Four mathematicians are imprisoned in a shrinking room; with the walls closing in, they must try anything to escape this fatal puzzle.
Fermat's Room is a clever, high-concept Spanish thriller that distinguishes itself through its tight puzzle-box premise — mathematicians trapped in a shrinking room forced to solve riddles against time. The concept is genuinely inventive and executed with real tension, earning high marks for novelty. The cinematography is competent and claustrophobic but not visually distinguished. The acting is solid but unremarkable across the ensemble. The plot mechanics are engaging in the moment but lean heavily on contrivance and the reveal of the mastermind's motive feels underdeveloped and somewhat anticlimactic, with the ending failing to fully satisfy the expectations built by the setup.
