Actress to star as Harriet Tubman in biopic

'How to Get Away With Murder' star, Viola Davis, will play Harriet Tubaman in an HBO biopic.

The upcoming film is based on Kate Clifford Larson’s book Bound for the Promised Land, the 2003 biographic novel on the Civil War-era abolitionist and prominent Underground Railroad worker.

Viola's character, Harriet, is an activist who came up with a system that allowed slaves to escape to freedom via the Underground Railroad.

To be written by Kirk Ellis, executive producers for movie include Davis, Darryl Frank, Justin Falvey, Doug Ellin, Jim Lefkowitz, Cliff Dorfman, and Julius Tennon.
