i think the hitchhiker’s guide to the galaxy fits admirably into the different iterations of this story (radio show, book, television show, interactive text adventure, and now movie). it is more similar to the others than it is different, and i think it may be the only version where trillian is more than a sketch of a character.

considering how well the movie has done, and the various references to going to the restaurant at the end of the universe at the end of the movie, i would be more surprised to not see a sequel than to see one.
