Movie Review: The Courier (2020). Amazon Prime.

Benedict Cumberbatch and Rachel Brosnahan star in a cold war spy thriller and docudrama about the Soviet spy Oleg Penkovsky, and the British businessman who was recruited to carry his secrets from Russia to MI6 and the CIA.  Cumberbatch plays the businessman courier, and Brosnahan plays the role of his wife. 

Taut, suspenseful and based on the real life story, with an excellent and believable performance by Cumberbatch.  Recommended.
