The 1984 movie was interesting, but had several discrepancies.
There was no Sonic Weapon/Weirding Module in the book, they had lasers, called ‘lasguns’.
The Guild Navigator interpreter would not have threatened the Emperor, he would have been immediately killed.
The Harkonnen Heart Ring was not in the book.
The child Bene Gesserit, Alicia, could not read minds...
However the costumes were great and were in keeping with the book.
I will admit that the book was very hard to follow for me but it was back in 1978 or 1979 I think. Hell I cannot remember what I went to the kitchen for just a few minutes ago. But I did read a lot of science fiction in the 1970s and this was supposed to be one of the majors.
I just didn’t see the premise of riding or taming giant worms to make sense.
Yeah the movie sucked and now that there is a re-hash I won’t be watching. Maybe I will re-read the book and see if it got better with time.
