I've to read Aliens: Sacrifice
and yeah, the idea is interesting by itself. One can speak of madness, but I can imagine some people being victims of manipulation by an insane ... as in real life cults. It would be great if a director explores the psychological side of worshiping a monster. Why would people do that?
MotivationsMaybe they admire the purity of the survivor; unclouded by conscience, remorse, or delusions of morality. So from that way of thinking, they start to interpret the Alien as a superior being or something.
Another scenario is that humans in a lost space society can no longer reproduce by sex and want to develop a life cycle similar to that of the Alien. That or maybe some kind of phallocentric cult, who see in the Perfect Organism a symbol of fertility through life and death.
Of course we can't forget the old cliche of theistic satanism, with the Alien being interpreted by crazy folks as the antichrist or the Devil.
Settings1) Bladerunneresque: The Alien being worshiped by an erotic / kinky religion, with dudes that looks like the Cenobites from Hellraiser, in a cyberpunk setting.
Note: I'd be enthusiastic about a setting more or less similar to Vincent Ward's Alien³ or Scott Sigler's Alien - Phalanx: humans living with an age-old lifestyle despite being the future. So:
2) Vintage: I can portray in my head a colony on another planet where people live like humanity in the 17th century, all of them being organized by something like a space Puritan doctrine.
3) Ancient: On the other hand, there is the possibility of reusing the concept of Dan O'Bannon for third time (AVP & Prometheus). At AVP we have a small glimpse of the idea of sacrifices involving Aliens at a temple, but only for a brief flashback, and in Prometheus we don't have anything of that at all. The religious aproach is handled in a different way. I want to see the sacrifices (and why not, the torture too) being experienced by the characters thenselfs. So I was thinking of humans from the future building ancient-looking temples similar to Earth's pyramids, where Aliens are worshiped and terrifying rituals take place.
4) Medieval & Gothic: I still dig the medieval setting, which can be enhanced with gothic elements to build an even more unsettling atmosphere. That being said, I believe
Eggmorphing would be neat for this.
