It's an essay by an angry Kenyan author Bivanyanga that is quite humorous.
A few passages: Always use the word ‘Africa’ or ‘Darkness’ or ‘Safari’ in your title. Subtitles may include the words ‘Zanzibar’, ‘Masai’, ‘Zulu’, ‘Zambezi’, ‘Congo’, ‘Nile’, ‘Big’, ‘Sky’, ‘Shadow’, ‘Drum’, ‘Sun’ or ‘Bygone’. Also useful are words such as ‘Guerrillas’, ‘Timeless’, ‘Primordial’ and ‘Tribal’. Note that ‘People’ means Africans who are not black, while ‘The People’ means black Africans.
In your text, treat Africa as if it were one country. It is hot and dusty with rolling grasslands and huge herds of animals and tall, thin people who are starving. Or it is hot and steamy with very short people who eat primates. Don’t get bogged down with precise descriptions. Africa is big: fifty-four countries, 900 million people who are too busy starving and dying and warring and emigrating to read your book. The continent is full of deserts, jungles, highlands, savannahs and many other things, but your reader doesn’t care about all that, so keep your descriptions romantic and evocative and unparticular.
Your African characters may include naked warriors, loyal servants, diviners and seers, ancient wise men living in hermitic splendour. Or corrupt politicians, inept polygamous travel-guides, and prostitutes you have slept with. The Loyal Servant always behaves like a seven-year-old and needs a firm hand; he is scared of snakes, good with children, and always involving you in his complex domestic dramas. The Ancient Wise Man always comes from a noble tribe (not the money-grubbing tribes like the Gikuyu, the Igbo or the Shona). He has rheumy eyes and is close to the Earth. The Modern African is a fat man who steals and works in the visa office, refusing to give work permits to qualified Westerners who really care about Africa. He is an enemy of development, always using his government job to make it difficult for pragmatic and good-hearted expats to set up NGOs or Legal Conservation Areas.
Describe, in detail, naked breasts (young, old, conservative, recently raped, big, small) or mutilated genitals, or enhanced genitals. Or any kind of genitals. And dead bodies. Or, better, naked dead bodies. And especially rotting naked dead bodies. Remember, any work you submit in which people look filthy and miserable will be referred to as the ‘real Africa’, and you want that on your dust jacket. Do not feel queasy about this: you are trying to help them to get aid from the West. The biggest taboo in writing about Africa is to describe or show dead or suffering white people. Animals, on the other hand, must be treated as well rounded, complex characters. They speak (or grunt while tossing their manes proudly) and have names, ambitions and desires. They also have family values: see how lions teach their children? Elephants are caring, and are good feminists or dignified patriarchs. So are gorillas. Never, ever say anything negative about an elephant or a gorilla. Elephants may attack people’s property, destroy their crops, and even kill them. Always take the side of the elephant. Big cats have public-school accents. Hyenas are fair game and have vaguely Middle Eastern accents. Any short Africans who live in the jungle or desert may be portrayed with good humour (unless they are in conflict with an elephant or chimpanzee or gorilla, in which case they are pure evil).
It's quite a relevant essay. Oh how I wish there was a "How to make a movie with an African scene" then it would help movie makers greatly too.
