Around the World Under the Sea is a 1966 science fiction film directed by Andrew Marton and starring Lloyd Bridges, with Marshall Thompson, Shirley Eaton, Gary Merrill, and David McCallum. It follows the adventures of a crew of the deep-diving nuclear-powered civilian research submarine Hydronaut making a submerged circumnavigation of the world to plant monitoring sensors on the ocean floor that will help scientists better predict impending earthquakes. Although Jules Verne is not credited by the filmmakers, his influence can be seen throughout the film.
