In “The American Society of Magical Negroes,” the writer-director Kobi Libii’s debut feature film opening March 15, a mysterious group of Black people possess superpowers. But unlike Black Panther or Miles Morales’s Spider-Man, this group doesn’t fight criminals or take on villains.

Instead, the members of this society wield their powers only for a very specific purpose: soothing the anxieties of white people.

Endowed with the ability to perceive white people’s frustrations — represented by a floating dial that measures “white tears” — the members spend their days making lost purses reappear, transforming bland outfits into hip ones and doing whatever else white people require to be happy.

This conceit satirizes the cultural trope of the Magical Negro, in which Black characters in a plot exist solely to aid the white protagonists. By incarnating this trope in the form of a secret society set in present-day America, the film critiques the ways in which Black people continue to be forced into deference toward white people.

“I was sat down quite explicitly by older Black people in my life and told how to act around the police, that I needed to be polite there and that’s what I needed to do to stay alive,” Libii said in an interview.

“And I personally believe I overlearned that lesson,” he added.
