Cold War spy Greville Wynne and his Russian source try to put an end to the Cuban Missile Crisis. Thriller THE COURIER has many of the elements of more realistic spy thrillers, but by far its greatest strength is its characters. At its core, it explores the relationship between Greville Wynne, Oleg Penkovsky and their families. The performances are uniformly excellent. For a film otherwise focused on its characters, the picture is never completely clear what Wynne's civilian job was. Anyone expecting a James Bond action film may be seriously disappointed with this real-life tale.
