From the archives: James Cameron on deep-sea exploration

The Oscar-winning director of “Titanic” long had a fascination with life on the ocean floor. With cameras and deep-sea submersibles, James Cameron has brought the extreme environments of Earth’s oceans to movie screens in the documentaries “Ghosts of the Abyss“ and “Aliens of the Deep.” In this Jan. 30, 2005 “Sunday Morning” story, Jerry Bowen talked with Cameron, along with marine biologist Djanna Figueroa, seismologist Maya Tolstoy, and astrobiologists Tori Hoehler and Kevin Hand, about how exploring our planet’s most hostile landscapes can help in planning future manned missions to Mars and beyond.
