20,000 Leagues Under the Sea is an American silent film directed by Stuart Paton, released on December 24, 1916. The film's storyline is based on the 1870 novel Twenty Thousand Leagues Under the Seas by Jules Verne. It also incorporates elements from Verne's 1875 novel The Mysterious Island. This was the first motion picture filmed underwater. Actual underwater cameras were not used, but a system of watertight tubes and mirrors allowed the camera to shoot reflected images of underwater scenes staged in shallow sunlit waters in the Bahamas. For the scene featuring a battle with an octopus, cinematographer John Ernest Williamson devised a vewing chamber called the "photosphere", a 6×10-foot steel globe in which a cameraman could be placed. The film was made by The Universal Film Manufacturing Company (now Universal Pictures), not then known as a major motion picture studio, and took two years to make, at the cost of $500,000.Film credit: Stuart Paton
