Christopher Vourlias What’s in a name? For the Congolese Belgian rapper-turned-filmmaker Baloji, whose directorial debut, “Omen,” bows in the Cannes Film Festival’s Un Certain Regard section on May 22, it’s a question that poses itself whenever flustered immigration officials inspect his passport at the airport in Congo. “Always the same question, every time,” Baloji tells Variety. “Do you know what it means?” In the pre-colonial era, baloji meant “man of science” in Swahili, but the word became corrupted by Christian evangelists during the years of Belgian colonial rule. Today it is more akin to a man of occult sciences and sorcery. “Some people of faith do not dare to say my name in public for fear of invoking evil spirits and the suspicions that may accompany it,” the director says. “In such an animistic culture it is equivalent to being called devil or demon in the West.”
