The Poseidon Project

The Poseidon Project is a 2013 documentary film about the search for the lost Royal Navy submarine HMS Poseidon. The submarine sank after a collision off the coast of China in 1931. It was widely assumed to be still present in the Bohai Sea, 20 miles off the city of Weihai in China's Shandong Province until American author and scuba diver Steven Schwankert discovered that she had been salvaged by a Chinese salvage team in 1972. Schwankert's work and the history of the submarine and its crew is the subject of The Poseidon Project. The film was directed by British brothers Arthur Jones (film director) and Luther Jones.

Synopsis
The film is about Beijing-based author and scuba instructor Steven Schwankert's search for the British submarine HMS Poseidon. Schwankert was looking for interesting wrecks to dive in northern China when he found Poseidon on a list of unexplored dive sites. He spent the next six years working on the project, bringing together research in China and the UK to piece together the history of the submarine.

Poseidon collided with a cargo ship off the coast of China on 9 June 1931. Thirty-one of the submarine's crew managed to scramble into the water before the submarine sank to the seabed 130 ft (40 m) below. But 25 were trapped inside. The submarine hit the headlines within hours because five men managed to escape from the submarine using the new Davis Submerged Escape Apparatus. They were the first people to escape from a downed submarine using proto-scuba devices.

The film charts Schwankert's efforts to examine the escape and the accident in unprecedented depth. It also follows him as he uncovers the secret salvaging of the submarine in 1972 by one of China's new salvage teams. The story is also told in Schwankert's book Poseidon: China's Secret Salvage of Britain's Lost Submarine.

Production
Arthur Jones and Luther Jones shot the first scenes of The Poseidon Project in Weihai, China in early 2009. Several return trips to Weihai ensued as Steven Schwankert came closer to discovering the fate of HMS Poseidon, and the location of the British cemetery that was originally located off the coast on Liugong Island. In China, other filming took place in Beijing and Shanghai.

Further scenes were shot in the UK, specifically at Gosport's Royal Navy Submarine Museum, at the Dock Museum in Barrow-in-Furness, at the National Archives in Kew, London, and in and around south London, where the grave of Poseidon escapee Patrick Willis was assumed to be located.

Postproduction took place during 2012 and early 2013. The Poseidon Project premiered at the Hoboken International Film Festival on 3 June 2013.
