The Courier faithfully recreates the struggles of British businessman-turned-Cold War informant Greville Wynne with a plot that builds suspense until its heartfelt and historically accurate ending. Starring Benedict Cumberbatch as the titular courier, the 2020 political thriller shifts between Britain and the Soviet Union to capture the turbulent atmosphere on both sides of the war. Like the best Cold War movies, The Courier relies more on realistic dialogue-driven drama than extravagant spy action clichés. The fact that the protagonist’s real-life inspiration was not a spy but rather an ordinary salesman makes the biographical narrative all the more intriguing.
