The biopic is based on the biography Bound for the Promised Land: Harriet Tubman, by historian Kate Clifford Larson.

Tubman escaped slavery by fleeing to Philadelphia, and she often returned to the South as an abolitionist escorting hundreds of slaves to freedom in the North via the Underground Railroad. She also worked for the Union Army as a cook and nurse. Tubman soon became the first woman to lead an armed expedition in the war, guiding the Combahee River Raid, which liberated more than 700 slaves in South Carolina.

It’s been reported that another project surrounding slavery, particularly the underground railroad, is said to emerge on NBC’s platform as they wish to expand programming. The tentatively titled “Freedom Run” miniseries will be executive produced by Stevie Wonder and according to Hollywood Reporter is based on Betty DeRamus’ book Forbidden Fruit: Love Stories From the Underground Railroad, which tells the story of the underground railroad through a collection of love stories (many of them fact-based) about men and women, slave and free, black and white, fighting or trying to escape slavery.

“These unforgettable moments in history, which have never been told on television before, are both incredibly painful and heartwarming and need to be presented to the world,” NBC Entertainment president Jennifer Salke told Hollywood Reporter. “We’re honored to be adapting this emotionally affecting book in a television event.”
