The creative goal of “Chevalier” is to provide some illumination on the achievements of classical composer Joseph Bologne, Chevalier de Saint-Georges. He was a man of extreme talent and confidence, but he was the child of a white aristocrat and a black slave, ushered into a world that had little interest in a public celebration of his achievements. Screenwriter Stefani Robinson and director Stephen Williams don’t deliver a traditional bio-pic with “Chevalier,” instead looking to dissect a short amount of time in his life, where the pressures of conformity collided with the development of rebellion in France. There’s combustible energy in the endeavor, which gets off on the right foot, focusing on racial and social challenges for the main character, highlighting his coping mechanisms while facing constant dismissal. It’s not a cinematic spark that remains for the entire run time, but it’s there to get the picture going, generating interest in the ways of a virtuoso and his battle to be treated humanely.
