The good thing about this film is that the directors made it on a shoestring budget only having to do one set , yet the movie works on many levels but is constantly reconfigured . ¨Fermat's room¨ bears special resemblance to ¨The cube¨ (by Vicenzo Natali) , as there's also a dangerously premise about strangers closed attempting to find an exit and resolving enigmas and using their mathematical skills they press forward and backward through the walls to avoid get smashed because the room is reducing itself . Cast is frankly well giving fine performances , though little known with exception the veterans Federico Luppi (Cronos) who holds a strong Argetinean accent and Luis Homar (Backwoods , Los Borgia) .
