DIRECTOR James Cameron was forced to reshoot part of his Titanic 3D film after an astronomer complained the stars were in the wrong place as the ship sank.

Cameron, a notorious perfectionist, has admitted re-doing a scene in which character Rose lies on a piece of driftwood 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.          –TG
