where the human population has spread beyond earth. I've chosen actors that I think embody the persona of character first and their described features second, so not all cast members embody Herbert's original descriptions.
