 It was used in the scene where Kong is shaking the sailors off the log, as well as the scene where Kong pushes the gates open.The Williams process did not use bipacking, but rather an optical printer, the first such device that synchronized a projector with a camera, so that several strips of film could be combined into a single composited image.Through the use of the optical printer, the special effects crew could film the foreground, the stop-motion animation, the live-action footage, and the background, and combine all of those elements into one single shot, eliminating the need to create the effects in the camera.
