A bit incomplete... Leto - Liam Neeson or maybe even Pierce Brosnan...Liam Neeson looks the part, but I think Brosnan has the intensity. Paul - Er... Jessica - Lena Heady. I can't remember who said it, but that's good casting. Duncan - Clive Owen is basically Duncan from God Emperor...Daniel Craig would be a bit more noble in the role, though, and considering this is Dune, he's not as brooding as he is in later novels. Maybe even Aaron Eckhart? Thufir - Anthony Hopkins. Gurney - Viggo Mortensen. Baron Harkonnen - It would be cool to see Jim Carrey done up as the Baron, but he doesn't have the voice. He definitely can't just be a bigger actor. Maybe we can delve into the music industry and steal Till Lindemann? Feyd - I'd like to see Heath Ledger do this...but it can't happen. Maybe a villainous turn for Ed Norton? Rabban - Mickey Rourke? Benicio Del Toro? Piter - I can't think of someone off the top of my head. Alan Rickman? Shaddam - I like the idea of Hugo Weaving. Fenring - Richard Roxburgh (courtesy of BobaMatt's suggestion) or a shorter, less mighty-viking Peter Stormare. Stilgar - I've chosen a Hurt...John Hurt. Chani - Sienna Guillory holds a soft spot in my heart. Irulan - Scarlett Johanssen.
