Steven Williams and Stefani Robinson's Chevalier (Searchlight, 4.7.23) is a rare historical drama that doesn't, for a change, smack of presentism. It's the real-deal saga of a gifted young mulatto fellow from Guadalupe (Kelvin Harrison's Joseph Bologne, aka Chevalier de Saint-Georges) vs. evil snooty racist whiteys of Paris and Versailles.
