The film stars the three brothers: Groucho Marx, Chico Marx, and Harpo Marx, plus Raymond Burr, Eric Blore, and, of all people, Marilyn Monroe! It is directed by David Miller and written by Frank Tashlin and Mac Benoff.
Harpo is up to his usual antics when he steals a tin of sardines and accidentally bags the Romanoff diamonds.
The film has a musical score and lyrics by Ann Ronnell.
