The scene in Key Largo in which the alcoholic girlfriend (Claire Trevor) of the mobster (Edward G. Robinson) sings a number off key while intoxicated was inspired by Mayo Methot, Bogart’s third wife. During World War II, the Bogarts traveled Europe entertaining the troops. At one point in their travels during the war, the Bogarts met up with director John Huston in Italy. During a night of heavy drinking, Methot insisted that everyone listen to her perform a song. Though they told her no, she sang anyway. The performance won Trevor an Academy Award.
