According to the Variety review, M-G-M originally planned a picture that would encompass Edison's entire life, but when the studio found that it had too much material, it decided to divide the film into two parts. The second part, Edison the Man, starring Spencer Tracy, dealt with the adult Tom Edison and was also released in 1940. According to news items in Hollywood Reporter, technical advisor Lewis Miller was Edison's nephew. At the Port Huron, MI, premiere of the film, a wood-burning locomotive pulling a baggage car in which Edison worked as a boy was displayed outside the theater. In December 1940, Mickey Rooney starred in a Lux Radio Theatre version of this story. In 1963, M-G-M produced a television movie titled The Wizard of Menlo Park, which was also based on the life of Tom Edison.
