James Cameron first received widespread acclaim as a movie director in 1984 with The Terminator, and has gone on to produce and direct many of the most successful films of all time (Aliens, Terminator 2: Judgment Day, Titanic, Avatar).
He is the executive producer of a new documentary, Deepsea Challenge 3D, which he produced in association with National Geographic.
It chronicles his passion for deep sea diving, as he pilots a solo submersible to the depths of the Pacific Ocean's Mariana Trench, the deepest point on Earth.
Deepsea Challenge 3D goes on general New Zealand release from 6 November.
