Paul's younger sister. I thought that the film's appearance for this character was alright, albeit not very interesting. Didn't like her voice either. Wanted to give her subtly creepy look, as per the novel's description of her.
Next up is Paul's father, Duke Leto Atreides. I feel that Lynch's film at least aesthetically did the character some justice, and casted an actor that looked the part well. One thing that I really wanted to strive for in this series was to make uniforms all look consistent, but different enough for some individuality.
