The Tunnel (2019) 

You know that primal dread when the lights flicker and the air turns thick? The Tunnel bottles it and shakes hard.
Norwegian director Pål Øie drops you straight into hell’s own service tunnel: a snow-choked mountain pass in the middle of nowhere, flames roaring, alarms screaming, and one stubborn journalist (Thorbjørn Harr, raw and relentless) clawing through smoke to rescue survivors. What starts as a routine fire story spirals into a suffocating nightmare when he discovers the tunnel was never meant to be opened again.
Shot almost entirely in claustrophobic real locations, every drip of water, every groan of collapsing concrete hits like a fist. The camera presses so close you taste the soot; when the walls start bleeding secrets (abandoned experiments, bodies bricked up decades ago), the horror goes from physical to psychological in one heartbeat. No jump-scare crutches here, just slow-burn terror that coils tighter with every blocked exit.
It’s 28 Days Later meets The Descent, but colder, meaner, and smarter. By the time the final truth crawls out of the dark, you’ll need fresh air and therapy.
Underrated gem that punches way above its budget.
