When "Titanic 3D" arrives in theaters on Wednesday, it won't just feature an extra dimension, but also a scene change. That's according to director James Cameron, who -- when his name isn't being used to prank journalists into writing about "Prometheus 2" -- is a period-specific perfectionist, right down to the very last star.
Speaking with the UK magazine Culture (via Contactmusic.com), Cameron revealed the one slight fix he made to the 1997 blockbuster: the night sky.
Cameron was urged to make the fix by Neil deGrasse Tyson, an astronomer who questioned the position of the stars during "Titanic's" climatic scene.
"So I said, 'All right, you son of a bitch, send me the right stars for the exact time, 4:20 a.m. on April 15, 1912, and I'll put it in the movie,'" Cameron said. "So that's the one shot that has been changed."
(Somewhere, George Lucas turns away from his laptop and mutters, "Amateur.")
Those stars aren't the only ones that have changed in the "Titanic" universe -- at least off-screen. During press rounds for "Titanic," actress Kate Winslet summed what the last 15 years have done to her and co-star Leonardo DiCaprio.
"Leo's 37, I'm 36--were 21 and 22 when we made that film," she told the television show "Daybreak." "You know, he's fatter now -- I'm thinner. It's true though!"
Aww, Rose always was a spoiled little brat, but that's why Jack loved her. May those star-crossed lovers live forever in your imagination -- this time with a proper star field.
