Although it suffers from staginess and musical comedy plotting but gives the zany threesome plenty of comic elaboration. Classic Marx film with many funny sequences, this is the most sustained bit of insanity, full of crazy gags, antics and amusement, being now deemed a satiric masterpiece ,and one of the biggest hits. Their actions include some on stage antics during the stage debut, as they arrange for the normal tenor to be absent so that the young lover named Ricardo can get his chance. Later on, Marx Brothers anarchize the opera, insulting and mocking the guests and players. Driftwood (Groucho Marx) and two (Chico Marx as Fiorello and Harpo Marx as Tomasso) wacky friends of two (Kitty Carlisle as Rosa and Allan Jones as Ricardo) opera singers help them achieve success while humiliating their stuffy and snobbish enemies. It deals with a sly business manager named Otis B.

Groucho's wisecracks and the incomparable Chico and Harpo carry the movie. Amusing and entertaining Marx picture, it has a lot of funny material and unfortunately intrusive songs.
