The Star Field Was All Wrong
In his email, Tyson explained that the star field Cameron had created for one of the climactic scenes was effectively all wrong. Cameron explained: “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 the piece of driftwood and staring up at the stars, that is not the star field she would have seen.”

Cameron then admitted that with his reputation “as a perfectionist,” he “should have known that and should have put the right star field in.” He wasted no time responding to Tyson. He wrote: “All right, send me the right stars for that exact time, and I’ll put it in the movie.” And just like that, Tyson sent his corrections.
When Titanic was re-released in 3-D in 2012, the new version of the star field was inserted. (Not that you likely noticed.)
