Shmeckle’s review published on Letterboxd:
Compelling true story about a regular British businessman who's recruited to be a courier of intel from the Soviet Union to prevent nuclear war. Didn't know the story and was quite interested and Benedict Cumberbatch makes a shocking transformation.
Great performances, but the staid tone, very British, seems to hold it back from being truly great. Though, one moment is quite powerful and... almost emotional.
