Fans love superheroes. We relish origin stories of underdogs who discover their powers and learn to harness them for good. The new film, Harriet, is the story of a real-life hero who does just that. Harriet Tubman didn’t have x-ray vision or telekinetic abilities. She couldn’t fly or freeze time. She didn’t even have a cape. But Tubman did beat the odds, find inner strength, and risk her life to save others over and over again. She was a hero, says the film’s director, Kasi Lemmons, and the biopic, Harriet, is her origin story.
