Cameron launched the project after seeing Robert Ballard's 1987 National Geographic documentary on the wreckage. Blueprints of the real Titanic were followed during construction at Fox's custom-built Rosarito, Mexico studio, where a hydraulics system moved an immense model in a 17-million-gallon water tank. During three weeks aboard the Russian ship Academik Keldysh, underwater sequences were filmed with a 35mm camera in a titanium case mounted on the Russian submersible Mir 1. When the submersible neared the wreck, a video camera inside a remote-operated vehicle was sent into the Titanic's 400-foot bow, bringing back footage of staterooms, furniture and chandeliers. On November 1, 1997, the film had its world premiere at the 10th Tokyo International Film Festival. ~ Bhob Stewart, All Movie Guide
