D: Sam Wood. Groucho, Chico, Harpo Marx, Kitty Carlisle, Allan Jones, Walter Woolf King, Margaret Dumont, Sigfried Rumann. The Marx Brothers invade the world of opera with devastating results. Arguably their finest film (a close race with DUCK SOUP), with tuneful music and appealing romance neatly interwoven. One priceless comedy bit follows another: the stateroom scene, the Party of the First Part contract, etc. This is as good as it gets.

D: Sam Wood. Groucho, Harpo, Chico Marx, Allan Jones, Maureen O'Sullivan, Esther Muir, Margaret Dumont, Douglass Dumbrille, Sig Ruman, Dorothy Dandridge. The Marxes wreak havoc at a sanitorium, where wealthy hypochondriac Dumont is the leading patient; often uproarious comedy features some of the trio's funniest set pieces (Chico selling race tips, the seduction scene, etc.). A perfunctory storyline and unmemorable songs keep it from topping its immediate predecessor, A NIGHT AT THE OPERA... but the comedy content is sensational.
