Distributor U.S. Release
Ridley Scott returns to the universe he created in ALIEN with Alien: Covenant, the second chapter in a prequel trilogy that began with Prometheus -- and connects directly to Scott’s 1979 seminal work of science fiction. Bound for a remote planet on the far side of the galaxy, the crew of the colony ship Covenant discovers what they think is an uncharted paradise, but is actually a dark, dangerous world -- whose sole inhabitant is the "synthetic" David (Michael Fassbender), survivor of the doomed Prometheus expedition.

The events of the movie would likely take place between Prometheus and the original Alien.
