Now that I saw the trailer I can tell you that:
1. The filmmakers never read THG; or
2. The filmmakers never loved THG.
Arthur Dent is all wrong (too young), Marvin is all wrong (too cgi and too streamlined), Zaphod is all wrong (too few heads), Trillian is all wrong (too interested in Arthur).
This is all wrong. I won't be seeing it.
The BBC version was really bad....I preferred the visions in my head. It is hard to beat my imagination. Although, I think they did a great job with Fear & Loathing in Las Vegas. I walked out of the theater feeling like I had taken drugs.
I haven't read the books in years. I think I'll reread them in time for the movie. LotR bothered me some at first because it wasn't my vision of the books, but I now love the movies almost as much as the books. I'm going to give the movie a chance.
The script was based directly on DNA's writings for the MOVIE.
DNA said he did not want to just put the books on film. He wanted to adapt the story to film much in the same way that the other formats are tailored for each particular media type (He didn't really set out to do it that way years ago he said it just sort of happened). You should listen to the original radio series or the records. They are ALL different from the books.
Anyhow I like the idea this will be different. It fits the series exactly. If you do not think so, read the introduction in "The More Than Complete Hitchiker's Guide to the Galaxy." DNA tells the story of how all the versions are different.
