Mediocre Hitchcock overall with some exceptional sequences in the early going. When the locale switched to Cuba, though, it comes off as an extended episode of "Mission Impossible". Some severe editing was called for here. It's obvious this was a studio job for Hitch and not a picture he felt strongly about. Still the acting is good, there are many noteworthy shots and scenes. It just goes on too long and there is an uncharacteristically bad use of music in this film. It's quite jarring and distracting in several sequences. Disappointing.
