Now In Theaters. Oscar® nominee June Squibb portrays Thelma Post, a feisty 93-year-old grandmother who gets conned by a phone scammer pretending to be her grandson (The White Lotus’ Fred Hechinger). Accompanied by an old friend (Richard Roundtree) and his motorized scooter, she sets out on a wild adventure to reclaim what was taken from her. Inspired by a real-life experience of director Josh Margolin’s own grandmother, THELMA puts a clever spin on movies like MISSION: IMPOSSIBLE, shining the spotlight on an elderly grandmother as an unlikely action hero, with infectious humor throughout. Parker Posey, Clark Gregg, and Malcolm McDowell also star.
