Knowing the perfectionism for which Cameron is remembered, the respected American astronomer Neil deGrasse Tyson did not accept an error in the position of the stars in Titanic and tried to contact the filmmaker to inform him. "Neil deGrasse Tyson sent me an outrageous email saying that at that time of year and at that point in the Atlantic in 1912, when Rose is lying on a piece of wood staring at the stars, it is not the stars she should be seeing "Said Cameron. The director challenged the astronomer to send him the correct position of the stars at that time, almost 100 years ago. Upon receiving the material, James Cameron did not think twice and rephrased the scene, inserting it into the 3D version.
