After resolving a test with a sequence of numbers, four mathematicians are challenged by a mysterious man called Fermat (Federico Luppi) to meet in an isolated place to resolve the greatest enigma ever. Each one receives a code name - Hilbert (Lluís Homar),Pascal (Santi Millán ),Galois (Alejo Sauras) and Oliva (Elena Ballesteros) - and heads to a barn in an island. Inside the barn, they find a comfortable room, and sooner their host arrives. They have dinner together and Fermat receives a phone call from the hospital where his daughter in interned in coma. He asks to leave the place for one hour; however, after his departure, the quartet finds that they are locked up in the room. They receive a phone call with a mathematical riddle, giving one minute to their reply; sooner they find that if they do not answer to the questions, the walls move and room shrinks pressed by four Poseidon hydraulic presses. While responding the questions, they try to find the motives why they have been gathered together to be killed.

"La Habitación de Fermat" is another variation of "Cube", with an intriguing premise and a disappointing resolution. The beginning is original, and the suspenseful story works very well until the moment that the identity and motives of the insane murdered are disclosed. Then the plot turns to ridiculous, too complicated for an issue between two men. Would be necessary such expensive and complicated scheme to eliminate a competitor? Further, the fate of Fermat and the policeman is silly and the black humor of the joke with the security belt does not work. My vote is six.

Title (Brazil): Not Available

When it comes to math, it might have been better to put Greeks in a room. But joking aside (and maybe also the fact that no Greek filmmaker came up with this idea, which could be seen as a shame),this is a really good and suspenseful movie. I won't say much about the movie and the story, because it unravels at its own pace and it's something the viewer should experience as such.

There have been quite a lot of thrillers that are coming from Spain and most of them are really good too. If you can watch them (either with subtitles if you don't know the language like or dubbed),you will get a really good and suspenseful experience out of them. While there are better movies than this one, this is still a very good movie

Neighter the story deepens as expected; thus the mysteries of the movie fails to raise tension, nor the narration presents a satisfying visual attraction. Good idea, sufficient prologue and unsatisfactory final.
