James Cameron went from complete isolation seven miles under the sea Monday to the cameras and crowds of the "Titanic 3-D" premiere in London on Tuesday, sharing the red carpet with lovely creature Kate Winslet after leaving the tiny shrimp-like critters that had been his only visible companions at the bottom of the Pacific Ocean's Mariana Trench.
The 1997 film, which won 11 Oscars, including best picture, is being re-released in 3-D around the 100th anniversary of the Titanic's doomed maiden voyage, which ended with the ship's sinking on April 15, 1912.
"One of the reasons I made 'Titanic' was that I was fascinated by deep sea exploration," the director told reporters at the premiere, held at the Royal Albert Hall. "It was an opportunity to dive in a submarine very deep at that time."
"The 3-D enriches all of 'Titanic's' most thrilling moments and its most emotional moments,” said Cameron, who attended with wife Suzy Amis on his arm. "It kicks the whole experience up to another level.”
Winslet, who starred with Leonardo DiCaprio in the movie, joked that she would rather look away than see herself nude in 3-D.
"I'm not going to look, I'll be in the bar by that point," she said.
Cameron has visited the wreck of Titanic, around 12,600 feet below the sea, 35 times in his history of 72 deep-sea submersible dives.
On Monday, more than 36,000 feet undersea, "My feeling was one of complete isolation from all of humanity,” Cameron told reporters shortly after the dive. "I felt like I literally, in the space of one day, had gone to another planet and come back. It's been a very surreal day."
Other cast members spotted at the premiere included Billy Zane, Bill Paxton, Frances Fisher, Rochelle Rose, Jason Barry and Bernard Hill, who played ship Capt. Edward James Smith.
"Titanic 3-D" opens April 4 in U.S. theaters.
