Sunny Sandler

Don’t Say Good Luck isn’t astute and thoughtful solely because it features Melanie Lynskey. That the Yellowjackets star was the only actor that filmmaker Julia Hart wanted (and even considered) for the movie’s second-biggest role is a perfect piece of shorthand, however. How do you instantly signal to the watching world that a film values emotional honesty, and that it isn’t afraid to confront life’s heartaches and struggles with authenticity? How do you convey that a movie that plays with plenty of familiar elements — such as telling a teen coming-of-age tale, and one about staging a musical at that, while unfurling an illness story — won’t settle for standard? You Are So Not Invited to My Bat Mitzvah’s Sunny Sandler is Don’t Say Good Luck’s lead, but Lynskey is its lighthouse.
