The expedition crew was composed of a Russian, American and Canadian who were operating off the Russian research ship Akademik Mstislav Keldysh. Footage of the wreck was obtained by two Mir submersibles, sometimes working together, that had been equipped with IMAX cameras and lights that generated 150,000 watts, capable of clearly lighting up the ocean floor. In the film, Eva Hart comments that prior to the Titanic striking the iceberg, her mother had commented that calling the ship 'unsinkable' was "flying in the face of the Almighty."
