Plot

Four stowaways, Groucho, Harpo, Chico, and Zeppo, are discovered aboard a luxury liner bound for New York and are chased for the entire voyage by Captain Corcoran and his crew. During the chase, Harpo joins a Punch and Judy show, and Chico and Harpo impersonate the ship's barber.¹

The gangster plot begins when Groucho hides in a closet in the stateroom of the gangster Alky Briggs and, emerging, flirts with Briggs's wife Lucille. Briggs hires Groucho and Zeppo as his bodyguards, while Chico and Harpo wander into the stateroom of his rival, the gang leader Joe Helton, to play chess and become his bodyguards. Briggs announces his takeover of Helton's territory but is ordered out with the help of Chico and Harpo, and Groucho later hires himself out to Helton as well.¹

When the ship docks, the stowaways try to get ashore by impersonating the singer Maurice Chevalier, whose passport Zeppo has stolen; each brother attempts the disguise in turn, and when the ruse fails they hide in a fainting man's stretcher and are carried off the ship.¹ The Chevalier sequence is frequently singled out by critics as a comic highlight.⁴ In the finale, Mary Helton is kidnapped at her coming-out party by Briggs's men; because Briggs has told Groucho of the plan, the brothers warn Helton and go to the barn where she is held, and Zeppo rescues Mary and knocks Briggs out during the fight.¹

Production

Origin of the story. While the team was still working on Broadway, Groucho Marx read Dawn Ginsbergh's Revenge, a novel by the young writer S. J. Perelman, invited him backstage, and asked whether he would write for the Marxes. Perelman's first assignment, teaming with W. B. Johnstone, was a radio script, and during its story conference the writers offered their single idea, the Marxes as stowaways on a luxury liner. Groucho decided to make it their next film and took the writers to Paramount's New York office to sign contracts.²

The first draft fared badly. According to legend, Groucho's response was "It stinks"; the writer Ned Tennant, who contributed uncredited gags, recalled a different but equally dismissive remark, "I think we need a script." Over the following five months the writers incorporated suggestions from gag writers, the brothers themselves, Mankiewicz, and McLeod, and the script kept changing during filming as the brothers improvised. McLeod learned to let the cameras roll when they began ad-libbing, often judging the improvised material better than what had been scripted.² In a contemporary interview, McLeod said up to twelve writers worked on the film, and that Eddie Cantor contributed ideas when he visited the set.¹

Credits and trivia. Although copyright records credit the cartoonist J. Carver Pusey as a contributing writer, modern sources refute any contribution by him to the final film and instead credit Nat Perrin.¹ Samuel Marx, father of the four brothers, made his film debut at the age of 72 in this film, reportedly earning $12.50 a day for two days.¹ The film went under the working title Pineapples, and scenes shot for it were included in Paramount's 1931 twentieth-anniversary promotional film The House That Shadows Built.⁵^•¹

Setting and style

The film was the first of the Marx Brothers' features shot on Paramount's Hollywood sound stages, and its production design is prominent: the stowaways emerge from barrels of kippered herring below deck into what a UCLA Film & Television Archive program note calls an art deco wonderland, from the ship's barber shop and promenades to a central staircase.³ Because it was written for the screen rather than adapted from a stage hit, contemporary and later critics noted it is noticeably less stagy than the earlier films, keeping plot at a minimum and anarchy at a maximum while retaining more narrative cohesion than some of the team's other pictures.⁴^•⁶

The Perelman controversy

The film launched a long-running dispute over how much credit belonged to S. J. Perelman. Later writers went so far as to claim the entire Groucho persona had been modeled on Perelman; the film historian Frank Miller notes it was actually refined by Groucho with the help of the writer-director George S. Kaufman. Groucho complained that Perelman's writing was too literary, objecting to a reference to the operetta The Student Prince with the remark, "The trouble is that the barber in Peru won't get it," referring to Peru, Indiana. Although Arthur Sheekman received the screenplay credit, a good deal of Perelman's work remained, and in later years Groucho claimed that all but a few lines of Perelman's work survived in the two films Perelman wrote for the team, Monkey Business and Horse Feathers.²

The two remained friendly for decades, giving a joint interview in the 1960s with the critic Kenneth Tynan, and Groucho's resentment surfaced only in his final years. His last statement on the issue, in The Grouchophile, was that Perelman "is a great writer with a brilliant comic mind that didn't always mesh well with the lunacies of the Marx Brothers."²

Reception and legacy

The film was a substantial box-office success that established the Marx Brothers as major film stars and helped all of its writers find further work in Hollywood; Perelman soon returned to his own projects in New York.² A contemporary review in The New Yorker by John C. Mosher called it "the best this family has given us," noting the novelty of a good beating for the usually slighted Zeppo in the grand finale.⁷ On the aggregate site Rotten Tomatoes the film holds a 90% Tomatometer from 20 reviews.⁴

The film is the third of the five Paramount Marx Brothers features, between Animal Crackers (1930) and Horse Feathers (1932), and Thelma Todd also appeared in Horse Feathers the following year.¹^•⁸ Universal, which now holds the Paramount library, has issued the film on digital, Blu-ray, and DVD, both singly and in the Marx Brothers Silver Screen Collection, and new 35mm preservation negatives and DCPs of the five Paramount films have been created for theatrical exhibition.⁹^•⁸ A 16mm print is held in the Groucho Marx Collection at the Smithsonian's National Museum of American History.¹⁰

Reported running times differ among reference sources: the AFI Catalog lists 77 to 78 minutes,¹ Rotten Tomatoes and Universal list 1 hour 18 minutes,⁴^•⁹ TCM lists 1 hour 21 minutes,¹¹ and the BFI lists 68 minutes.¹²
