OMG, I am *such* a geek too! :D Labyrinth and Willow are two of my favorite movies (in fact, a friend sent me a link for the MP3 of the Willow theme!) I used to love The Dark Crystal (although I watched it with my kids and somehow realized the magic faded as I got bigger). Men in Black is awesome, and Close Encounters? Now that's classic!

I am disappointed not to see The Princess Bride or The Neverending Story on there, though. ;)
