Although some purists hold out for
Duck Soup (1933), many
Marx Brothers fans consider A Night at the Opera the team's best film. Immediately after the credits roll, we are introduced to
Groucho Marx as penny-ante promoter Otis B. Driftwood. After a sumptuous dinner with a beautiful blonde at a fancy Milan restaurant, Driftwood tries to cadge another free meal from his wealthy patroness, Mrs. Claypool (
Margaret Dumont). The dignified dowager complains that Driftwood had promised to get her into high society, but has done nothing so far. Otis B. counters by introducing Mrs. C to pompous opera entrepreneur Gottleib (
Sig Rumann); all Mrs. Claypool has to do is invest several hundred thousand dollars in Gottleib's opera company, and her entree into society is in the bag. Contingent upon this plan is Driftwood's signing of Rodolfo Lassparri (
Walter Woolf King), a self-important tenor. Backstage at the opera, Driftwood meets Fiorello (
Chico Marx), who poses as a manager and offers to sell Driftwood the "world's greatest tenor"-not Lassparri, as Driftwood assumes, but Fiorello's pal Ricardo Baroni (
Allan Jones). Instantly the two sharpsters try to draw up a contract ("The party of the first part shall hereafter be known as the party of the first part..."), which they proceed to tear up piece by piece whenever coming across a clause that displeases them (Driftwood: "That's a sanity clause"; Fiorello: "You no foola me. There ain't no Sanity Claus"). Having lost Lassparri to Gottleib, Driftwood sails back to America with Mrs. Claypool and the opera company. Gottleib arranges for Driftwood to get the tiniest, least accessible stateroom on the ship. Unpacking his trunk, Driftwood discovers that he's got to share his postage-stamp quarters with Ricardo Baroni, who has stowed away because he's in love with the opera troupe's leading lady Rosa (
Kitty Carlisle). Also hiding out in Driftwood's trunk is Fiorello, who's come along because he's still Ricardo's manager, and the wacky Tomasso (
Harpo Marx), Lassparri's former dresser, who has come along for the hell of it. Anxious to arrange a tete-a-tete with Mrs. Claypool in his stateroom, Otis finds out that his unwelcome guests won't leave until they're fed ("Do you have any stewed prunes? Well, give them some black coffee, that'll sober 'em up"). After ordering a huge dinner, Otis and his new friends are crowded even farther by a steady stream of intruders, including an engineer and his assistant, a cleaning lady, a manicurist, a girl looking for her Aunt Minnie, and a dozen waiters. The celebrated "stateroom scene" comes to a rollicking conclusion when Mrs. Claypool has the misfortune of opening the door. On the last night of the voyage, Fiorello, Tomasso and Ricardo sneak out of their stateroom to enjoy an impromptu ethnic festival in steerage. Ricardo sings, Fiorello "shoots the keys" on the piano, and Tomasso plays the film's theme song Alone on the harp. The stowaways are caught and thrown in the brig, but with Driftwood's help they escape. To avoid recapture, the stowaways don heavy beards and pose as three famed Russian aviators. After making a shambles of a public reception, the three reprobates hide out in Driftwood's New York apartment, where everyone conspires to drive an investigating detectiv
