Fermat's Room (La Habitación de Fermat)

SAW for the mathematically minded, with less blood and more brains. Spanish film FERMAT’S ROOM brings together four mathematicians, locks them in a room and lets the walls crush them. The enigmatic Fermat invites four experts in their field to solve a puzzle. Asked to abandon their phones the trail leads to a remote warehouse. At which point it all seems like a bad joke. Until, that is, the first proper challenge arrives backed by some serious motivation – a shrinking space being compacted by hydraulic presses. Entering similar territory to CUBE the only way out of this deathtrap is for the foursome to solve the riddles. But the bigger question they must ponder is who would actually want to kill them? This engrossing debut by writer-directors Luis Piedrahita and Rodrigo Sopeña will keep you in its grip until the very end.
