Ghosts of the Abyss is a 2003 American documentary film produced by Walden Media. It was directed by James Cameron after his 1997 film Titanic. During August and September 2001, Cameron and a group of scientists staged an expedition to the wreck of the RMS Titanic. They dived in Russian deep submersibles to obtain more detailed images than anyone had before. Using two small, purpose-built remotely operated vehicles, the documentary offers glimpses into the Titanic wreck and, with CGI, superimposes the ship's original appearance on the deep-dive images.
