Dark of the Sun (1968)

A band of mercenaries, led by Rod Taylor and his friend Jim Brown, are hired by Congolese President Calvin Lockhart to ostensibly rescue Europeans from an isolated mining town, but in actuality to recover $50 million worth of diamonds from the town’s vault. It may or may not be an accurate portrayal of political struggles in the heart of Africa post-colonialization, but it certainly is a violent one, including scenes of children being murdered, rape, and an iconic chainsaw battle. There is only the slightest pretense that the mission isn’t completely about war profiteering nor much concern about the growing body count toward its completion.
