The last Marx Brothers Paramount feature before they got fired and moved to MGM. I vaguely remember the backstory being that this film bombed, thus why the boys were terminated. Why the hell it bombed, I have no idea--this may be their funniest Paramount. The story is simple enough; a fictional country ousts their leader in order to appoint Groucho as the head man in charge, leading to a war & the intro of Chico and Harpo; and I guess Zeppo was there, too.
Too many funny lines and scenes to cover--Be sure to wash your neck, peanuts, Harpo jumping into the lemonade, the running gag with the sidecar, and the war at the end, especially Harpo grabbing Margaret Dumont's ass. And, Harpo's brief encounter with Edgar Kennedy's wife.
The rest of the Marx Brothers career at MGM is debatable, but they got off to a great start with "A Night at the Opera" and "A Day at the Races."
