Dune: great book, lousy movie. Maybe someone should take Dune and make it a trilogy.
Check out both SCI FI mini series of both Dune and Children of Dune. The writing and acting in both is superb though the sets in the first can be a little lacking. Much better desert cinematography in the second. The actor that played Xavier in the XMEN prequel movie plays Leto in the Children of Dune(intense acting even then for one so young). The series were shot in High Def and 16:9 and the sound editing in discrete surround(not matrix dolby prologic surround) is a work of art. DTS for Dune and Dolby 5.1 for Children of Dune on the DVD’s and of course the Blue Rays have much higher resolution video and sound!
