The film, directed and co-written by Gary Ross ("Seabiscuit," "The Hunger Games"), tells the little-known story of Newton Knight, a soldier who deserted the Confederate army and then led an insurrection against it. With a makeshift band of escaped slaves and disgruntled farmers, Knight held several counties in Mississippi to create his own free state, based on the idea that "every man is a man" and that "no man ought to stay poor so another man can get rich." A fine and absorbing film, it's also an expression of our era in that it blends two strains in our current political discourse, multiculturalism and angry populism. [...] soon Knight's effort to escape the hangman throws him right into the company of escaped slaves who live in a swamp where the army can't bring its horses. Yet the perspective remains true to the era, meaning people's teeth are dingy, clothes are old and the women don't wear makeup. Even as it looks back, "Free State of Jones" also peers toward the promise of a new America, as when Knight and his second wife, Rachel - a former slave played with alert sensitivity by Gugu Mbatha-Raw - look at their newborn child.
