This 2016 movie is about the early years of the space race, when scientists were still figuring things out – and so were mathematicians, some of whom get special attention in this inspirational character study. What makes them so special? For one thing, they’re women. For another, they’re African-American. In the period in which this movie is set, both of those factors are significant, and unusual. Taraji P. Henson, Octavia Spencer, Janelle Monae star.
