I personally love Alien3 and don't want a movie to retcon it, but that's another debate that's been discussed to death.
What I'm concerned about is this picture:
This gives me the impression that the company would finally get a hold of the aliens and successfully weaponize them. Surely, they'd break out at some point and wreak havoc, but still. The idea of the aliens ever being tamed in the first place doesn't sit well with me.EDIT: My bad. This one wasn't done by Neill.
Then there's this:
Is that some kind of disguise? That reminds me of:
The idea of being able to fool an alien with a disguise doesn't sit well with me either. But his notes say it's a space jockey pilot suit? Would this movie have conflicted with Prometheus and establish a different history between the engineers/jockeys and the aliens? Why would their space helmets resemble alien heads? Wiping out 3 and Resurrection is bad enough. It would be really irritating if this contradicted Scott's prequels too. I hate it when franchises get muddy with alternate continuities, (like Halloween and Texas Chainsaw).
It's also possible that some of these were just fun doodles for him and they weren't really going to play into the script.
If this movie never happens, I really hope he at least releases his treatment so we can have an idea of what the story would have been. Perhaps he could give it to Dark Horse for a comic book adaptation.
