I was recently reading a short article about dive movies and movies which have scuba or snorkeling scenes.  Below are a few I know of, but I will bet there are many more.
Here is a partial list:
Thunderball, Fool’s Gold, Into the Blue, Men of Honor, Open Water, The Abyss, The Cave, The Deep, Aquatic Life with Steve Zissou, The Undersea World of Jacques Cousteau.

Send us (as a comment) additional movies or documentaries and we will put them all in a giant list.  Then when you can’t get under the water you can get one of these movies to help satisfy you need to dive. 
Everyone  submitting a comment will be entered to win a HD DVD Screensaver, The Living Aqaurium.  The winner will be drawn at random so include so way to contact you (NO we will not give or sell ANY info about you).
