Ghostbusters is my One True Desert Island Movie. Others get moved on and off the list thanks to my lack of decision-making skills, but Ghostbusters has a permanent spot. I have an unholy love for that movie.

My personal favorite is the second book, Deep Wizardry, which is mostly set in the ocean and features an ancient megaladon shark (named Ed, no less) as one of the supporting characters.

Ooh. I wish I could have read that as a kid- I wanted to live in the ocean so much (except that then I couldn't have had a pony. Not that I had a pony anyway). Okay, any book where the action takes place underwater, I need to read. I'll have to hunt these down.
