Movie: Thelma

When 93-year-old Thelma Post gets duped by a phone scammer pretending to be her grandson, she sets out on a treacherous quest across the city 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. June Squibb. PG-13, 97 mins.
