The American astronomer accused the film director of having the wrong star field for the time and date, 4.20am on April 15, 1912, and claimed Cameron should have known better.
Cameron, in his turn, asked the astronomer to send the exact star map and after that he included it in the upcoming 3D version of the blockbuster film. According to The Telegraph, it is the only major technical change to the drama, which will be out in British cinemas on Friday.
Cameron, who recently returned from his voyage to the Mariana Trench, said: “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.”
“And with my reputation as a perfectionist, I should have known that and I should have put the right star field in,” he added. “So I said ‘All right, send me the right stars for that exact time and I’ll put it in the movie.”
Tyson has long been vocal about how Hollywood doesn’t always get science right in movies. During a 2009 panel discussion at St. Petersburg College in Florida, Tyson paid attention to mistakes in various films, including The Titanic.
“We know everything about where and when that ship sink,” Tyson said via the discussion posted on YouTube. “[Winset] is looking up and there is only one sky she should have been looking at. The left side of the sky was a mirror of the right side of the sky. It wasn’t only wrong, it was lazy.”
After talking to Cameron about it in person, the director joked: “The last I checked, Titanic worldwide has grossed $1.3 billion. Imagine how much more it would have grossed if I had gotten the sky correct,” Tyson said in the YouTube video from St. Petersburg College.
James Cameron’s Hollywood blockbuster, Titanic, is being re-released in 3D – 15 years after it first hit the big scene. The film’s leading lady, Kate Winslet, has recently revealed that working on the Oscar award winning film was “really, really tough”.
She told the BBC that Cameron was “a very demanding director of his actors and his crew – because he wanted the best”.
Seeing herself up on the big screen as a 21 year-old the British star has admitted she thinks she looks better now than she did before. Although she thinks co-star Leonardo, who became a Hollywood heartthrob thanks to his role as ‘Jack Dawson’ has aged badly.
“We do look very different, we’re older. Leo’s 37, I’m 36 we were 21 and 22 when we made that film. You know, he’s fatter now, I’m thinner,” she told reporters.
The ‘Reader’ actress did confess though as she can’t watch the movie’s sex scenes and thinks that they are ‘terrible’ in 3D. Titanic 3D debuts in theaters in the U.S. on Wednesday, April 4.
