After the film was released, the telephone was commonly called the "Ameche," a slang term referring to actor Don Ameche who played the telephone's inventor. This association is explained in the film Ball of Fire (1941), showing the term was still in use two years after the release of the original film.
This is the only film featuring all four of the Young sisters: Loretta Young, Sally Blane, Polly Ann Young and Georgiana Young.
Alexander Graham Bell's daughter, Mrs. Gilbert Grosvenor, had official script approval.
Bell's wife Mabel Gardiner Hubbard, despite going deaf at age 5, became an exceptional speaker and lip reader as a result of the efforts of her parents.
This film had its premiere at the 1939 World's Fair in New York.
