It's hardly a cult. The plot you're describing has been known for a while, and we even have a movie about it: AvP. My only complaint about it is it presented aliens as dumb reptiles, despite a much bigger brain. Another movie - the Ascent of Jupiter - has explored this idea further. One of the scenes there is a brief glimpse into the civilization of reptiles on Jupiter: a flat hellish world with thick orange clouds instead of skies and a high tech brutalistic scenery.
