In 1957, Paramount forgot to renew the soundtrack rights which reverted back to the authors of the play (the studio did renew the picture rights, though). As a result the film could not legally be seen in the USA until 1974, when Universal, which had since purchased Paramount's film library, was persuaded by fan requests to re-release it.

During a rehearsal a test was made for a color movie process called Multicolor (a predecessor of Cinecolor) and the result was the first known footage of the Marx Brothers in color! The clip is silent and lasts only 15 seconds. The Marx Brothers also appeared in color in the film The Story of Mankind (1957) in which they appeared separately.

The violin part of Harpo Marx's harp/violin duet was played by Mischa Mischakoff who was later concertmaster of the NBC Symphony under Arturo Toscanini.

In the opening scenes Hives turns to speak to Mrs. Rittenhouse after his opening song, and his waistcoat is different. It continues to swap from one style to another throughout the movie.

In the scene where Harpo replaces the handgun for a rifle after he shoots himself in the foot, Hives can be seen in the background walking behind the column, clearly waiting to enter later in the scene.

In the opening credits, the first name of Groucho's character, Captain Spaulding, is spelled "Jeffrey". Moments later in newspaper clip, his first name is spelled "Geoffrey."

Capt. Spaulding: You know, you two girls have everything. You're tall and short and slim and stout and blonde and brunette. And that's just the kind of a girl I crave.

Mrs. Rittenhouse: Captain, this leaves me speechless.

Capt. Spaulding: How much would you charge to run into an open manhole?
