This is the real Marx deal. After the weak and flimsy movie debut proper with "Cocoanuts" the second Marx's film sees them under better directorial control with better technical back-up and far more assured and confident performances.
One or two weak songs aside (thankfully we also have the classic "Captain Spaulding" ditty to make up for that dreadful love song) this is almost all undiluted Marx madness as the director Victor Herman wisely took a knife to the song and dance routines.
And what Marxian gems we have! Chico and Harpo are on top anarchic form with a big dash of surrealism (the boxing/wrestling match that pits Harpo against poor old Margaret Dumont is an un-PC joy for the eyes) and Groucho is at his verbal best as he quick fires some of the best Marx gags to perfection.
Top of the list has to be the wonderfully absurdist skit between Chico and Groucho when Chico puts forth his ideas to find out who stole the painting (the basic plot is a nonsensical mess but matters not) which goes from asking the people in the house who took the painting, to asking the people in the house next door who took the painting, to having to build a house next door to ask as there isn't one, to the layout of this fantasy house, to finally coming to the conclusion that in fact left-handed moths ate the picture...Absurd genius superbly delivered.
Other highlights (in what is easily a film at its strongest when being verbal) are Groucho's attempts to propose to two women at the same time.
Woman - "Why, that's bigamy"!
Groucho - "Yes, and it's big o' me too"
Groucho - "I'm sick of these conventional marriages. One woman and one man was good enough for your Grandmother, but who wants to marry your Grandmother? Nobody, not even your Grandfather".
The classic dictation of a letter sequence (the only time Zeppo is given anything to do)
Groucho - "Read that back to me".
Zeppo - "... care of Hungerdunger, Hungerdunger, Hungerdunger, and McCormick."
Groucho - "You've left out a Hungerdunger. You left out the main one, too!
And the scene where Groucho introduces himself to Chandler.
Groucho - "Well, art is art, isn't it?
Still, on the other hand, water is water.
And east is east and west is west, and if you take cranberries and stew them like applesauce, they taste much more like prunes than rhubarb does".
Not much Groucho/Dumont word play on show sadly but there is one gem;
Groucho - "You're the most beautiful woman I've ever seen, which doesn't say much for you".
All in all though this is pure Marx Brothers genius!
