I cannot think of a case where the book was not better than the movie, but I still enjoy watching the movies to see how they depict what was written. One of the worst cases of "movie alteration" was with The Naked and the Dead, where the wrong deaths occurred. Also related to this is illustrators (especially of paperback covers) who do not bother to read the book before doing their drawing.
MY favorite paperback cover of all time was on a Zane Grey's "Nevada Smith".
Feller had a revolver - I think cap and ball, but maybe cartridge - firing - with the cases just flying out to the side.
I wish I'd kept it.
