'Don't Say Good Luck' cast guide: the singers and the schemers
Netflix’s Don’t Say Good Luck assembles a quietly stacked cast—fronted by the young star leading the Waitress production—with acclaimed faces playing her family, teachers, and friends.
The heart of the movie is a school staging of Waitress, where theater kid Sophie Birenbaum lands the lead just as her family is hit with a devastating turn: her mom’s cancer comes back. The big musical moments are there, but the toughest scenes happen offstage as Sophie tries to keep up with rehearsals, friends, and school while her home life changes fast.
Led by Sunny Sandler as Sophie, the film mixes a teen ensemble with heavy-hitting adults. Director Julia Hart has praised Sandler’s singing, emotional range, and her ease shifting between buoyant numbers and the story’s heavier beats, setting up a performance that has to carry both the show-within-a-show and a family in crisis on Netflix .
Who’s who
- Sunny Sandler — Sophie Birenbaum, a theater-obsessed teen who nabs the lead in her high school’s Waitress and tries to hold it together as real life intrudes.
- Melanie Lynskey — Elizabeth Birenbaum, Sophie’s mom, whose cancer returns, reshaping what should’ve been a celebratory time.
- Max Greenfield — Ted, Sophie’s dad, a steady presence as the family navigates a scary stretch together.
- Stephanie Beatriz — Ms. Parker, a pivotal adult in Sophie’s school theater world, helping guide the student production.
- Bebe Neuwirth — Linda, Sophie’s grandmother, bringing serious stage-and-screen pedigree to the family mix.
- Steve Buscemi — Dale, Sophie’s grandfather, in a role the actor has described as his first time playing a grandpa.
- Jack Champion — Jack, part of Sophie’s school circle and the younger ensemble around the production.
- Scarlett Estevez — Carolyn Morales, another key student in Sophie’s high school orbit.
- Emma McNulty — Erin, one of the theater kids in Sophie’s company.
- Elyse Bell — Mallory Sinclair, adding to the backstage dynamics among the students.
- Jon Lovitz — Lenny, a supporting role that folds extra comedy into the family-and-school blend.
Steve Buscemi says it’s his first time playing a grandfather on screen.
There’s a broader bench of players filling out the halls and the Birenbaum home, including Ethan Costanilla as TJ, Ade Chike Torbert as Frank, and Dylan Pitanza as Alan Fishman, plus additional family members, younger Birenbaum siblings, and the high school ensemble that powers the musical numbers.
Beyond the onstage rush, the story leans into growing up under pressure—loss, resilience, and learning to hold on to the present—while Ms. Parker and Sophie’s classmates keep the curtain rising on their show no matter what’s happening at home.
