The irrepressible comedians in this quintessential anarchic, satirical film simply but irreverently attack the pomposity of small-time governmental leaders (Firefly as President), the absurdity of government itself (the Cabinet meeting scene), governmental diplomacy (the Trentino-Firefly scenes), an arbitrary legal system (Chicolini's trial), and war fought over petty matters (the mobilization and war scenes). The non-stop, frenetic film is filled with a number of delightfully hilarious moments, gags, fast-moving acts, double entendres, comedy routines, puns, pure silliness, zany improvisations, quips and insult-spewed lines of dialogue - much of the comedy makes the obvious statement that war is indeed nonsensical and meaninglessly destructive, especially since the word 'upstart' was the insult word (Ambassador Trentino called Firefly an 'upstart') that led to war between the two countries. It also contains a few of their most famous sequences:

• the lemonade seller confrontation
• the mirror pantomime sequence

Unlike many of their other features, there are no romantic subplots (with Zeppo) and no musical interludes that stop the film's momentum - no harp solos for Harpo and no piano solos for Chico. There are, however, a couple of musical numbers that are perfectly integrated into the plot:

• When the Clock on the Wall Strikes Ten
• Groucho's song with the chorus - the Freedonia Hymn Just Wait 'Til I Get Through With It
• the staged production number, The Country's Goin' to War (it was the only musical number in any of their films to feature all four of the brothers together)
