Watch: Sandra Bullock fights through another horrifying trailer for the apocalyptic thriller ‘Bird Box’

Never take off your blindfold.

The newest trailer for Netflix’s upcoming apocalyptic thriller Bird Box has just arrived.

The film, based on the 2014 novel by Josh Malerman, will follow Sandra Bullock as she navigates through an eerie world where an ominous, unseen force drives society to suicide. If you look at the “creatures,” they’ll show the victim their worst fears and drive them to insanity. To survive, people have to wear blindfolds so the other-worldly entities can’t possess them.

Watch the trailer for Bird Box below.

The film comes out on December 21st on Netflix, and it will also star John Malkovich, Sarah Paulson and Moonlight actor Trevante Rhodes.
