Oh Sailor Behave

is a 1930 American pre-Code musical comedy film produced and released by Warner Brothers, and based on the play See Naples and Die, written by Elmer Rice.

An American newspaper reporter named Charlie Carroll (Charles King) is sent to Venice to interview a Romanian general, who is played by Noah Beery.

Meanwhile, Nanette learns that her sister is being blackmailed by Prince Kasloff of Russia (Lowell Sherman), to whom she wrote some incriminating letters.

Charlie, thinking she has eloped, consoles himself with Kunegundi (Vivien Oakland) and almost marries her until he realizes the truth about Nanette and that she has been kidnapped by the Prince.

They play the part of two American sailors stationed in Naples who attempt to find a wooden-legged thief who has robbed the navy storehouse in Venice.
