Alfred Hitchcock directed this cold war thriller that stars John Forsythe as American agent Michael Nordstrom, who is sent to interview a high-ranking Russian official who has defected to the U.S. with some vital information: that a ring of French spies codenamed Topaz has been stealing and selling top secret NATO information to the Russians. Alarmed, Michael calls in his French friend and colleague to get to the bottom of this, and expose the spy ring, to minimize the National Security damage that has been done. Forgettable film has an unoriginal plot and uninspired direction by Sir Alfred. Not a bad film really, but entirely unmemorable.
