The film moves along at a breakneck pace, which is to its advantage. Sometimes the intrigue is laid on too thick, but things usually straighten out.

Diplomatic Courier is skillfully made, rich in twists and turns, but totally lacking in significance. This little cinematic escapade never goes beyond what it literally portrays.

Odd mixture of semi-documentary and spy film, with good cast.

An exciting Cold War espionage thriller that's well-acted and tautly directly by Henry Hathaway.
