- The role of Bunny Watson is based on the real librarian that built up the research library at CBS.
- The movie is adapted from the Broadway play, which opened in 1955 and held 296 performances.
- The machine in the movie is called "EMARAC", which stands for Electromagnetic Memory and Research Arithmetical Calculator. It is based on the actual first general purpose electronic computer, ENIAC, whose slogan was "Making machines do more, so that man can do less".
- The sound effects that were created specifically to depict the EMARAC were re-used in several future films, including Fantastic Voyage (1966).
