Back in the 1980's, I read a trilogy written by Douglas Adams:
Hitchhiker's Guide to the Galaxy. I remember it as a very funny series of books, right up there with the writings of Tom Robbins and Rob Brezsny.
The Hitchhiker's Guide to the Galaxy is a British film and the distinctive brand of British humor shines. The film begins with dolphins (the most intelligent species on earth) attempting to tell humans that the world is coming to an end. The earth is being demolished in the same way houses are torn down to make way for freeways in the name of progress. The character Arthur Dent is saved by his best friend who turns out to be an alien (played by Mos Def). They hitch a ride on a passing spacecraft, and thus begins the adventure for which the Guide is necessary.
The space creatures are grotesque, but in more of an amusing way than anything scary. The animated Guide illustrates what you need in space (a towel for one thing). The whole film is very funny, and the ending sweet and sentimental. It all works and I don't want to give away what happens. Just believe me when I say rent it; you won't be disappointed if you want a good laugh. I saw it at my local dollar theater, but it will probably be available to rent soon.
