Last year, Brian Duffield’s No One Will Save You told a fully developed alien invasion story with a single line of dialogue. In 2013, J.C. Chandor created a breathless, satisfying adventure yarn without one word with All Is Lost.

A little more than midway through the post-apocalyptic horror Azrael, director E. L. Katz (working from a script by Simon Barrett) introduces the first speaking character. It’s a cagey move, and one that solidifies the filmmakers’ ability to clarify not just an immediate situation but an entire mythology without a single comprehensible syllable spoken.

Our signposts are three separate cryptic prophesies scrawled across the screen. Other than that, we witness a world left behind. Our tale is set many years after the Rapture. Alone in a woods, one woman (Samara Weaving, Ready or Not) finds beauty in nature. As she brings a gift to her lover (Nathan Stewart-Jarrett, Femme), they recognize a bird call and flee.

Because that was definitely not a bird.

Anyone who’s followed Weaving’s career knows she’s up for some relentless, bloody action. She has her fill of it here, battling a left-behind cult as well as bloody thirsty, flesh bound demons. She’s so expressive that the character never feels limited without lines.

The balance of the ensemble is also up to the task at hand—Katariina Unt and Eero Milonoff (of the amazing Border) leave a particular impression.

So do the demons, which come across like char broiled crawlers from The Descent. Nice!

Katz hit out-the-gate with his feature debut, Cheap Thrills. Barrett has been hit or miss, but his hits have soared, You’re Next and The Guest among them. What they fully understand is how to develop tension, how to direct your attention, and how to use the camera to tell attentive audiences all they need to know.

There’s nuance and depth for those who invest, but at 85 minutes and boasting almost constant action and bloodshed, Azrael is a solid choice for even those with a limited attention span.
