"Lux Radio Theater" broadcast a 60 minute radio adaptation of the movie on
March 2, 1942 with George Brent and Mary Astor reprising their film roles.
Mary Astor mimed playing the piano in this film extremely convincingly, being an accomplished pianist in her own right. However, the actual piano playing on the soundtrack was dubbed by Max Rabinowitz. When close-up shots were required, Norma Drury Boleslavsky 's hands are those we see on the piano.
Bette Davis and 'Mary Astor (I)' thought the original script was not very good. They ended up doing massive rewrites on the script themselves.
George Brent was a licensed pilot and did his own landings in the movie.
One of Mary Astor 's lines is, "Who brought me to this dump?" Eight years later Bette Davis said "What a dump!", one of her best known quotes, in Beyond the Forest. Both original scripts were written by Lenore J. Coffee.
When Pete returns from seeing his lawyer, early in the film, he finds Sandra's agent in the living room listening to her latest recording. This is an excerpt from the first movement of the Piano Concerto No 4 in D minor by Anton Rubinstein, a great rarity and certainly not recorded by anyone else in 1941. It was possibly chosen by Max Steiner because it was no longer in copyright, but whatever the reason, it was a most unusual and sophisticated choice.
