The iconic Marx Brothers -- Groucho, Harpo, Chico and Zeppo -- head for the high seas in the outrageously funny Monkey Business. While hiding from the authorities on a luxury cruise ship, a quartet of stowaways inadvertently find themselves posing as bodyguards to rival gangsters. Complete lunacy ensues as the brothers get mixed up in a kidnapping and must save the day. Featuring some of the legendary comedy team's wackiest scenes ever, including all four brothers each trying to pass themselves off as real-life actor Maurice Chevalier, this unforgettable film earned a place on the AFI's 100 Years 100 Laughs list.
