This film sports winning performances (Alice Faye is delightful and very accomplished as a light comic actress), plenty of well-played comedy and well-staged action, a fine Alfred Newman score. But what really impressed and intrigued me were some elaborately staged outdoor scenes which appeared to be at least partially shot on a real 18th century seaport, not just the back lot. Either Fox spent a whole lot of money constructing a very large and realistic looking seaport set, or some of this was shot on location at some historic recreation site, or the art director was a genius in making the back lot look a lot bigger than it was. Interesting to see what a muscular hunk Fred MacMurray was, very different than his image in later years.
