I find Wikipedia a great data base giving information which no other encyclopedia would give.
I do my bit when somebody tries to mutilate (not edit) an article by, for instance, deleting whole paragraphs or links just because he/she does not like it.
20,000 Leagues Under the Sea is an American silent film directed by Stuart Paton and released on December 24, 1916. Based primarily on the 1870 novel Twenty Thousand Leagues Under the Seas by Jules Verne, the film 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 viewing chamber called the "photosphere", a 6-by-10-foot (1.8-by-3.0-metre) 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
