The film, directed by first time Spanish director-duo Piedrahita and Sopeña, was showcased in the Discovery section at the Tribeca Film Festival 2008.
The walls are closing in-literally-on four brainiac mathematicians with shadowy pasts in this übertense debut… Each has been invited by the mysterious Fermat to a sort of salon for riddle freaks, where they will try to solve an assuredly grand enigma… Solve it in one minute or the walls, rigged with mega hydraulic presses will begin to press in. With their lives on the line, these four brains must solve their most profound equation yet: Why is someone trying to kill them?
This is an intense movie that never lets up on the pace, with mini-climaxes and revelations at every turn, that you almost come to expect after a while. At the post-movie interview, the directors (who also wrote the movie) revealed that the movie was their tribute to the mega-hits Lost and 24. The seed of the idea: let’s put 4 people in a room, and have them confront a life threatening situation. The filmmakers chose mathematicians, as they are “scientific poets”.
This approach reflects in the fact that form and structure are the elements that make the movie click, and not some underlying premise. The filmmakers did not really have anything to say, rather a strong desire to implement Hollywood clichés in a very witty and entertaining manner, something their favorite TV series have done so well: they are film “constructionists“. If they weren’t filmmakers, they would be designing roller coasters.
