The subject of the sumptuously photographed and artfully directed French film Renoir is not immediately apparent from the title. One might expect a biopic about Pierre-Auguste Renoir (Michel Bouquet), a key figure in the French impressionist movement. But the film has almost as much to tell us about Pierre’s son Jean (Vincent Rottiers), a skilled artist in his own right who would go on to become one of the world’s most influential movie directors by creating such critically acclaimed classics as Grand Illusion and The Rules of the Game. No matter. Renoir is less about artists than about the muses who inspire them.
