Ebert: Rolling Stone: TV Guide:

Warning, minor plot points revealed!

OK.  I loved this movie.  It's kind of like a Sci-Fi Monty Python movie that was directed by Terry Gilliam.  

I will admit here (to my great shame) that I have not read the book, The Hitchhiker's Guide to the Galaxy.  Or any other Douglas Adams book for that matter.  

I have read that the film is pretty faithful to the source material and fans seem to like it.  

I liked it for reasons like the special effects were superb for a comedy.   The actors were all hilarious, especially Sam Rockwell as Ex-President of the Galaxy, Zaphod Beeblebrox.  There's cameos by Bill Nighy and John Malkovich.  Mos Def and Zooey Deschanel play the best friend and love interest for the hero everyman Arthur Dent who is played by Martin Freeman from the British TV show The Office.  Alan Rickman also lends his voice to a depressed robot.

The film is on the surface about a guy who gets off Earth just before it is destroyed to make room for an interstellar construction project.  The rest of the film follows him as he meets and sees some of the beings that run the galaxy, reunites with a lost love and searches for a good cup of tea. 

I'm not going to go on and on about this one because unlike most movies this will have a very limited niche audience.  You've probably already seen it if you're interested and are not going to see it otherwise.  So at best, I can say that if you're really wasted one night and looking for a weird little funny movie to kill some time then check this one out for sure.  It should do.
