Alien 3: Unrequited Vision

Here is a link to a site describing Vincent Ward's concept for Alien3.  Ward had the revolutionary notion of setting the second Alien sequel on a medieval-style monastery satellite made of wood with windmills, wheat fields, and a glassworks, which would have made for some amazing production design.  The plot revolves around the alien creature wreaking havoc among the community of monks who live there who believe it to be a demon of some kind.  The script can be found here.
