In order to make people in the water appear frozen, the makeup team used a powder on the actors’ faces, which then crystallized when exposed to water
Nothing’s sadder than the end of Titanic, where we don’t just see Rose have to let Jack go but also bear witness to all the death that the ship’s sinking caused. All the bodies in the water of those who have frozen to death (along with Kate Winslet’s barely alive Rose) seriously look as if they are human icicles. Apparently, the makeup team for Titanic was able to create this amazing effect by using a specific powder on the actors’ faces. This powder would crystallize when exposed to water – thus giving those who met their end in the unbearably cold Atlantic Ocean their frost-covered exteriors.
