Not that we would ever want to be on a sinking ship, but if we had to be, Jack Dawson would certainly be a welcome first mate. If only Leonardo Dicaprio's chemistry with Kate Winslet's Rose could have melted that fateful iceberg -- indeed, the most touching aspect of James Cameron's 1997 blockbuster about the historic maritime tragedy was the intense love between Rose and Jack. As panic set in all around them on the ill-fated voyage, the lovers were completely committed to each other's survival. And the only thing that could tear them apart was Jack's untimely death. We all left the theater in tears, but just as certain as Rose that she'd be reunited with her true love someday.
