Cameron said his trip for the TV show "Last Mysteries of the Titanic," which premieres July 24 on cable's Discovery Channel, was his last.

Utilizing newly developed technology, Cameron and his team present what may be the best look yet at the sunken ship's interior.

This expedition, Cameron's most comprehensive dive yet, attempts to uncover clues and to shed some light on some of the Titanic's interiors such as the Turkish Baths -- the best-preserved and most opulent remaining space in the ship's interior; Scotland Road -- the crew's quarters; the first class cabins -- still containing some personal possessions of the Titanic's wealthy passengers -- and the cargo holds, which housed the luggage of the ship's first class passengers.

Re-enactments were filmed using sets built during the production of Cameron's feature film, "Titanic."
