Titanic director James Cameron has chosen to re-shoot the iconic scene where Rose (Kate Winslet) tells Jack (Leonardo DiCaprio) to “never let go” as she floats on a piece of wood in the freezing Atlantic Ocean. African-American astronomer Neil deGrasse sent a “quite snarky” e-mail to Cameron, informing him that the stars’ positions in the clear sky on the morning of April 15, 1912 at 4:20am, were not accurately pictured in the film. The Telegraph reports on the story:

Cameron, a famed perfectionist, has admitted re-doing a scene in which character Rose clings to a piece of driftwood to survive after leading expert Neil deGrasse Tyson sent him a “snarky” email.

The American astronomer accused the original film of having the wrong star field for the time and date, 4.20am on April 15, 1912, and claimed Cameron should have known better.

In response, Cameron challenged him to send the exact star map and has now included it in the relaunched 3D version of the blockbuster film.
