Ridley Scott is back with the official trailer for the looming terror that is Alien: Covenant. He's said to be returning the franchise to its horror roots, which makes sense because the thought of extraterrestrials just got a little scarier following the unveil of Trappist-1.

The film hits theatres on May 19 and stars Katherine Waterston, Danny McBride and Carmen Ejogo as they come across a fallen spaceship from Prometheus.
