Here is another update...
Here is a list of movies with diving content (divers in the water) this is primarily a list of Hollywood drama type films, a few documentaries of note are included.
I used IMDb to find movies tagged with Diving or Scuba. Synopsis of the films are likewise from IMDb.
Films with ??? after the date may or may not have actual footage of divers. If anyone can verify weather or not there is dive footage in a film please post it here.
Star ratings are based on Scubaboard posts recommending these films, as well as diving content.
