This is a brilliant movie.
First i wanna say that Kate Beckinsale is a great actress and she looks like Rhona Mitra in this film especially around the eyes.
The Director / Writer Karen Moncrieff did a fantastic job.
The movie-plot is extremely intense and the girl in prison was way over the top (the character that is) this is a tense flick with unexpected plot-twists.
A very interesting motion picture.
