Cold Hell (DIR. Stefan Ruzowitzky) Cold Hell is a dark and gritty crime thriller written by Martin Ambrosch and directed by Stefan Ruzowitzky.  The film has been deservedly compared to other serial-killer thrillers like David Fincher’s Se7en;  though it doesn’t revolutionize the genre, Cold Hell’s adrenaline-fuelled brutality prove that following the usual formula isn’t always a bad thing.
