Kinda sorta not really. The movie is based on Hitchhiker’s Guide to the Galaxy a little, but it’s a very loose adaptation. A lot of the story and humour has been adjusted for a more American audience in the movie. Read the books, though! They’re a fairly light read and rather short, so they aren’t massive commitments. The humour may go over your head a little, depending on what your sense of humour is. It’s very (VERY) British at times. Also, keep in mind the age of these books. They’ve aged very well, but the first was written in 1979.
Yeah, I’m under the impression that the last two are a bit darker than the first three. Even if I dislike them, which I probably won’t , I’ll still read them.
Oh, I’m also going to be adding Dark Omens to my reading list. Just sayin’.
