Filmmaker James Cameron has long been fascinated with the ill-fated maiden voyage of the great ship the Titanic, and he used the story as the backdrop for his most famous and successful movie. In the summer of 2001, Cameron and his good friend Bill Paxton (who appeared in Titanic) joined a group of scientists, maritime historians, archaeologists, and deep sea explorers for a daring experiment -- to find and document the Titanic's final resting place at the bottom of the Atlantic Ocean. Cameron brought along a film crew equipped with state-of-the-art 3-D cameras to document the voyage, and Ghosts of the Abyss offers a detailed look at their search for the Titanic, as well as imagining what the final hours for the crew and passengers must have been like. The initial release of Ghosts of the Abyss was limited to big-screen IMAX theaters and movie houses specially equipped to show 3-D features.
