Yes. The HHGG movie gets a lot of flak for not following the books
... and indicates a "fan" who hasn't actually read their history. The movie doesn't match the book, true. But the books don't match the radio series. Hell, there are different *versions* of the radio series, and none of them match the book (or the movie). And Adams liked it that way - as far as he was concerned (at least according to the preface on my copy), there *is* no "right version" of Hitchhikers.
Now, that's not to say that the movie is a cinematic masterpiece. But it's a good silly romp, and frankly a cinematic masterpiece wouldn't have done the subject justice.
