"We cannot hide from our history," she wrote in The New Yorker last week. "Many of Nigeria's present problems are, arguably, consequences of an ahistorical culture."
Bandele said a ban on the movie in Nigeria would not only perpetuate the culture of silence that has kept Nigerians from discussing the war but also hurt the growth of the film industry.
"It seemed, until this ban, a harbinger of things to come," he told ABC News about "Yellow Sun. "What the censorship board is effectively doing is driving a stake through the heart of the film industry."
Despite the politics surrounding the film, Adichie stressed in "The New Yorker" that the film's "real triumph is not in its politics but in its art," with Ejiofor and Newton giving the "most complex performances of their careers."
"The headlines sometimes take the humanity, the individual out of history," he said about the latest stories coming from Nigeria. "Art personalizes it. I hope that someone who goes and sees my film will see that yes, it's a dysfunctional society, but people thrive there as well. They fall in love, fall out of love, do foolish things and nice things, and are just like people everywhere."
