With Titanic being re-released in theaters in 3-D this week, the 1997 blockbuster's director, James Cameron, says he's made just one change to the film, and almost no-one will realize it. The change stems from celebrity astrophysicist Neil deGrasse Tyson noticing in the original movie that when Kate Winslet's character, Rose, is clinging to a piece of debris in the ocean under the night sky, the left half of the starry heavens was a reflection of the right half. Tyson contacted Cameron about it, as the director recounted to Discovery: "Neil deGrasse 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 a 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 known that and I should have put the right star field in." Talking about the same issue to the British magazine Culture, Cameron said, "So I said, 'All right, you so and so, 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."
