Two decades after the Titanic blew up the big screen, director James Cameron is still defending the plot points on Hollywood’s second-most-profitable movie in history. Jack had to die, Cameron argues, for the film to mean anything. “I think it’s all kind of silly, really, that we’re having this discussion 20 years later. But it does show that the film was effective in making Jack so endearing to the audience that it hurts them to see him die. Had he lived, the ending of the film would have been meaningless,” he tells Vanity Fair. Titanic will begin a one-week run in select AMC theaters on December 1st to celebrate it's 20th anniversary.
