Documentarian Nathan Grossman Captures a Teenage Icon in “I Am Greta”

Swedish documentarian Nathan Grossman made a leap of faith in 2018 when he decided to film an unknown 15-year-old with a sign staging a one-person strike outside the Stockholm Parliament in order to bring attention to the global climate crisis.

Over the course of 18 months of filming, Greta Thunberg became an international figure and an icon to an increasingly energized youth movement around the world demanding immediate action to address climate change.
