It all started in 1918 with the first film to feature underwater footage: Fred William Stephenson's 20,000 Leagues Under the Sea. Ever since, Hollywood has headed to the clear blue waters of the Bahamas to shoot underwater scenes for three simple reasons: its proximity to the U.S., excellent visibility, and exceptional value.

Like many other locations that still bear the reminders of film sets, Nassau is no different, except that the sets are underwater. Today, divers can submerge on wrecks like the Tears of Allah from James Bond's 'Never Say Never Again' and the Vulcan Bomber from 'Thunderball'. The Cessna plane that crash-landed in Jaws IV now rests permanently on the sea floor. You can view the cockpit of the DC3 plane wreck from Into the Blue. If you're taking the Underwater Hollywood backlot tour with Stuart Cove's Dive Bahamas, you can get your picture taken at your favorite film site and hear some of the behind-the-scenes stories.

And, with the resident marine population that also frequents these film sets, you never know who you might see there.
