A 30 ft (9m) model of the Loch Ness Monster was built for the film in 1969. The model included a neck and two humps and was taken alongside a pier for filming of portions of the film. Billy Wilder did not want the humps and asked that they be removed, despite warnings that it would affect its buoyancy. As a result, the model sank. The model was rediscovered in April 2016 during a Scottish expedition to find the Loch Ness Monster.
