There are also more subtle nods towards filmmaking conventions, that prove Insaan is not only an accomplished actor, director and prop maker, but also a keen student of the art. For instance, the villains, those with evil in their hearts, are shown to be with black faces. As they are brainwashed by Insaan, the black leaves their faces. They start looking more — shockingly enough — human. Then, in a clear sign that the film, despite its lofty accomplishments, remains rooted in quotidian realities of small-town India, these faces turn whiter as their hearts get purer.
