I recently read the first Dune book, and I liked it. I knew there was some movie version of it and looked around and found a 1984 movie, and other that I think is a series from the year 2000.
I haven't watched them yet, just a little from the beginning, and in both of them what I think is a member of the Spacing guild emerges from some kind of container. In the movie it talks with the emperor, tells him to kill Paul, and looks like a giant monster head. In the series it looks like a weird giant bat, and concentrates to make the space ship go into hyperspace.
My question is: Did the first book say how they looked like? All I remember is that is was a mystery. Was there some hint that they looked like that and I missed it? Is it made up? or are they using information from the other books?
Thanks.
