James Cameron has safely returned from his journey to the Earth's deepest point.
The "Titanic" and "Avatar" director traveled to the bottom of the sea on Sunday to explore the south Pacific's Mariana Trench. He used a specially designed submarine called "Deepsea Challenger" to dive nearly seven miles as part of a National Geographic Society project.
The trip to the bottom took a little over two and a half hours, according to the Associated Press. Cameron tweeted about his historic experience.
"Just arrived at the ocean's deepest pt. Hitting bottom never felt so good. Can't wait to share what I'm seeing w/ you @DeepChallenge," he tweeted.
Cameron stayed at the bottom for about three hours before starting his return to the surface, which only took 70 minutes.
While exploring the trench, Cameron took photos and videos. The National Geographic reportedly said that Cameron's expedition was being chronicled for a 3-D feature film. Details were not immediately released.
Cameron, 57, reportedly has been an oceanography enthusiast since he was a child. According to the Associated Press, Cameron has made 72 deep-sea submersible dives, including more than two dozen to the Titanic wreckage, which was the subject of his 1997 hit movie.
