It's been nearly fifteen years since Titanic has come out. This is upsetting, for the obvious reason: you remember seeing it as a tween, and that means you're getting old. A lot of things have changed: Kate Winslet is the new Meryl Streep, and Leonardo DiCaprio is fat now, according to the new Meryl Streep. So you'd imagine a lot of changes would be made for Titanic 3D, the seriously unnecessary rerelease of the shipwreck epic that captivated the world and took up two whole VHS tapes in 1997. But actually, Titanic's not changing that much: a ship's prow here, a sweaty sex hand there, and you've got some X-axis action!
In fact, the only major change was prompted by the most bitchin' astrophysicist of our time, Neil deGrasse Tyson. Naturally, he realized that the stars framing Winslet's head during her near-death were all wrong for the spring of 1912, as he told James Cameron in an email:
"…Neil deGrasse Tyson, who is one of the U.S.' leading astronomers, sent me quite a snarky email saying that, at that time of year, in that position in the Atlantic in 1912, when Rose is lying on the piece of driftwood and staring up at the stars, that is not the star field she would have seen, and with my reputation as a perfectionist, I should have know that and I should have put the right star field in.
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.' So that's the one shot that has been changed."
Here's a video of Tyson relating the story at the Cosmic Quandries event in 2011:
I always knew something was missing from that movie.
