Alien Prequel happened on Earth, today

Giger's dreams (nightmares) fuelled his artwork, right? Now, I don't wanna have a painter in the film who opens up a 'parallel dimension' to Gigerworld. No, I want Organised Satanists and Institutionalised Child Stealers and Ludicrous Blood Ritualists to do that job. It takes place now, in our 21st century society of Homage To The Rich, in places like The Shard and Trade Tower One and it's about a parallel world being accessible at the point of these insane and corporatised rituals. Think EYES WIDE SHUT-ish. Think I-ching stargates opening in groups of three three three... So, the portal opens up and we get a glimpse of Gigerworld, all constructed from living UGM or Universal Giger Matter ... and it has a plethora of 'demons' and 'shapeshifters' and 'space jockeys' and such, meddlers with the laws of physics. Humans and Gigerbeasts interact, forming and reforming like oil on water. Gigerworld is exactly the same size as our world and has exactly the same number of xenos of all flavour, seven billion. There must be something about Earth that only allows one-directional flow of energy between the two worlds, from ours to theirs. I don't know, tie it in with the activity of the sun if you want, maybe it's just a question of balance, call the film Tipping Point if you want. Well, our plucky narrator who could be played by Logan Marshall Green 'crosses over' into Gigerworld where we see that hooded Accolytes who have offered themselves up for incorporation in Gigerworld are up to all sorts of no good, kinda Dante's hell-ish, and they're all ending up egg-mogrified. That same someone learns of the Xeno-invasion, maybe from a strong female type played by Noomi Rapace who pursues him sexually, and he concocts a plan of sacrifice by wading into the Gigery maelstrom himself and blending with Gigerworld where he traces the hyperspacer, our Space Jockey, who's been tasked with delivering the eggs to Earth. He stops the Big Invasion of Earth and causes the Alien juggernaut to manifest on LV-426, landing softly in the duststorm. How many eggs were in the original juggernaut? And could there have been a flotilla explosion in Deep Space when the rest of them were killed? Gah, I dunno... Cut back to Space Jockey's chest starting to creak open as our friend LMG emerges ... and then staggers out into a silica storm where he is torn to (literally) bits. THE END.
