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. Titanic's Leonardo Dicaprio's chemistry with Kate Winslet's Rose could have melted that fateful iceberg but, the most touching aspect of the film was the very intense love of the main characters. As they fought to survive the ill-fated voyage, Jack and Rose, who had only known each other for a short time, were completely committed to each other.
