Move over, Ari, here comes Harriet. Doug Ellin is switching gears in a big way with his next HBO project. The Entourage creator will now be executive producing a Harriet Tubman biopic with Viola Davis. Ellin says of the 2003 Tubman biography, Bound for the Promised Land, “My childhood friend Cliff Dorfman gave me Kate Clifford Larson’s book.” Ellin became fascinated and thought Davis was “the perfect choice” to play Tubman. In an interview, the creator of Entourage said, “We set up a lunch and gave her the book. She loved it as well. It’s a personal passion for me because Harriet was so much more than just the Underground Railroad that most associate her with.”
