Rodrigo Cortes, the Spanish filmmaker behind this diabolical, Hitchcock-influenced narrative stunt, makes merry mischief with camera angles and lighting; the viewer feels suffocated along with Reynolds...
Rodrigo Cortes keeps the action bound to the box, limiting his lighting to naturalistic approximations, so that much of Reynolds's performance consists of him grunting and heaving in the dark.
Although the entire movie takes place in the enclosed space, director Rodrigo Cortes and writer Chris Sparling are ingenious in creating more plausible action than you would expect possible.
As a cautionary tale about the perils of nation building, this is both creepy and provocative, but director Rodrigo Cortes blows it in the last few minutes with a rushed ending that feels like a cheat after all the escalating tension.
Nothing this underrated actor has done previously measures up to the emotional diversity, focus and self-control required of him in a one-man exercise in underground suspense that Alfred Hitchcock would envy.
If the aim is to be unpredictable and to revel in cynicism, you run the risk -- realized here -- that the movie becomes more an authorial statement of purpose than a story the audience can believe in.
