Beneath all the one-liners and amusing gags, this classic comedy has an undertone of satire that is quite effective. Jack Benny plays his role with just the right amount of exaggeration for it to work perfectly, and he, Carole Lombard, and the rest of the cast help Ernst Lubitsch to tell a lively yet worthwhile tale. There are a few slow spots early in the movie, but after it hits its stride, everything fits together well.
Very few film-makers can make something like this succeed, because they take themselves too seriously. Lubitsch does not, and as a result this film provides a caricatured but relatively insightful portrayal of the Nazis, with a light-hearted yet appreciative look at those who opposed them in the occupied countries. The right kind of lighter touch can sometimes be more effective in commenting on important issues than the heavy, emotionally laden harangues that are all too common.
While providing good entertainment, this movie also brings out the Nazis' inherent insecurity, pettiness, and short-sightedness, while also demonstrating their growing capacity for destroying the innocent. For example, the wonderful character actor Sig Ruman is greatly entertaining as a Nazi bureaucrat, yet he also cleverly brings out the pathetic side of such persons.
Aside from a couple of good gags, it starts off just a little slowly. A lot of time is spent on Robert Stack's character, who is (through no fault of Stack's) not very interesting. Likewise, the subplot involving him and Lombard takes up a lot more time than it was worth. Other than that, though, it moves briskly, with many entertaining scenes while it develops the story. As the pace picks up, the members of Benny's acting troupe get some fine moments of their own, Benny himself has some fine scenes with several other characters, and everything builds up nicely towards a good finale.
