What is the underlying opinion on race in the Alien franchise? With the Prometheus/Covenant entries Ridley Scott suggests the story has always been a horror deconstruction of white racist eugenicist theories, specifically targeting the intersectionality between Nazism & white Christianity. This is supported in the thematic work of Dan O'Bannon & HR Geiger, Alien's respective screenwriter and key artistic designer. 

Prometheus details the absurd idea of a white God complex poisoned by his own black genetics and the authoritarian fascist corporation out to profit from the realization/discovery of the "Master Race". Ridley Scott's horror/scifi franchise is destined to be one of the most frightening, intellectually probing and subtle fictional constructs in popular media. Whats most frightening is how many simply buy it at face value as a story about "mankind finding his roots". Scott is playing on the audience's own deeply ingrained racism/authoritarianism and using it against them, to produce scares and ticket sales. Thats one reason he's one of the best directors ever.
