I'm not, despite allegations to the contrary, a big geek. That is, I don't salivate over whatever Star Trek show is on and I will not see the next Star Wars movie when it comes out this summer. I'm intrigued by Hitchhiker's Guide, if only because I remember the book was laugh-out-loud funny.
If you are a geek, and you haven't seen Galaxy Quest, you're missing the best version of Star Trek to never feature Spock.
And if you ever wanted to get a glimpse behind the mask, I truly recommend The Darth Side: Memoirs of a Monster. Start reading from the bottom entry up.
