That movie is crud. The original BBC black and white production was more fun to watch. I will admit that their Zaphod Beeblebrox was worlds better than BBC's, but the rest of the characters, with the exception of Arthur Dent, were totally flat and boring and miscasted. And the editing was horrible! They made half the movie drag on longer than it should, and they cut out much of the interesting material from the book - like Ford Prefect talking the guy in charge of the bulldozers to take over for Arthur Dent by lying down in front of the bulldozers in the mud.

Basically, there's enough funny material in the movie to make it entertaining if you've never read the book or watched the BBC production. Otherwise, forget it.
