Deadline has learned of a Harriet Tubman feature film that is in the early stages of pre-production. 

The biopic about the abolitionist, titled Harriet, is being put together by Charles D. King, Macro CEO and producer, and Seith Mann, director of the TV show Homeland. Production is slated to begin early next year. The script was written by Gregory Allen Howard, who wrote Remember the Titans and Ali.

Tubman’s life follows many conventions of a dramatic narrative: her birth into slavery, escape, and help of others along the Underground Railroad is a heroic story. Previously, she has been depicted in the TV miniseries A Woman Called Moses in 1978 and HBO is apparently working on a project on Tubman, that was predicted to feature actress Viola Davis.
