‘Alien: Covenant’ clips are the stuff nightmares are made of

Ridley Scott knows how to scare us. He’s been doing it for over 40 years.

But the new footage from his upcoming Alien: Covenant that premiered Thursday at CinemaCon makes that alien bursting out of John Hurt’s chest look tame in comparison.

Scott wasn’t in attendance at the annual gathering of theatre owners and exhibitors but gleefully teased its terrors.

The hyperviolent sequences show new nightmares for the crew of the colony ship Covenant, with blood, shrieks and creatures emerging out of human backs and mouths.

There’s also a bloody shower scene that could give Psycho a run for its money.
