Hollywood director that worked on Titanic and Avatar, James Cameron took the experience of his life as he recently dove to the Earth's deepest point, in the western Pacific Ocean's Marianas Trench.

Cameron reached a depth of 35,756 feet (10.91 kilometers) and spend at the bottom about three hours, despite he planned to spend up to six hours on the sea floor. RELEASE, RELEASE, RELEASE! were the last words Cameron uttered before beginning the dive, according to a Twitter post from the expedition.

Cameron collected samples for research in marine biology, microbiology, astrobiology, marine geology and geophysics, the organization said. He also spent time filming the Marianas Trench, about 200 miles southwest of the Pacific island of Guam.

The scale of the trench is hard to grasp - it's 120 times larger than the Grand Canyon and more than a mile deeper than Mount Everest is tall. The trip to the deepest point took two hours and 36 minutes. But Cameron's return aboard his 12-ton, lime-green sub called Deepsea Challenger was a "faster-than-expected 70-minute ascent," according to National Geographic. A helicopter spotted the submersible bobbing in the water and it was brought aboard the ship by a crane.

There were no immediate reports regarding Cameron's well-being. A medical team was present when Cameron, 57, emerged from the sub, according to the expedition.

That must have been amazing!
