Monkey Business is a 1931 American comedy film starring the Marx Brothers. The third film by the brothers, it featured Groucho, Chico, Harpo, and Zeppo in their usual buffoonery, albeit this time aboard a fancy ocean liner crossing the Atlantic. As the four stowaways attempt to hide on the ship, they get coerced into becoming bodyguards for two feuding gangsters. When they arrive in the United States, one of the gangsters holds the other gangster's daughter hostage. The brothers then decide to save the day and rescue the girl. When the film premiered, it was heavily censored in some countries, for fear of inciting misbehavior amongst youth. This was the first Marx brother's film not to be adapted from a Broadway show and was a fantastic success at the box office. Also starring Rockliffe Fellowes, Harry Woods, Thelma Todd, Ruth Hall, and Tom Kennedy, Monkey Business was directed by Norman Z. McLeod.
