This was one of the films that Spencer Tracy really believed in and actively supported not because he starred in it, but because he was a great admirer of Thomas A. Edison. This was unusual as Tracy was known throughout most of his career to disparage his own gifts as well as the importance of motion pictures. Also, prior to this film Spencer Tracy had been a very active member of the "Academy of Motion Picture Arts and Sciences". He even hosted the awards show on at least one occasion. However when the nominations came out for the best films of 1940, Tracy was appalled that "Edison the Man" was so overlooked in the nominations. It was only nominated for best writing. Tracy swore he would never attend another academy award ceremony again. He never did. Not without irony is that although he was nominated another 6 times over the next 28 years, Tracy never won another Oscar after that after winning two in a row in the previous two years.

This movie was made only 9 years after the real Thomas A. Edison died.

In the film, Edison and his wife communicate with each other by tapping out Morse code. In the movie this is presented as a charming endearment, but in fact Thomas A. Edison was so deaf that the only way he and his wife could talk was by tapping Morse code on each other's hands.

The World Premiere for this film in Thomas A. Edison's hometown of West Orange, New Jersey, serves as the backdrop for the mystery novel "Dead at the Box Office" by John Dandola. The novel explains in great detail how M.G.M. went about planning and carrying out the festivities.

This film was first telecast in Cincinnati Sunday 10 February 1957 on WXIX (Channel 19) (Newport KY), followed by Seattle Monday 11 February 1957 on KING (Channel 5) and by Omaha Wednesday 13 February 1957 on WOW (Channel 6); in Hartford CT it first aired 2 March 1957 on WHCT (Channel 18), in Minneapolis 7 April 1957 on KMGM (Channel 9), in Chicago 29 June 1957 on WBBM (Channel 2), in Philadelphia 27 September 1957 on WFIL (Channel 6), in Altoona PA 25 October 1957 on WFBG (Channel 10), and in San Francisco 9 September 1958 on KGO (Channel 7); New York television viewers got their first look at it 11 February 1959 on WCBS (Channel 2), but in Los Angeles its premiere telecast did not take place until Sunday 9 October 1960 on KTTV (Channel 11).

The banquet used as a framing device was the opening and dedication of "The Edison Institute," now more popularly known as Greenfield Village and The Henry Ford Museum in Dearborn, Michigan, which took place on the 50th anniversary of the invention of the incandescent light bulb.
