The re-release of James Cameron's 1997 theatrical masterpiece Titanic is supposed to be one of the best 2D-to-3D conversions that any filmmaker has ever attempted. Of course, aside from the updated visual presentation, nothing in the acual movie itself will change. It will be the same experience as going into a movie theater 15 years ago, with the addition of 3D glasses. Or will it?
Something that no human beings would ever actually notice unless they knew specifically about this change will be altered in the movie. In that iconic scene where Rose is lying on a piece of driftwood and staring up at the stars, the sky is not scientifically accurate. That fact was apparently noticed by astronomy expert Neil deGrasse Tyson. Because Cameron is such a perfectionist, he wanted to make sure that as long as he was re-releasing the film, he could correct this error that probably only Tyson would ever noticed.
Cameron was quoted as saying that Tyson "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 ... So I said ‘All right, send me the right stars for that exact time and I’ll put it in the movie.'" And so he did. See if you can spot the difference when you head to the theaters to re-live movie history.
