The Oscar-winning director has revealed that when his blockbuster was originally released, an astronomer wrote to him to tell him he got the stars wrong at the end.
According to Gawker.com, when Rose looks up at the sky from her position on the raft, it's the wrong star field she's gazing at.
No other changes were made during the film's adaptation for 3D, due for release this week, although the stars themselves have.
Kate Winslet has revealed she now cringes when she watches the love scenes between her and Leonardo DiCaprio, that the famous theme song by Celine Dion makes her want to throw up, and that she's a lot thinner than she used to be, while her co-star DiCaprio is the opposite.
