A classic of comic insanity, At the Circus races, along at an hilarious, logic-defying pace, reaching literally the highest point in all of the Marx Brothers' films with a scene in which the zany trio - as well as Margaret Dumont and a gorilla on the loose - wind up swinging wildly from the trapeze. When a loan shark and two circus performers set out to steal Wilson's Wonder Circus from it's rightful owner, two circus attendants (Chico and Harpo) enlist the help of a lawyer.
