Today's research has thrown up this 2003 documentary. A bit of weekend film watching is to follow I'm sure. Here's the trailer.
Ghosts of the Abyss is a documentary film released by Walt Disney Pictures and Walden Media. It was Disney's first film produced in 3-D and was directed by Academy Award winning filmmaker James Cameron after his Oscar winning film Titanic. It consists of Cameron and a group of scientists sailing out to the wreck of the Titanic, and then going down to get closer than anyone has before. With the help of specially created cameras, Jake and Elwood, the audience too can see inside the Titanic and with the help of CGI, people can see how it would have originally looked.
Also along for the ride Cameron invites friend and actor Bill Paxton who played Brock Lovett in the 1997 film. He narrates the event through his eyes. The film itself was produced for IMAX 3D during the Summer of 2003. It was also nominated for a BFCA award for Best Documentary. The submersibles Mir 1 and Mir 2 carried the Ghosts of the Abyss team on twelve dives.
