The person who would bankroll a Harriet Tubman biopic would likely be someone who was particularly touched by her story. Such a person would not have to be black, but I don’t know how you separate the paucity of black people with the power to green-light from the paucity of good films concerning black people in American history.
Moreover, movie-making is risky and expensive. Any discussion of the lack of a Harriet Tubman biopic should begin with the shameful fact that median white wealth in this country stands at $110,000 and median black wealth stands at around $5,000. It would be nice to think that this gap reflected choices cultural and otherwise, instead of the fact that for most this country’s history its governing policy was to produce failure in black communities, and most of its citizens supported such policies. It would be nice if Hollywood were more moral and forward-thinking than its consumer base. But I would not wait around for such a day."
