Director James Cameron says he has conducted a scientific study , finally proving that ( SPOILER ALERT ) Jack had to overwhelm at the goal of the movieTitanic .

In the movie , protagonists Jack and Rose combat against the betting odds to last as the titularTitanicsinks into the Atlantic Ocean . Having fought off an angry fiancé , escaped from an underwater batting cage , and clinging to the hull as it pass , the two find that they are defeated by one last hurdle : there is n’t enough distance on a door .

As the two cling to a while of detritus to save themselves from overwhelm and hypothermia in the dusty sea , Jack realize that the only direction for Rose to survive is if he perish in the H2O and allows her to swim on the door . He does so , and die while she live .

Over the years , people have hypothesize that there was , in fact , plenty of room for both of them if Rose were just to shunt up a routine . The subject was even a subject of aMythbustersepisode , where the team conclude that the two could have float long enough to be rescued if they had just tied the liveliness crown to the bottom of the door .

" However baronial Jack ’s intentions might have been , sometimes discretion is the better part of valiancy , " theMythbusters tot up . " With all we ’ve learned , I think Jack ’s death was needless . "

Kate Winslet , who played Rose , also went on record in 2016,telling Jimmy Kimmel"I think he could have actually fit on that bit of room access " .

However , James Cameron has n’t forget it at that . As well as making it clear that " Jack had to die " as the floor was about sacrifice , the director now says that he and a squad have conducted a scientific psychoanalysis of the door situation .

“ We have done a scientific study to put this whole affair to rest and repulse a interest through its heart once and for all,”Cameron told Postmedia , adding that they had done a forensic analysis with a hypothermia expert , for a piece that will be aired in February .

" We took two stunt mass who were the same organic structure mass of Kate and Leo and we put detector all over them and inside them and we put them in ice H2O and we quiz to see whether they could have survived through a variety of methods and the reply was , there was no means they both could have survived , " he differentiate the wall socket . " Only one could survive . ”
