The elderly couple seen hugging on the bed while water floods their room were the owners of Macy's department store in New York, Ida and Isidor Straus, both of whom died on the Titanic. Ida was offered a seat on a lifeboat but refused so that she could stay with her husband, saying, "As we have lived together, so we shall die together." There was a scene filmed that depicted this moment but was cut from the final version. In this film it is Rose who states "where you go, I go" but it was actually Ida who says this when refusing a lifeboat without her husband.

The bedtime story the Irish mother tells her children is the story of "Oisin and Niamh," a story about a mortal man who falls in love with a goddess and lives with her for 300 years in the land of eternal youth and beauty, Tir Na Nog, before returning home and dying when he steps off his horse. The choice seems particularly apt when considering that though Jack died, his love story was immortalized with Rose, who lived on.
