Titanic 3d: James Cameron Reshoots Scene After 'Snarky' Email

Titanic director James Cameron has admitted re-shooting a scene in which Kate Winslet's character Rose is seen clinging onto a piece of driftwood in order to survive the ship's sinking. An integral scene in the original film, Cameron says he re-shot the sky for the 3D version after receiving a "snarky" email from an American astronomer.

Leading expert Neil deGrasse Tyson alerted Cameron to the fact that in the Atlantic in April 1912, Rose would not have seen the star field included in the 1997 movie. The director challenged him to send an exact star map which he then included in the 3D relaunch, telling USA Today, "And with my reputation as a perfectionist, I should have known that and I should have put the right star field in.So I said 'All right, send me the right stars for that exact time and I'll put it in the movie". It's the only major technical change to the Oscar-winning drama, which hits cinemas in the UK on Friday (April 6, 2012). Original stars including Kate Winslet and Billy Zane have taken part in an extensive promotional tour in recent weeks, though Leonardo Dicaprio has been unable to attend due to commitments to Quentin Tarantino's new movie Django Unchained.

James Cameron - a filmmaker with numerous blockbusters under his belt - will soon begin work on the Avatar sequel. The first film grossed over $1 billion at the box-office, leading studio bosses to commit to a further two movies.
