Julia Garner is caught in Zach Cregger's twisted trap of a horror film, "Weapons." The "Fantastic Four: First Steps" actress plays an elementary school teacher whose entire class, sans one student, is missing under eerie circumstances.

The first full trailer for "Weapons" may just be one of the more perfect trailers put together in recent memory. The preview gives you the chilling premise of 27 children disappearing in the middle of the night, all from the same class, and a town in panic because of it.

Brolin stars alongside Julia Garner and Alden Ehrenreich in Cregger’s sophomore feature. The cast also includes Benedict Wong, Austin Abrams, Amy Madigan, Cary Christopher and June Diane Raphael. It follows the disappearance of a group of school children in the middle of the night in a small Florida community.
