Filmmaker, James Cameron has always been fascinated with the luxury ocean-liner, the Titanic, and its ill-fated maiden voyage (to such an extent that he made the multi-award-winning blockbuster film in 1997). In 2001 Cameron and his friend and actor Bill Paxton (who also acted in the feature film) sought to find and document the ship's final resting place at the bottom the the Atlantic Ocean and this documentary charts their progress, using 3-D cameras.
