Maths problems mixed together with some Spanish sounds as interesting and exciting as sending a text to someone sitting in the same room as you. However, directors Luis Piedrahita and Rodrigo Sopeña manage the unthinkable and combine both to create a suspense filled ninety minutes.

Plot as always in a few words as possible - A group of individuals are invited to a house to tackle a great enigma. No Irishman, Englishman or Scotsman in site. Rather three mathematicians and an inventor are the characters of this teasing thriller. The plot still doesn't sound too inviting as of yet, but when the guests arrive they are treated to a lovely meal. Again nothing out of the ordinary, but as the night develops the puzzles begin to arrive. And arrive they do, hand in hand with danger. The group must solve puzzles given by the host, as the walls that surround them quite literally begin to close in.

Acting as an almost intelligent and gore free Saw-like experience Fermat's Room is a slow burner of a movie. The first chunk of the movie is dedicated to the group arriving at the riddle infested home, which is understandable. No major problem there, but it would have been nice to arrive at the destination slightly earlier in the films duration. The acting is more than acceptable, and the majority of films that star Federico Luppi are usually more than worth your time. Fermat's Room is no exception.

It isn't a masterpiece or flawless by any means; there are a few little kinks here and there that are ever so slightly bothersome. But for the most part Fermat's Room is an involving and engaging film. It is filled with a number of thought provoking puzzles, which you could if you wish attempt to solve alongside the characters in the film as you are watching. Or you could just sit back and let the characters sweat it out in the confined space, probably the easier and stress free option. For a little under a fiver, Fermat's Room comes as an easy recommendation. It may not pack a cinema shattering punch of profoundness, but it will have you brain working and your eyes glued to the screen for its duration.

And in the end if you don't like it there are always other options available to you. You could do the obvious and resell or re-gift to someone that has a tweed jacket in their wardrobe. Or if worst comes to worst you could use it as a ruler or a counter balance in measuring wheat. Whatever you choose to do with it, Fermat's Room is worth a buy...
