Actor Billy Zane, who essayed the role of Cal Hockley in "Titanic", says Leonardo DiCaprio's character Jack had to die in the blockbuster film. The James Cameron 1997 directorial has caused debates over the years over the fact that Jack perished in the icy water while actress Kate Winslet's character Rose DeWitt Bukater stayed safe on a floating wooden door at the end of the movie.
