This is one of my favourite sagas. The author, Frank Herbert has a wonderful way of involving his readers (yes, I know he is deceased). The movie made of the first of his books in this series is quite a good attempt. The acting was ordinary in some places, but a remake with followup movies to continue the saga would make a great counterpoint for the Star Wars series.
I have recently purchased the three part remake of the movie DUNE. I found this very different from the DeLaurentis version. The characters were portrayed in quite a different manner. Some things, such as the make-up on the Baron, seem to have been toned down for a wider audience. The disease that destroyed the baron's body was supposed to cause blisters on his face making him look horrid. These were not visible.
Overall the acting was improved and the general story closer to the book in some areas. This allows the three part series to sit as a good yarn in its own right.
It was followed up with Children of Dune which is the third book in the series. It would have been nice to see elements of Dune Messiah incorporated into the two sagas to act as a bridge rather than jumping about 20 years. However, After seeing them several times they have grown on me.
Worth a viewing if you have half a day to spare.
I may put my thoughts together in the near future and attempt a review of the six books in the complete Dune saga - I have not yet read all three books Written by Frank Herbert's son although I have them on my bedside table.
