Today marks 25 years since Titanic arrived in theaters and became an instant Hollywood classic, but it also marks 25 years of people arguing about whether both Jack (Leonardo DiCaprio) and Rose (Kate Winslet) could've survived in the end. (And if you've somehow never seen this movie or heard about the ending, then this is your warning for spoilers ahead.)
As fans remember well, Titanic ends with the R.M.S. Titanic...well, plunging into the sea, and as passengers in the ocean are dying of hypothermia, Rose ends up surviving because she lies on a door that is floating in the water. However, Jack does not join her, because when they both try to fit on the door, they keep toppling over (and unfortunately, it leads to his demise).
Ever since this tragic ending, fans have argued that Jack *could've* certainly fit and then they both would've survived. But, the director of Titanic, James Cameron, is coming out to prove that it just actually wasn't possible.
