Two years after completing the first one-person voyage to the deepest part of the ocean, Hollywood director James Cameron's 3D underwater plunge is set to splash into theaters in the US this Friday.
Deepsea Challenge chronicles Cameron's submarine descent into the western Pacific's Mariana Trench, a barren underwater moonscape where "squid worms" and other creatures flit past the window on the record-breaking odyssey.
The Titanic and Avatar director said Monday at a screening at the American Museum of Natural History in New York that he has been "continuously inspired by the oceans," since a boy.
"I'm a curious monkey and I need to go and see by myself," he told some 1,000 fans, many of them children, who came to see the film at the museum's LeFrak Theater.
The seven-mile (11-kilometer) voyage to the Challenger Deep valley of the Mariana Trench, which lies southwest of Guam, was the first manned expedition in more than half a century and the culmination of more than seven years of planning.
The March 2012 journey took two hours and 36 minutes, according to the mission organized with National Geographic.
It was carried out in a submarine christened the "Deepsea Challenger," which was equipped with 3D cameras and powerful lights to illuminate the sunless depths.
