The Marx Bros. revert to the rousing physical comedy and staccato gag dialog of their earlier pictures in At the Circus.Story is slight but unimportant. Kenny Baker, owner of a circus, is harrassed by pursuing James Burke, who wants to foreclose the mortgage he holds on the outfit. When Baker’s bankroll is stolen, Chico and Harpo call in Groucho to straighten out the difficulties. Groucho winds up by selling the circus for one performance to Margaret Dumont, Baker’s rich aunt and Newport social leader. Chico does his pianolog in circus car, while Harpo’s turn for a harp solo is set up in the menagerie with a production and choral background. A colored kid band and adult chorus (from Hollywood company of Swing Mikado) are used here.
