Walken was fine for me. The emperor played a smaller role in the film anyway.

The real miscast and the only problem in what is quite possibly one of the best adaptations we will ever see: Brolin as Gurney and Momoa as Idaho. They had the right actors in the wrong roles. I just don’t understand how you could flip those two pivotal characters like that. I really don’t think Momoa will be able to pull of a good mentat in the 3rd film.
