If the viewer can keep up with all the directions given in this nifty little spy vs. spy thriller, he is a better man than I Gunga Din. It's amazing that Richard Myles (Fred MacMurray) can remember all the details. The viewer may also be amazed that Fred MacMurray speaks such good German. MacMurray is one of those great Hollywood actors who never received his due, even though he almost matched the performances of Edward G. Robinson and Barbara Stanwyck in the film noir classic "Double Indemnity." He certainly keeps up with Joan Crawford in "Above Suspicion," although the two simply don't jell as a team. Barbara Stanwyck would have made a much better partner for MacMurray in this film.
All that aside, this is still a topnotch suspense movie from World War II. The flick is fast-paced and has worn well with the passage of time, since all the goings on are now just history to most viewers. Since director Richard Thorpe was an old hand at directing action pictures he lets the show get on the road and move along rapidly. He throws humor in from time to time to ease the tension the way Hitchcock would do in a more masterful way. Viewers used to seeing Basil Rathbone play Sherlock Holmes will enjoy seeing him play a dastardly Nazi stooge who receives his just desserts. In the opposite direction viewers may also enjoy seeing Conrad Veidt playing a good guy who assists the newlyweds Frances and Richard Myles (Joan Crawford and Fred MacMurray)in their dangerous mission inside Nazi Germany. Those who enjoy World War II espionage films, should find this one a winner.
