James Cameron's Titanic film has been praised for bringing one of the most harrowing events to life on the big screen. Sure, the based-on-real-events film is focused on some fictionalized characters - the love triangle of Rose, Jack, and Cal were not a part of the luxury cruise ship's maiden voyage - but there are so many characters modeled after actual passengers on board the Titanic.
Nearly all of the rest of the characters in the movie were based on real people, in fact. Again, while their stories may be slightly exaggerated, it's necessary to look back on them as people who experienced this tragedy first-hand. And for the most part, the casting truly hit the nail on the head with a lot of those who took up these roles. It's as if some of these passengers were time travelers, even.
