Coogler played football in high school, and between his fitness and his humble listening poses — leaning forward, elbows propped on knees — he reminds me of what might happen if a mild-mannered athlete accidentally discovered a radioactive movie camera and was gifted with remarkable artistic vision. He’s interested in questions of identity: What does it mean to be a black person or an African person? “You know, you got to have the race conversation,” he told me, describing how his parents prepared him for the world. “And you can’t have that without having the slavery conversation. And with the slavery conversation comes a question of, O.K., so what about before that? And then when you ask that question, they got to tell you about a place that nine times out of 10 they’ve never been before. So you end up hearing about Africa, but it’s a skewed version of it. It’s not a tactile version.”

Around the time he was wrapping up “Creed,” Coogler made his first journey to the continent, visiting Kenya, South Africa and the Kingdom of Lesotho, a tiny nation in the center of the South African landmass. Tucked high amid rough mountains, Lesotho was spared much of the colonization of its neighbors, and Coogler based much of his concept of Wakanda on it. While he was there, he told me, he was being shown around by an older woman who said she’d been a lover of the South African pop star Brenda Fassie. Riding along the hills with this woman, Coogler was told that they would need to visit an even older woman in order to drop off some watermelon. During their journey, they would stop occasionally to approach a shepherd and give him a piece of watermelon; each time the shepherd would gingerly take the piece, wrap it in cloth and tuck it away as though it were a religious totem. Time passed. Another bit of travel, another shepherd, another gift of watermelon. Eventually Coogler grew frustrated: “Why are we stopping so much?” he asked. “Watermelon is sacred,” he was told. “It hydrates, it nourishes and its seeds are used for offerings.” When they arrived at the old woman’s home, it turned out that she was, in fact, a watermelon farmer, but her crop had not yet ripened — she needed a delivery to help her last the next few weeks.

When I was a kid, I refused to eat watermelon in front of white people. To this day, the word itself makes me uncomfortable. Coogler told me that in high school he and his black football teammates used to have the same rule: Never eat watermelon in front of white teammates. Centuries of demonizing and ridiculing blackness have, in effect, forced black people to abandon what was once sacred. When we spoke of Africa and black Americans’ attempts to reconnect with what we’re told is our lost home, I admitted that I sometimes wondered if we could ever fully be part of what was left behind. He dipped his head, fell briefly quiet and then looked back at me with a solemn expression. “I think we can,” he said. “It’s no question. It’s almost as if we’ve been brainwashed into thinking that we can’t have that connection.”

“Black Panther” is a Hollywood movie, and Wakanda is a fictional nation. But coming when they do, from a director like Coogler, they must also function as a place for multiple generations of black Americans to store some of our most deeply held aspirations. We have for centuries sought to either find or create a promised land where we would be untroubled by the criminal horrors of our American existence. From Paul Cuffee’s attempts in 1811 to repatriate blacks to Sierra Leone and Marcus Garvey’s back-to-Africa Black Star shipping line to the Afrocentric movements of the ’60s and ’70s, black people have populated the Africa of our imagination with our most yearning attempts at self-realization. In my earliest memories, the Africa of my family was a warm fever dream, seen on the record covers I stared at alone, the sun setting over glowing, haloed Afros, the smell of incense and oils at the homes of my father’s friends — a beauty so pure as to make the world outside, one of car commercials and blond sitcom families, feel empty and perverse in comparison. As I grew into adolescence, I began to see these romantic visions as just another irrelevant habit of the older folks, like a folk remedy or a warning to wear a jacket on a breezy day. But by then my generation was building its own African dreamscape, populated by KRS-One, Public Enemy and Poor Righteous Teachers; we were indoctrinating ourselves into a prideful militancy about our worth. By the end of the century, “Black Star” was not just the name of Garvey’s shipping line but also one of the greatest hip-hop albums ever made.
