Guam - Oscar Award-winning filmmaker James Cameron is on Guam for the role of a lifetime. He is gearing up to explore and conduct research at the bottom of the Marianas Trench, the deepest point on Earth.

Only one other person alive has explored Challenger Deep in the Marianas Trench, but Cameron, the director and National Geographic explorer has brought a team of scientists from across the planet with him. In partnership with National Geographic and Rolex, Cameron in the coming days will descent into the trench in a submarine he co-designed.

It's something he says he's dreamed of doing entire life. Cameron, an avid SCUBA and free diver is excited to see what life is like seven miles down and says it's important for the sake of science that the submarine be manned. "It's not enough just to get the images. Images are part of the story. The human race is exploring these places, not a robot. Robots can't do that...we can have Google Maps and satellites, but the second you go a few centimeters below water, radio signals go down. We've got to go down and look!" he shared with KUAM News.

Cameron is waiting for calmer seas to make the trip to the ocean floor but hopes to depart the island in time to make the Titanic 3-D movie premier in April.
