It's too bad the 2006 H2G2 movie didn't do well...I'd LOVE to see them make the rest of the books into movies. I loved the movie just about as much as I loved the books and the 80s miniseries. I wasn't sure about Mos Def as Ford at first, but he was an excellent choice. Great flick.
If you haven't read the books yet, I highly recommend picking them up, even if you're not a fan of sci-fi. They're hilarious and made from awesome.
