"TCM Classic Films Collection: The Marx Brothers" contains four feature films: "A Day at the Races," "A Night in Casablanca," "Room Service," and "At the Circus."
In "A Day at the Races" (1937), Groucho is Dr. Hackenbush, the epitome of quackery whose special patient is Mrs. Emily Upjohn (Margaret Dumont). There was never a better comic foil than Ms. Dumont and she is in great form here, especially when she undergoes a medical examination that includes a shoeshine, manicure, and shave. Groucho and Chico engage in a seven-minute routine in which Chico, hawking "tutsi-fruitsi ice cream," sells Groucho a racing tip which requires a succession of books to decode.
"At the Circus" (1939) is memorable mostly for Groucho's rendition of "Lydia, the Tattooed Lady," which became one of his signature songs. Margaret Dumont is on hand again, this time as Mrs. Dukesbury to Groucho's J. Cheever Loophole, and Eve Arden contributes her comic talents as Peerless Pauline, a shady acrobat.
