The Courier movie review: Benedict Cumberbatch's spy thriller compromises on the suspense, but scores on the humane front

Based on real events at the height of the Cold War between America and Russia (then known as the Soviet Union), The Courier narrates the incidents that led to simple British businessman Greville Wynne (Benedict Cumberbatch) being recruited by the MI6 and CIA, and how he, in cohorts with decorated Soviet Union colonel Oleg Penkovsky (Merab Ninidze), helped avert the infamous Cuban missile crisis and reduce tension between the two nuclear superpowers to some extent.
