Don’t Say Good Luck is an emotional tour de force in large part because of how personal it is. Hankin wrote the original draft of the script based on her similar real-life story, then Hart and Horowitz collaborated on the rewrite. “It’s based on Laura’s own real-life story of when she got the lead in her high school musical at the same time that her mom’s cancer came back. Because it was so deeply personal and specific, it just feels so real. Even if it’s not exactly their story, people can feel connected to it,” says Hart.
