Don't be fooled by the "East Africa" disclaimer. This is about Nigeria, specifically Lagos at the time of the oil boom, when it was the capital. Although many names have been changed, the Yoruba thunder god, Shango, is not, nor are some of the others.
There was so much humor possible in that time and place (you had to laugh just to keep from crying sometimes) that of course some of it found its way into the film. The author never understood what was happening, so of course he missed a lot, but then he made the very ignorance of the British one of the butts of his humor. God I love British humor, I envy them for it and I'm grateful to them for giving us Chaplin, Bob Hope, and so many others. But I digress. And this film is not on the level of Chaplin or Hope. I was disappointed.
The biggest disappointment was watching great talents like Sean Connery, Diana Rigg and Lou Gossett sleepwalking through their roles on their way to a paycheck. They could have done better.
