The scene in which Rose meets Jack to thank him for saving her life was improvised by the two actors at James Cameron’s request, and the spitting scene was almost all ad-lib. Cameron also credits Kate Winslet with writing the heart-wrenching “This is where we first met” line during the final sinking, as well as suggesting Rose spit in Cal’s face rather than (as scripted) jab him with a hairpin.
