For Eleanor Powell's dance-version of the song "Lady, Be Good", MGM auditioned several dogs, but none of them was able to do the required tricks. Finally, Powell bought a dog off a propman and trained it herself for several weeks so that the dance could be done as she wanted.
Originally, any song that was used in a movie was eligible for the Best Song Academy Award. Jerome Kern was himself upset at his win for "The Last Time I Saw Paris". Afterwards, he got the Academy to change the rule so that only original songs composed specifically for the movie were eligible.
The song "The Last Time I Saw Paris" caused a lot of controversy when it won the Oscar for Best Song, because it was not written for this movie. After Tony Martin had a hit recording in 1940, MGM bought the rights to the song for use in this movie.
The title to this film was used for the ill-fated WWII Air Force B-24D bomber the "Lady Be Good", which disappeared over the Libyan desert on April 5, 1943 after overflying their air base in a sandstorm. The wreckage of the crash was found 15 years later in 1958 at which point it was discovered that the crew had parachuted out of the plane and had attempted to walk across the desert to safety. The remains of Lady Be Good's crew were found two years later in 1960.
A second camera filmed Eleanor Powell's epic piano dance to the tune of Gershwin's "Fascinating Rhythm". This behind-the-scenes footage, which showed the off-camera work needed for this routine to work, is included in the documentary That's Entertainment! III (1994).
This film's initial television broadcast in Los Angeles took place Thursday 19 December 1957 on KTTV (Channel 11), followed by Philadelphia 11 May 1958 on WFIL (Channel 6), by San Francisco 9 September 1959 on KGO (Channel 7), and, finally by New York City 1 November 1959 on WCBS (Channel 2).
