Cocoanuts was the first feature film starring the four Marx Brothers: Groucho, Chico, Harpo and Zeppo. It may also have the distinction of being the first true movie musical, that is, a movie where the musical numbers were meant to be part of the story telling process rather than a performance for audience within the movie. It wasn’t that the studio didn’t plan to have a band playing with the musical scenes. A “band” was hired for the first day of shooting. Apparently they were to follow the actors around ready to play whenever someone was tempted to burst into song, but the director soon realized there was no reason to have them around and that they would distract from the plot of the movie; something that the Marx Brothers were already managing to do pretty well on their own.
