Soul Power is a 2008 documentary film about the Zaire 74 music festival in Kinshasa which accompanied the Rumble in the Jungle heavyweight boxing championship match between Muhammad Ali and George Foreman in October 1974. The film was made from archival footage; other footage shot at the time focusing on the fight was edited to form the film When We Were Kings.

It's 1974. Muhammad Ali is 32 and thought by many to be past his prime. George Foreman is ten years younger and the heavyweight champion of the world. Promoter Don King wants to make a name for himself and offers both fighters five million dollars apiece to fight one another, and when they accept, King has only to come up with the money. He finds a willing backer in Mobutu Sese Suko, the dictator of Zaire, and the "Rumble in the Jungle" is set, including a musical festival featuring some of America's top black performers, like James Brown and B.B. King.
