"Horse Feathers" is the shortest Marx Brothers film, and you can see why: with a super-thin "plot", and minimal time given to the supporting characters, the brothers have nearly the entire movie to themselves. Even the musical numbers, which usually slow down their movies, are integrated into the comedy here: Groucho's "I'm Against It" is probably the quintessential Marx song, and all four variations of the trademark "Everyone Says I Love You" have a comic flair to them. I agree with those who say that although Zeppo Marx might not have been as comically gifted as his brothers, he was a far more entertaining "straight man" than all the replacements they used in their later films. In my opinion, "Horse Feathers" is second only to "Duck Soup" for pure Marx madness with little outside interference. If you agree, tie on the bed, throw the rope out the window. *** out of 4.
