I've seen no better example of how powerful storytelling can be than IF THERE'S A HELL BELOW.

The genius of Williams's film is how it takes this very familiar premise, sets it in near real-time across a visually striking, equally vast and intimate space, then fills it with the kind of existential dread and introspection that lends itself more to an Abbas Kiarostami film.

The first feature by Nathan Williams... makes evocative use of all that vast emptiness, with allusions to existential elements in the style of NORTH BY NORTHWEST and NO COUNTRY FOR OLD MEN.
- The Hollywood Reporter -

Williams does an amazing job of building tension from environment... I can't wait to see what he does next.

It’s that kind of cool, confident filmmaking that makes IF THERE'S A HELL BELOW a highly entertaining shock to the system.
