LAGOS, Nigeria (AP) --

The film stars an Oscar nominee, is set in Nigeria during a civil war, is based on an award-winning novel and the head of Nigeria's censorship board reportedly loved it. Yet a week after the scheduled premiere of "Half of a Yellow Sun," it still has not been shown in any theater in Nigeria.

Many commentators on social media believe that the censors are afraid that tribal rivalries could be inflamed if the movie is shown in theaters across Africa's most populous nation.

Nigerian government censors are effectively banning the film but they will not say why, the film's director, Biyi Bandele, told The Associated Press on Thursday. He spoke in a telephone interview from his home in London, where the movie placed among the 10 most popular at cinemas over the Easter weekend. It debuts in the U.S. on May 16.

The movie stars Oscar nominee Chiwetel Ejiofor ("12 Years a Slave" – the 2014 best picture Oscar) and Thandie Newton and is an adaptation of the book by Chimamanda Ngozi Adichie. It is partly set during the 1967-1970 civil war when the southeast sought to break away from the federation, and it comes at a time when Nigeria is threatened by an Islamic uprising in the northeast, jeopardizing unity between the mainly Muslim north and predominantly Christian south.

"More than 40 years after the end of the war, the problems that caused the war are even more pronounced," Bandele said. "I'm convinced that an organization like Boko Haram (Islamic extremists) would not exist today if we had dealt with the root causes of the war."

A ban on the movie would perpetuate the conspiracy of silence that has kept Nigerians from discussing the civil war, a subject that was pointedly excluded from history lessons in schools, Bandele said.

The National Film and Video Censor Board insisted it has not banned the movie but delayed its registration over "some unresolved issues which have to be sorted out."

The movie's Nigeria premiere was set for April 25. Invitations had been sent out and the film was to play in most theaters in the country. The previous day, the board told the distributors that the film had not yet passed the registration process.

About 1 million people died in the war for an independent Biafra for the Igbo people of the southeast, mainly Igbos who starved to death because food imports were blocked. Then, leaders of the Igbo, who are almost exclusively Christians, accused the federal government of failing to protect them as Muslims from the Hausa tribe in the north slaughtered about 30,000 of them.

The tribal tensions and mistrust that led to that war remain strong. Today, some northern leaders accuse the federal government, led by a Christian southerner, of orchestrating mass killings of Muslims by soldiers in the northeast. There are also conflicts over land and resources across the central part of the country that pit mainly Muslim Fulani herders against predominantly Christian farmers from other tribes.

Several members of the censorship board, including its director general Patricia Bala, viewed the film at its premiere at the Toronto Film Festival in September. "She saw the movie and told us afterward how much she loved it and why (such) movies should be encouraged … She was very encouraging, very positive and did not at any time express any reservations about the film," Bandele said.

The board's website may offer a clue as to why it hasn't authorized release of the film. The board's mission includes ensuring that "objectionable materials capable of inciting civil strife is reduced or eliminated completely" and banning material that would "encourage racial, religious or ethnic discrimination or conflict."

Bandele calls the film "a very, very faithful" adaptation of the novel, and says it is not a war flick. The book has been read by millions of Nigerians since its release in 2006, he said. Many more millions of illiterate Nigerians would be able to appreciate it through the movie.

"This movie is a sort of love story, a love letter to Nigeria's very complex and complicated history, and it was meant to be a cautionary tale to say we can disagree as much as we want but war is never the answer," he said.

There has still been no word on when the movie might be shown here, if at all.
