Hossein Amini's script (based on John le Carre's book) has enough layers of morality and Hellenic drama to keep Susanna White's journeyman directing afloat. Helping out is d.p. Anthony Dod Mantle who applies an acid-yellow palette and never wastes any opportunity for an interesting camera angle. Most interesting is Stellan Skarsgard as a beefy, long-haired Russian mafia defector. One of his very best performances.
