Factual error: When in the cooking pot, corn, bell peppers, and bananas are all visible. None are native to Africa.
Factual error: The movie takes place during or shortly before World War I. At one point, Quatermain and Jessie find a German base. Thus, they are probably in one of the pre-World War I German African colonies (Probably German East Africa or German South West Africa). There is a red, white, and blue French flag flying over the camp instead of a German flag.
Factual error: Quatermain and Jessie are on the roof of the caboose of the train. The train engineer slams on the brakes because there are elephants on the tracks. Instead of being flung forward as the train slows, Jessie is flung towards the rear.
