Owing something to cult scarer Cube, Fermat’s Room sets out its stall as an intellectual horror movie. Four mathematicians are invited to an isolated house by the mysterious Fermat.
There they’re required to solve a series of logical problems - and if they fail or delay, the walls of the room they’re trapped in start to close in around them.
This feature debut for co-directors Luis Piedrahita and Rodrigo Sopeña is never quite as clever as it thinks it is, and there are some sizeable holes in the plot.
Still, with its teasing sense of play, you won’t be crawling the walls.
