The documentary, produced by Chew On It Productions in partnership with education charity Worldwrite, has its premiere in London on 26 March.
It focuses on a town called Ajumako-Bisease in Ghana, which made Sir Bob Geldof its chief of development in 2004. The ceremony was filmed for the BBC's Geldof in Africa series in 2005.
The people of the town criticise Geldof for failing to return since his coronation. Viv Regan, producer of the series, said: "The people of Ajumako-Bisease asked Geldof to be their chief of development, but they are still waiting for him to deliver."
A spokesman for Geldof declined to comment.
