Lady Be Good is an American musical film directed by Norman Z. McLeod and starring Eleanor Powell, Ann Sothern, Robert Young, Lionel Barrymore, and Red Skelton.

Since she and Young were known primarily as light comic stars, the studio brought in Powell for a supporting role, but gave her top billing to attract audiences.

This film's most notable sequence involves an epic tap dance routine by Powell, to the melody of Gershwin's "Fascinating Rhythm" (another song taken from the play).

The film won an Academy Award for Best Song for "The Last Time I Saw Paris," composed by Jerome Kern and Oscar Hammerstein II.

A few years later, now married and successful songwriters with a hit Broadway show behind them, Dixie realizes that Eddie is spending more time in rich New York society than composing.

The opening of Dixie's show is represented by the legendary “Fascinatin’ Rhythm” production number featuring Eleanor Powell.

The name Lady Be Good was bestowed on an American B-24D Liberator bomber, which flew for the United States Army Air Forces during World War II out of North Africa.
